The Hospital Readmissions Reduction Program (HRRP) is one of the most consequential and most controversial quality-based payment programs in Medicare. Authorized at Section 1886(q) of the Social Security Act through Section 3025 of the Affordable Care Act of 2010 (Public Law 111-148) and effective fiscal year 2013, HRRP reduces Medicare payments to hospitals with higher-than-expected 30-day all-cause readmission rates for six condition-specific measures: acute myocardial infarction (AMI), heart failure (HF), pneumonia (PN), chronic obstructive pulmonary disease (COPD), elective total hip arthroplasty and total knee arthroplasty (THA/TKA), and coronary artery bypass graft (CABG) surgery. The maximum payment reduction is 3 percent of base operating Inpatient Prospective Payment System payments, applied annually based on three-year rolling measurement periods.
For Georgia, HRRP is enormous and consequential. Every major IPPS hospital in the state, including Grady Memorial Hospital, Emory University Hospital, Emory University Hospital Midtown, Northside, Piedmont Atlanta, Children's Healthcare of Atlanta, Memorial Health Savannah, AU Medical Center, Phoebe Putney Memorial Hospital, Atrium Health Floyd, Northeast Georgia Medical Center, Wellstar Kennestone, Wellstar Cobb, and dozens of others, participates in HRRP and faces annual readmission rate measurement, penalty determination, and payment adjustment. Critical Access Hospitals (rural Georgia CAHs with 25 or fewer beds) are excluded from HRRP, reflecting their cost-based reimbursement framework. Maryland hospitals are excluded due to Section 1814(b)(3) of the Social Security Act demonstration arrangements. Cancer hospitals and hospitals with insufficient case volume are also excluded.
The methodology is sophisticated and technical. Yale Center for Outcomes Research and Evaluation (Yale CORE) developed and maintains the HRRP measures using hierarchical logistic regression risk adjustment that accounts for patient age, gender, comorbidities, and clinical severity. The methodology produces a Risk-Standardized Readmission Rate (RSRR) and an Excess Readmission Ratio (ERR = Predicted / Expected) for each measure for each hospital. Hospitals with ERR above 1.0 may face penalty.
Section 15002 of the 21st Century Cures Act of 2016 (Public Law 114-255) fundamentally reformed HRRP by adding peer group stratification effective fiscal year 2019. Research and advocacy had demonstrated that safety-net hospitals (those serving high proportions of dual eligible Medicare-Medicaid beneficiaries) faced disproportionate penalty concentration because the original HRRP risk adjustment did not account for socioeconomic status. The peer group reform divided hospitals into five groups based on dual eligible patient proportion and compared each hospital's performance to median performance within its peer group rather than to national average. For Georgia hospitals serving high dual eligible proportions (Grady, Memorial Savannah, Phoebe Putney), the peer group reform was substantial and significantly reduced penalty exposure.
This guide is for Georgia hospital administrators, quality directors, care transitions teams, healthcare consultants, and Medicare beneficiaries. We explain the Section 1886(q) framework, the six condition-specific measures, the methodology, peer group stratification, exclusions, care transitions programs (Project RED, Project BOOST, Transitional Care Model, INTERACT, Care Transitions Intervention), Georgia Medical Care Foundation Quality Innovation Network support, MedPAC analyses, AHA litigation, and how Georgia hospitals approach HRRP compliance and improvement.
The statute: Section 1886(q) and Section 3025 ACA
The HRRP was created by Section 3025 of the Affordable Care Act of 2010, which added Section 1886(q) to the Social Security Act. The statute directs CMS to:
"... reduce the amount of payment ... to applicable hospitals with respect to applicable conditions that the Secretary determines have excess readmissions."
The original statute set:
- Effective date: FY 2013
- Maximum reduction: 1% (FY 2013), 2% (FY 2014), 3% (FY 2015 and subsequent)
- Initial measures: AMI, HF, PN
- Authority for additional measures over time
Section 15002 21st Century Cures Act
Section 15002 of the 21st Century Cures Act of 2016 (Public Law 114-255) reformed HRRP by adding peer group stratification. The change responded to substantial research and advocacy showing that safety-net hospitals faced disproportionate penalty concentration.
Section 15002 added Section 1886(q)(8) authorizing the peer group methodology. The reform was effective FY 2019.
Statutory rationale
Congress recognized that:
- Unplanned readmissions are often preventable
- Readmissions represent costs to Medicare and disruption for beneficiaries
- Hospitals have substantial influence over readmission risk through discharge planning, care coordination, and post-discharge follow-up
- Financial incentive could drive quality improvement
- Public reporting could create reputational incentive
Statutory limitations
Congress also recognized:
- Some readmissions are unavoidable
- Risk adjustment is essential
- Safety-net hospitals serve sicker patients with more social complexity
- Peer group comparison addresses safety-net hospital concerns
The six condition-specific measures
HRRP measures six conditions, each with separate measurement and penalty calculation:
Acute Myocardial Infarction (AMI)
- Patients admitted with primary diagnosis of AMI (heart attack)
- 30-day all-cause readmission rate
- Established since FY 2013
Heart Failure (HF)
- Patients admitted with primary diagnosis of heart failure
- Largest measure by patient volume
- Established since FY 2013
Pneumonia (PN)
- Patients admitted with pneumonia diagnosis
- Definition has been expanded over time (sepsis with secondary pneumonia, aspiration pneumonia)
- Established since FY 2013
Chronic Obstructive Pulmonary Disease (COPD)
- Patients admitted with COPD exacerbation
- Added in FY 2015
Total Hip and Total Knee Arthroplasty (THA/TKA)
- Elective primary THA/TKA admissions
- Added in FY 2015
- Different patient population (primarily elective surgical)
Coronary Artery Bypass Graft (CABG)
- CABG surgery admissions
- Added in FY 2017
- Cardiac surgery patients
Measure addition over time
CMS may add additional measures through rulemaking. New measures must be evidence-based and demonstrate substantial readmission burden.
The methodology
Yale CORE measure development
Yale Center for Outcomes Research and Evaluation developed the HRRP measures under CMS contract. The methodology is consistent across measures and has been refined over time.
30-day all-cause readmission definition
- 30 days following hospital discharge
- All-cause (not just same diagnosis)
- Excludes planned readmissions (specific list of planned procedures)
- Excludes same-day readmissions
- Excludes admissions to non-acute facilities
- Includes readmissions to any hospital (not just the index hospital)
Hierarchical logistic regression risk adjustment
For each measure, Yale CORE develops a risk adjustment model that accounts for:
- Patient age
- Patient gender
- Comorbidities (identified through ICD codes from current and prior admissions)
- Severity indicators
- Various clinical factors
The models are reviewed and updated periodically.
Important limitation: socioeconomic status
The risk adjustment models do not directly adjust for socioeconomic status (income, dual eligible status, race, ethnicity, education, etc.). This was a major concern that led to Section 15002 Cures Act peer group reform.
Risk-Standardized Readmission Rate (RSRR)
For each hospital and each measure:
- Predicted = number of readmissions predicted by model using hospital's patient mix
- Expected = number of readmissions expected at national average performance with same patient mix
- RSRR = (Predicted / Expected) × National Mean Rate
Excess Readmission Ratio (ERR)
- ERR = Predicted / Expected
- ERR > 1.0: hospital readmissions higher than expected for its patient mix
- ERR = 1.0: hospital performs as expected for its patient mix
- ERR < 1.0: hospital readmissions lower than expected for its patient mix
Three-year rolling measurement period
- Measures use three years of discharge data
- Each year, the oldest year drops off and the newest year is added
- More statistically stable than single-year data
- Reduces year-to-year noise
Statistical significance
Yale CORE methodology accounts for statistical uncertainty:
- Confidence intervals around ERR
- Hospitals where ERR is not statistically different from 1.0 may not face penalty
- Small-volume hospitals may have insufficient data
Payment reduction calculation
Aggregate Payments for Excess Readmissions
For each hospital with ERR > 1.0 on at least one measure, CMS calculates:
- Excess readmissions for each measure with ERR > 1.0
- Aggregate dollar value of excess readmissions
- Hospital's share of payment reduction
Maximum 3 percent reduction
- Effective FY 2015 and subsequent (FY 2013: 1%; FY 2014: 2%; FY 2015+: 3%)
- Cap on reduction applied to base operating IPPS payments
- A hospital with substantial excess readmissions on multiple measures hits the 3% cap
Application through claim payment and cost report
- Reduction applied at claim-level throughout the year
- Final settlement reflects HRRP reduction
- Worksheet E Part A of Medicare cost report applies HRRP reduction
Annual HRRP final rule
CMS publishes HRRP results annually:
- Hospital-specific ERR for each measure
- Penalty amount
- Effective dates (typically October 1 of each year)
Public availability
Hospital-specific HRRP performance is publicly available:
- Hospital Compare / Care Compare website
- CMS public datasets
- Various third-party analyses
Section 15002 Cures Act peer group stratification
Background of reform
By 2015-2016, substantial research from academic medical centers, MedPAC, AHA, AAMC, America's Essential Hospitals, and others had documented:
- Safety-net hospitals (high dual eligible proportion) had higher readmission rates
- HRRP risk adjustment did not account for socioeconomic status
- Penalty concentration at safety-net hospitals
- Equity concerns about HRRP impact on vulnerable populations
Section 15002 reform
Section 15002 of the 21st Century Cures Act of 2016 added peer group stratification to HRRP. Key features:
Five peer groups
Hospitals are divided into five peer groups based on proportion of dual eligible patients:
- Group 1: Lowest dual eligible proportion (typically <8%)
- Group 2: Lower-middle (typically 8-15%)
- Group 3: Middle (typically 15-22%)
- Group 4: Upper-middle (typically 22-30%)
- Group 5: Highest dual eligible proportion (typically >30%)
(Specific thresholds vary year-to-year and by methodology.)
Comparison within peer groups
Each hospital's ERR is compared to median ERR within its peer group:
- Hospitals above peer group median: potential penalty
- Hospitals at or below peer group median: no penalty
- Quintile distribution affects penalty calculation
Effect on safety-net hospitals
- Reduced penalty concentration at safety-net hospitals
- More equitable framework
- Did not eliminate penalties entirely (high-performing safety-net hospitals still receive no penalty; low-performing ones still face penalty within their peer group)
Effective FY 2019
The peer group methodology became effective FY 2019. Earlier years used the original methodology.
Continuing refinement
CMS has continued refining peer group methodology through annual IPPS rulemaking.
Hospitals excluded from HRRP
Critical Access Hospitals
Section 1820 of SSA. CAHs are reimbursed on cost basis under 42 CFR 413, not IPPS. Not subject to HRRP. Numerous rural Georgia hospitals are designated CAHs and excluded.
Maryland hospitals
Section 1814(b)(3) demonstration. Maryland operates a different hospital payment system through CMMI demonstration. Maryland hospitals are not subject to standard HRRP.
Cancer hospitals
Designated PPS-exempt cancer hospitals (e.g., MD Anderson, Memorial Sloan Kettering, City of Hope). Excluded from HRRP.
Hospitals with insufficient cases
Hospitals with too few cases for any given measure to produce statistically reliable measurement are excluded for that measure. Small-volume hospitals.
Religious nonmedical health care institutions
Excluded due to nature of care.
Children's Healthcare of Atlanta
Children's hospitals (CHOA, Egleston, Scottish Rite) have separate considerations. Not all HRRP measures apply because of pediatric population.
Care transitions programs
The most direct response to HRRP has been hospital implementation of care transitions programs. Multiple evidence-based models have been developed.
Project RED (Re-Engineered Discharge)
Developed by Boston University Medical Center. Eleven-step protocol focused on:
- Patient education during admission
- Medication reconciliation
- Follow-up appointment scheduling before discharge
- After-Hospital Care Plan (a personalized written document)
- Telephone follow-up after discharge
Research shows Project RED reduces readmissions in implementation studies.
Project BOOST (Better Outcomes for Older adults through Safe Transitions)
Society of Hospital Medicine program. Focuses on:
- Risk assessment using the 8P risk scale (Problem medications, Psychological problems, Principal diagnosis, Polypharmacy, Poor health literacy, Patient support, Prior hospitalization, Palliative care needs)
- Tailored interventions
- Hospital-to-home transitions
- Patient and family engagement
BOOST has been implemented at hundreds of hospitals.
Transitional Care Model (TCM)
Developed by Mary Naylor (University of Pennsylvania). Advanced practice nurse-led intervention:
- Hospital visit during admission
- Home visit within 24-48 hours of discharge
- Subsequent home visits as needed
- Phone contact between visits
- Extended follow-up (1-3 months)
TCM has substantial evidence base. Effective for chronic conditions.
INTERACT (Interventions to Reduce Acute Care Transfers)
Florida Atlantic University program. Skilled nursing facility-focused:
- Early identification of acute changes in resident condition
- Care pathways for common conditions
- Communication tools (SBAR)
- Reduces SNF-to-hospital transfers
Important for hospitals discharging to SNFs.
Coleman Care Transitions Intervention (CTI)
Developed by Eric Coleman (University of Colorado). Coaching-based:
- Coach visit during hospitalization
- Home visit within 1-2 days of discharge
- Phone contact follow-up
- Four pillars: medication self-management, dynamic patient-centered record, primary care follow-up, knowledge of red flags
Evidence-based. Particularly effective for older adults.
Hospital-developed programs
Many hospitals combine elements of various models or develop hospital-specific approaches. Common elements:
- Care coordinator (nurse, social worker)
- Medication reconciliation by pharmacist
- Follow-up appointment scheduling
- Discharge phone calls
- Coordination with primary care and skilled nursing
Implementation challenges
- Workforce requirements (nurses, social workers, pharmacists)
- Information technology integration
- Coordination across settings
- Sustaining program over time
- Quality measurement

GMCF is part of national network of QIN-QIOs serving different states. Network sharing of best practices and resources.
Hospital Compare and public reporting
Care Compare website
CMS's Care Compare website (formerly Hospital Compare) provides public access to hospital quality data including:
- HRRP performance by condition
- HVBP performance
- HACRP performance
- Patient experience scores
- Many other quality metrics
Public reporting transparency
Consumers, payers, and others can see hospital-specific data. This creates reputational incentive beyond financial penalty.
Effect on hospital reputation
- Hospital marketing and patient choice
- Insurer network decisions
- Employer health plan considerations
- Local press coverage
Hospital data analytics
Most hospitals invest substantially in:
- Internal HRRP performance dashboards
- Real-time readmission tracking
- Predictive analytics for high-risk patients
- Care management workflows triggered by risk scores
Combined effects with other quality programs
A hospital's quality-based payment can be reduced through three programs simultaneously.
Hospital Value-Based Purchasing (HVBP)
Section 1886(o) of SSA. Section 3001 of ACA 2010. Different program with up to 2% withhold redistributed based on quality performance. Measures include:
- Clinical care
- Patient experience (HCAHPS)
- Safety
- Efficiency (MSPB)
A hospital can lose up to 2% (and gain depending on performance).
Hospital-Acquired Condition Reduction Program (HACRP)
Section 1886(p) of SSA. Section 3008 of ACA 2010. Different program with 1% payment reduction for bottom quartile hospitals on HAC measures. Measures include:
- CDC NHSN healthcare-associated infections (CLABSI, CAUTI, SSI, MRSA, C. diff)
- PSI 90 patient safety composite
Combined effect
A hospital with poor performance across all three programs:
- HRRP up to 3%
- HVBP up to 2% withhold
- HACRP 1%
- Combined potential: 6%+ payment reduction
For a hospital with $100 million base IPPS, this could be $6+ million annual revenue impact.
Strategic implications
Hospital quality programs must address all three simultaneously. Investments in care transitions (HRRP), patient safety (HVBP, HACRP), patient experience (HVBP), and efficiency (HVBP MSPB) are interconnected.
MedPAC analyses of HRRP
Effectiveness research
MedPAC has analyzed HRRP effectiveness over the years. Findings include:
- Readmission rates have decreased nationally since HRRP implementation
- Decrease may reflect both real care improvement and shifts in admission patterns
- Mixed evidence on whether the decrease has translated to improved patient outcomes
Unintended consequences
MedPAC and other researchers have identified concerns:
Observation status increases
Hospitals may admit some borderline cases as observation status rather than inpatient to avoid future readmission counting. Observation status:
- Outpatient (Part B)
- Different patient experience
- Different financial implications for beneficiaries
- HRRP measures inpatient discharges, so observation does not trigger readmission risk
ED returns without admission
Hospitals may discharge from ED without admission when previously they might have admitted. Patient receives ED care but no admission counted.
Post-acute care substitution
Hospitals may discharge to home health, SNF, or other post-acute settings rather than discharge to home, hoping to avoid readmission.
Mortality concerns
Some research suggests possible mortality increases in heart failure patients. Research is contested. Hypothesis: hospitals may delay or avoid admissions to improve readmission metrics, with adverse mortality consequences.
Equity concerns
- Safety-net hospital concentration of penalties (largely addressed by Cures peer groups)
- Continued socioeconomic concerns
- Racial and ethnic disparities
Reform recommendations
MedPAC has recommended various HRRP modifications. Most have not been fully implemented. Section 15002 Cures Act peer groups represent the major reform.
AHA litigation and advocacy
AHA position
AHA has historically:
- Supported the principle of quality improvement
- Opposed specific HRRP elements deemed unfair to certain hospital types
- Advocated for socioeconomic adjustment (achieved through Cures peer groups)
- Participated in litigation on specific methodology issues
Litigation history
Various AHA and individual hospital lawsuits have addressed:
- Risk adjustment methodology
- Measure specifications
- Penalty calculation methodology
- Procedural issues
Most major HRRP statutory provisions have been upheld. CMS implementing rules have been adjusted through litigation in some cases.

- Various peer groups depending on facility
- Wellstar system-wide quality programs
Piedmont facilities
- Multiple Atlanta-metro and Georgia hospitals
- Various peer groups
- Piedmont system-wide programs
Northside Hospital
- Atlanta-metro
- Various locations
- HRRP-subject
Children's Healthcare of Atlanta (CHOA)
- Children's hospital
- Pediatric population
- HRRP measures focused on adult conditions; CHOA application limited
Worked example 1: Grady Memorial Hospital HRRP
Grady's profile suggests:
- Dual eligible proportion >30% (Group 5 peer group)
- High readmission rates absolute
- Risk-adjusted comparison to peer group median (other high-dual-eligible safety-net hospitals)
- Penalty likely modest given peer group framework
- Pre-Cures Act peer groups: substantial penalty risk
- Post-Cures Act: penalty risk substantially reduced
Numerical illustration
- Grady base IPPS: ~$150M annually
- Hypothetical HRRP penalty: 0.5% to 1.5% of base IPPS (varies year)
- Penalty: $750K to $2.25M annually
- Significant but manageable
Care transitions investment
- Multi-disciplinary care transitions team
- Coordination with Grady-affiliated primary care
- Coordination with community resources
- Pharmacist medication reconciliation
- Social work support
Worked example 2: Peer group analysis under Cures
Hypothetical Hospital A (dual eligible 35%, Group 5):
- ERR for HF: 1.06
- Group 5 median ERR for HF: 1.03
- Hospital A's relative performance: 0.03 above median (penalty)
Hypothetical Hospital B (dual eligible 12%, Group 2):
- ERR for HF: 1.06
- Group 2 median ERR for HF: 1.00
- Hospital B's relative performance: 0.06 above median (larger penalty)
Both hospitals have same absolute ERR (1.06), but the peer group methodology gives Hospital A relatively lower penalty because the peer group it competes against also has high absolute ERR.
Pre-Cures methodology would have compared both hospitals to national average:
- Both 1.06 vs national average ~1.0
- Identical large penalty for both
- Hospital A (safety-net) faced disproportionate penalty
Worked example 3: Phoebe Putney rural HRRP
- Rural southwest Georgia
- High dual eligible proportion (Group 4-5)
- Substantial Medicaid and uninsured share
- Local primary care availability variable
- Rural skilled nursing facility coordination challenging

Penalty profile
- Group 4-5 peer group comparison
- Penalty risk moderate
- Investments to maintain peer group ranking
Worked example 4: AU Medical Center academic HRRP
- Academic medical center
- Complex case mix (higher acuity)
- Moderate dual eligible proportion
- Likely Group 3 peer group
- Risk adjustment methodology relevant
- Care transitions program
Six condition-specific performance

- Coordination with Savannah-area SNFs and home health
- Coastal Georgia geography (drive time considerations)
Worked example 6: Care transitions program
Imagine a comprehensive care transitions program at a Georgia hospital:
Multi-disciplinary team
- Care coordinator nurse (RN, often BSN)
- Pharmacist medication reconciliation specialist
- Social worker (community resources, social determinants)
- Patient education specialist
- Discharge planning nurse
Workflow
Admission: identify high-risk patients (using validated risk score like LACE+, HOSPITAL, or 8P) During admission: education on diagnosis and self-management Pre-discharge: medication reconciliation, follow-up appointment scheduled, after-hospital care plan Discharge: care plan handoff to patient, family, primary care Post-discharge day 1-3: phone call from care coordinator Post-discharge day 7-14: follow-up appointment with primary care or specialist Post-discharge day 30: program completion or extension
Investment
- Team of 5-10 FTEs for medium-sized hospital
- Annual cost: $500K-1.5M
- Expected return: reduced readmissions, reduced HRRP penalty, improved patient outcomes
Evidence base
- Strong evidence for care transitions effectiveness
- ROI calculation: penalty savings vs program cost
- Patient outcomes beyond financial: improved health, satisfaction
Common HRRP compliance and quality improvement issues
Error 1: Risk adjustment not adequate for socioeconomic status Pre-Cures Act, this was the major concern. Section 15002 Cures Act peer groups largely addressed.
Error 2: ICD coding affecting comorbidity capture Risk adjustment depends on ICD coding. Incomplete coding can lead to insufficient risk adjustment.
Error 3: Observation status workarounds Some hospitals shift to observation status to avoid future readmission counting. Inappropriate observation use is itself problematic.
Error 4: ED return without admission Patient may return to ED multiple times without admission. Does not count for HRRP but represents quality and patient experience concern.
Error 5: Care transitions program inconsistency Programs may not be applied to all eligible patients. Inconsistent implementation reduces effectiveness.
Error 6: Medication reconciliation errors Medication reconciliation at admission and discharge is critical. Errors are common cause of readmissions.
Error 7: Follow-up appointment access If primary care or specialty appointment is not available within 7-14 days, follow-up planning fails.
Error 8: Social determinants of health Patients with food insecurity, housing instability, transportation barriers, or other social factors have higher readmission risk. Programs must address these.
Error 9: Health literacy Patient education must match patient health literacy. Verbal teach-back is essential.
Error 10: Skilled nursing facility coordination Discharge to SNF requires coordination. Errors in handoff cause SNF-to-hospital transfers.
Error 11: Home health agency coordination Discharge to home health requires coordination with the HHA.
Error 12: Multiple chronic condition complexity Patients with multiple chronic conditions need integrated care planning.
Error 13: Mental health and substance use Mental health and substance use comorbidities are major readmission risk factors. Often inadequately addressed.
Error 14: Combined HRRP/HVBP/HACRP integration Hospitals must address multiple quality programs in integrated way. Silos reduce effectiveness.

HRRP, beneficiary access, and care quality
The HRRP creates financial incentive for hospitals to improve care transitions, discharge planning, and post-discharge follow-up. The ultimate goal is improved beneficiary outcomes through reduced unplanned readmissions.
Beneficiary perspective
For Medicare beneficiaries, HRRP creates pressure that should result in:
- Better discharge planning
- Better medication reconciliation
- Earlier follow-up appointments
- Phone calls after discharge
- Coordination with primary care
- Coordination with skilled nursing and home health
Beneficiary advocacy
Beneficiary advocacy organizations participate in HRRP debate from access and quality perspective:
- Center for Medicare Advocacy
- Medicare Rights Center
- National Council on Aging
- AARP
Implications for vulnerable beneficiaries
Section 15002 Cures Act peer groups responded to concerns that vulnerable beneficiaries at safety-net hospitals were harmed by HRRP through reduced hospital resources and potential adverse practices. The reform was substantial improvement but continuing attention to safety-net hospital quality and resources remains important.
Beneficiary education
Care Compare website helps beneficiaries make informed hospital choice decisions. Hospital readmission rates publicly available.

SNF coordination
Skilled nursing facilities are major receivers of hospital discharges. SNF-to-hospital readmissions are substantial component of HRRP. Coordination strategies:
- Standardized handoff communication
- INTERACT-style early identification at SNF
- Pre-discharge SNF acceptance verification
- Post-discharge follow-up with SNF
Home Health Agency coordination
Home health agencies often receive hospital discharges. HHA-to-hospital readmissions occur. Coordination strategies:
- Start of care visit within 24-48 hours of discharge
- Medication reconciliation
- Education and assessment
- Communication with primary care
Hospice transition
For appropriate end-of-life patients, transition to hospice can prevent unnecessary readmissions. Hospice election by Medicare beneficiary requires:
- Terminal illness diagnosis with prognosis ≤6 months
- Voluntary election of hospice benefit
- Section 1812 and Section 1813 of SSA
Long-term care transitions
For patients requiring long-term care, transition planning to nursing facility or other long-term care setting is essential.

HRRP measure technical specifications
The Yale CORE measure specifications are extraordinarily detailed and run to hundreds of pages per measure. The technical complexity is one reason HRRP penalty calculation is opaque to many stakeholders, including hospital clinical staff who may not understand precisely how their patient population produces a specific ERR.
Index admission definition
Each measure begins by defining the population of index admissions. The general framework:
- Medicare fee-for-service beneficiaries (Part A enrollment)
- Age 65 or older for most measures
- Discharged alive from an acute care hospital subject to IPPS
- Specific principal diagnosis (e.g., AMI ICD-10 codes for AMI measure)
- Not transferred to another acute care hospital
- Not enrolled in hospice during admission
- Not against medical advice (AMA) discharge
Index admission exclusions
Specific exclusions per measure further narrow the population:
- Hospital discharges within 30 days before index admission (to avoid double-counting)
- Specific clinical exclusions (e.g., for AMI: same-day transfers, certain comorbidities)
- Hospital-acquired conditions that complicate measurement
- Patients without continuous Medicare Part A enrollment in baseline period
- Patients with key data missing from claims
Outcome definition
The 30-day all-cause readmission outcome is:
- Any unplanned readmission to any acute care hospital
- Within 30 days of discharge from index admission
- For any cause (all-cause)
- Excluding planned readmissions per CMS planned readmission algorithm
Planned readmission algorithm
CMS developed and maintains an algorithm identifying readmissions that are planned and therefore excluded from HRRP measurement. Planned readmissions include:
- Scheduled procedures (e.g., elective hip replacement)
- Chemotherapy for cancer
- Transplantation
- Maintenance procedures (e.g., dialysis access)
- Rehabilitation
- Specific diagnosis groups identified as typically planned
The algorithm produces conservative identification of planned readmissions to avoid inappropriately excluding readmissions that should count.
Risk factor selection
Risk factors included in the hierarchical logistic regression models were selected based on:
- Clinical relevance to the outcome
- Statistical association with readmission
- Reliability of measurement in administrative claims
- Avoiding gaming or perverse incentives
Specific risk factors vary by measure but typically include age, sex, comorbid conditions captured in 12-month look-back claims, and severity indicators. The Yale CORE measure specifications document exactly which factors enter each measure's risk-adjustment model.
Hierarchical model details
The hierarchical logistic regression model has two levels:
- Patient level: individual patient characteristics predict probability of readmission
- Hospital level: hospital-specific random effect captures unexplained variation across hospitals
The hospital random effect represents what the model attributes to the hospital after accounting for patient mix. This is the basis for the RSRR calculation. Hospitals with random effects significantly above zero are penalized; hospitals with random effects significantly below zero are recognized as performing better than expected.
Bayesian shrinkage
The hierarchical model produces shrinkage that pulls small hospital estimates toward the national average. This addresses statistical concern that small hospitals would otherwise have extreme estimates based on few cases. Shrinkage:
- Reduces variability for low-volume hospitals
- Increases precision of estimates
- Reduces extreme values
- Effectively provides "borrow strength" across hospitals
The result is that very small hospitals are unlikely to be assessed as either far above or far below average, even if their unadjusted rates would suggest extreme performance.
Public reporting timelines
The HRRP timeline involves:
- Measurement period: three years
- Data collection: claims submitted and processed through Medicare
- Measure calculation: typically 9-12 months after end of measurement period
- Public reporting on Care Compare: shortly before fiscal year of penalty application
- Penalty application: October 1 fiscal year start
The lag between care delivery and penalty application is approximately 1.5-2 years. This means quality improvements implemented today will not affect penalties for two to three years.
Hospital-Specific Report
CMS produces a Hospital-Specific Report (HSR) for each hospital subject to HRRP. The HSR includes:
- Hospital-specific results for each measure
- Index admission counts
- Readmission counts
- Calculated rates and ERRs
- Peer group assignment
- Penalty calculation
- Comparison to peer group
The HSR is provided to hospitals during a preview period before public reporting. Hospitals can review for technical errors during the preview period.
Preview period and corrections
The preview period is approximately 30 days. During the preview period, hospitals can:
- Review HSR for data accuracy
- Identify claim coding errors
- Verify index admission and readmission counts
- Submit corrections through specified processes
- Submit appeals on limited grounds
Most preview period corrections involve clear coding errors or claim processing issues. Substantive disagreement with methodology or risk adjustment cannot be resolved through preview period correction.
Worked example 7: Wellstar Kennestone HRRP scenario
Wellstar Kennestone Hospital in Marietta is a major Wellstar Health System hospital with significant Medicare volume. Hypothetical illustration:
- Index admissions across six measures: approximately 5,000 over three-year period
- Distribution: HF ~30%, PN ~25%, AMI ~15%, COPD ~15%, THA/TKA ~10%, CABG ~5%
- Observed readmission rates within typical range for community teaching hospitals
- ERR calculation by measure shows three measures with ERR slightly above 1.0
- Aggregate Payments for Excess Readmissions calculation
- Payment Adjustment Factor of 0.4 percent
- Annual reduction approximately $1.2 million on $300 million Medicare IPPS base
Wellstar Kennestone's response includes:
- System-wide care transitions program
- Discharge planning standardization
- Medication reconciliation protocols
- Post-discharge phone calls within 72 hours
- Coordination with Wellstar primary care offices
- Coordination with skilled nursing facilities
- Home health agency partnerships
The Wellstar system approach leverages integrated delivery system advantages, including shared electronic health record across hospitals, primary care, urgent care, and ambulatory specialty, supporting continuity that reduces readmissions.
Worked example 8: Northeast Georgia Medical Center HRRP scenario
Northeast Georgia Medical Center (NGMC) in Gainesville is the major hospital for northeast Georgia, serving a regional population including parts of the southern Appalachian region. Hypothetical illustration:
- Index admissions: approximately 4,200 over three-year period
- HF measure represents largest share given chronic disease burden in service area
- Patient population includes substantial rural and lower-income beneficiaries
- ERR for HF and PN slightly above 1.0
- Peer group assignment in middle dual eligible band
- Payment Adjustment Factor of 0.5 percent
- Annual reduction approximately $850,000 on $170 million Medicare IPPS base
NGMC response includes:
- Regional care coordination program
- Telemedicine for post-discharge follow-up given large service area
- Partnership with regional primary care
- Coordination with regional skilled nursing facilities
- Patient education materials in multiple languages reflecting community demographics
- Community health worker integration
The NGMC case illustrates how regional and rural community hospitals approach HRRP differently than urban academic centers, with particular attention to geographic distance to follow-up care and community resources.
Worked example 9: rural Georgia critical access hospital HRRP exclusion
Several rural Georgia hospitals are designated Critical Access Hospitals and therefore excluded from HRRP. Examples include various small rural hospitals across south and middle Georgia. CAH exclusion means:
- No HRRP measure calculation
- No HRRP penalty
- Continued cost-based reimbursement at 101 percent reasonable cost
- No quality-based payment adjustment under HRRP
CAH status provides protection from HRRP penalties but does not exclude rural hospitals from quality improvement attention. CAHs participate voluntarily in quality measurement, including Hospital Compare reporting, even without HRRP financial consequence. CAHs work with GMCF QIN-QIO on quality improvement and care transitions. The Medicare Beneficiary Quality Improvement Project (MBQIP) is a specific CAH quality improvement program.
For rural Georgia communities, CAH exclusion preserves hospital viability while continuing to support quality improvement through technical assistance rather than financial penalty.
Worked example 10: Piedmont Healthcare system-level HRRP coordination
Piedmont Healthcare operates multiple hospitals across Georgia, including Piedmont Atlanta, Piedmont Henry, Piedmont Newnan, Piedmont Fayette, Piedmont Mountainside, Piedmont Athens Regional, Piedmont Macon, Piedmont Columbus Midtown, Piedmont Columbus Northside, and Piedmont Cartersville. Each hospital is subject to HRRP individually.
System-level approach includes:
- Centralized quality improvement infrastructure
- Standardized care transitions program across hospitals
- Shared electronic health record (Piedmont uses Epic) supporting continuity
- Coordinated discharge planning standards
- System-wide medication reconciliation protocols
- Coordinated post-discharge follow-up
- Coordinated primary care follow-up
- Coordination with Piedmont Clinic for ambulatory follow-up
- Coordinated relationships with skilled nursing facilities and home health agencies
Each Piedmont hospital reports HRRP results individually, but system-level coordination supports quality improvement across the system. The Piedmont approach illustrates how multi-hospital integrated systems leverage scale and integration to address HRRP while maintaining hospital-specific accountability.
Hospital quality improvement infrastructure
Effective HRRP response requires substantial quality improvement infrastructure within the hospital.
Quality and patient safety department
Most hospitals subject to HRRP maintain dedicated quality and patient safety department with:
- Chief Quality Officer or equivalent senior leader
- Quality improvement specialists
- Patient safety officers
- Data analysts
- Clinical informaticists
The department coordinates HRRP response across clinical and operational departments.
Care management and discharge planning
Care management is the operational front line for readmission reduction. Hospital care management includes:
- Case managers (RN typically)
- Social workers
- Discharge planning specialists
- Transition coaches in some programs
- Pharmacy support
Case managers assess readmission risk, coordinate discharge planning, facilitate post-discharge service arrangements, and communicate with patients and families.
Physician leadership
Physician leadership engagement is essential for clinical practice change that reduces readmissions. Physician leaders include:
- Hospitalist medical directors
- Service line medical directors (e.g., cardiology for HF, pulmonology for COPD)
- Chief Medical Officer
- Department chairs
Physician engagement drives clinical pathway development, attending physician practice patterns, and physician-to-physician handoff with primary care and post-acute providers.
Information technology infrastructure
HRRP response requires substantial information technology including:
- Electronic health record with discharge planning workflows
- Risk stratification tools (e.g., LACE score)
- Medication reconciliation tools
- Patient education modules
- Patient portal for post-discharge engagement
- Population health management platform
- Real-time alerts for readmissions
- Data analytics for HRRP performance
Many hospitals use commercial readmission prediction tools (e.g., Epic readmission risk score, Cerner readmission risk model, or third-party predictive analytics) integrated with EHR.
Data analytics
HRRP performance analysis requires data analytics capabilities:
- Hospital-level HRRP performance trending
- Service line analysis
- Patient cohort analysis
- Care transition effectiveness analysis
- Predictive modeling
- Comparative benchmarking
- Root cause analysis of readmissions
Hospitals invest in business intelligence and data analytics teams to support quality improvement decision-making.
Community partnerships
Effective readmission reduction extends beyond hospital walls. Community partnerships include:
- Primary care provider relationships
- Skilled nursing facility partnerships
- Home health agency partnerships
- Community paramedicine programs
- Community health worker programs
- Community-based organization partnerships
- Faith-based and community organization engagement
- Transportation partnerships
The most effective readmission reduction programs view the hospital as one component of a community health system rather than the sole locus of care.
Social determinants of health and HRRP
The relationship between social determinants of health (SDOH) and readmission rates is well-documented in the research literature. Beneficiaries with adverse social determinants experience higher readmission risk regardless of clinical quality of hospital care.
Documented SDOH effects on readmissions
Research identifies SDOH factors associated with higher readmission risk including:
- Low income
- Low educational attainment
- Limited English proficiency
- Housing instability and homelessness
- Food insecurity
- Transportation barriers
- Social isolation
- Limited health literacy
- Mental health and substance use disorders
These factors persist after discharge and affect ability to obtain follow-up care, medications, food, and stable housing essential for recovery.
Hospital SDOH screening
Many Georgia hospitals now conduct routine SDOH screening including:
- Food security questions
- Housing stability questions
- Transportation access questions
- Financial strain questions
- Social support questions
- Mental health and substance use screening
SDOH screening identifies patients with high-risk profiles requiring enhanced discharge planning and community-based support.
Hospital SDOH interventions
Hospital interventions addressing SDOH may include:
- Discharge medication delivery to home
- Transportation arrangement for follow-up appointments
- Connection to food assistance programs (SNAP, Meals on Wheels, food banks)
- Housing instability case management
- Behavioral health connection
- Social work involvement
- Community health worker engagement
These interventions are not directly captured in HRRP measurement but indirectly support readmission reduction.
CMS attention to SDOH
CMS has increasingly recognized SDOH in quality measurement:
- Section 15002 Cures Act peer groups indirectly capture SDOH through dual eligible proportion
- CMS Health Equity Index in HVBP incorporates dual eligible patient performance
- Future HRRP may include direct SDOH adjustment
- CMS Office of Minority Health publishes equity-focused analyses
The trajectory is toward more explicit SDOH consideration in quality programs, though direct SDOH risk adjustment in HRRP has not been implemented.
HRRP in the context of broader healthcare reform
HRRP is one component of the broader healthcare reform under the ACA and subsequent legislation. Related programs include:
Hospital Value-Based Purchasing (HVBP) within ACA reform
Section 1886(o) authorizes HVBP, which adjusts IPPS payments based on:
- Clinical care domain
- Person and Community Engagement domain (formerly Patient Experience)
- Safety domain
- Efficiency and Cost Reduction domain
- Health Equity Adjustment (added 2024)
HVBP redistributes 2 percent of IPPS payments from below-average performers to above-average performers, with net effect dependent on performance score relative to peers.
Hospital-Acquired Condition Reduction Program (HACRP) within ACA reform
Section 1886(p) authorizes HACRP, which reduces IPPS payments by 1 percent for hospitals in the worst-performing quartile on hospital-acquired conditions including:
- Healthcare-associated infections (CAUTI, CLABSI, SSI, MRSA, C. diff)
- PSI-90 patient safety indicators
Medicare Promoting Interoperability Program
Section 1886(n) authorizes Promoting Interoperability (formerly Meaningful Use), which adjusts IPPS payments based on EHR meaningful use.
Medicare Spending Per Beneficiary
A measure within HVBP, MSPB compares hospital-attributed Medicare spending per beneficiary to national average, creating incentive for efficient care delivery.
Accountable Care Organizations
Section 3022 of ACA established Medicare Shared Savings Program ACOs, which create population-level accountability for cost and quality. Georgia ACOs include various physician groups and integrated systems.
Bundled Payment Programs
Bundled Payments for Care Improvement (BPCI) and BPCI Advanced create episode-level payment for various procedures and conditions. These programs share readmission reduction objective with HRRP.
Patient-Driven Payment Model
PDPM for SNF and PDGM for home health adjust post-acute payment, indirectly affecting post-acute partner incentives for hospital coordination.
The combined effect of these reform programs is to shift hospital payment from pure volume-based fee-for-service toward value-based payment integrating quality, cost, and outcomes.
HRRP enforcement and dispute resolution
While HRRP penalties are largely formulaic based on measure calculations, certain dispute and review mechanisms exist.
Preview period review
As described above, hospitals review HSR during preview period and identify technical errors.
Limited reconsideration
CMS allows reconsideration on limited grounds, primarily:
- Clear data errors
- Calculation errors
- Eligibility issues (e.g., hospital status as CAH or excluded)
- Specific methodology application errors
No substantive appeal of methodology
Hospitals cannot appeal the underlying measure methodology, risk-adjustment models, or peer group methodology through individual review. These are matters of CMS rulemaking subject to notice-and-comment rulemaking and potential judicial review of rulemaking.
Judicial review of rulemaking
HRRP rules and methodology can be challenged through judicial review of final rulemaking. AHA, AAMC, and individual hospital systems have participated in various litigation challenges to specific HRRP methodology decisions over the years.
Provider Reimbursement Review Board
The PRRB has limited HRRP jurisdiction. Most HRRP disputes do not proceed through PRRB but rather through the limited reconsideration process and through judicial review of rulemaking.
Hospital strategic considerations
Hospital leadership considers HRRP in broader strategic context.
Quality reputation
Beyond direct financial penalty, HRRP performance affects:
- Care Compare public reporting
- Hospital reputation
- Patient choice
- Referral patterns
- Physician recruitment
- Payor contracting
- Bond ratings
- Community standing
For Georgia hospitals competing in major metropolitan markets like Atlanta, quality reputation is a significant strategic consideration.
Investment in care transitions
Investment in care transitions programs has demonstrated return on investment for many hospitals through reduced HRRP penalties and improved performance on related quality programs. ROI analysis typically considers:
- HRRP penalty reduction
- HVBP performance improvement
- HACRP performance
- Direct cost of preventable readmissions
- Indirect quality reputation benefits
- Community health benefit
Risk-bearing arrangements
Hospitals in risk-bearing arrangements (ACOs, capitation, bundled payments, Medicare Advantage at-risk contracts) have additional financial incentive for readmission reduction beyond HRRP. Hospital strategy increasingly integrates HRRP response with broader value-based payment strategy.
Workforce considerations
Effective care transitions programs require workforce including case managers, social workers, transition coaches, and care navigators. Workforce investment is necessary for sustained HRRP performance improvement.
Technology investment
Hospital technology investment for HRRP includes EHR enhancements, predictive analytics, patient engagement platforms, and care coordination technology. These investments often serve multiple purposes beyond HRRP.
Research evidence on HRRP effectiveness
The research literature on HRRP effectiveness is extensive and continues to evolve. Key findings:
Readmission rates have declined
Multiple analyses show that 30-day readmission rates for the targeted HRRP conditions declined substantially since HRRP took effect. Whether this decline is attributable to HRRP versus broader quality improvement trends, ICD coding practice changes, or observation status substitution remains debated.
Spillover effects
Research finds spillover effects on non-HRRP conditions, suggesting hospitals improved overall discharge practices rather than only targeting measured conditions. Spillover effects support the view that HRRP produced genuine quality improvement.
Mortality concerns
Some studies raised concern about possible increase in 30-day mortality following discharge for HF patients in the post-HRRP era. The interpretation is contested. Some researchers argue HRRP created incentive against admission of high-risk patients or for earlier discharge that contributed to mortality. Other researchers find no causal relationship and attribute observed mortality patterns to changes in patient population or coding.
Observation status increases
Hospital observation stay use increased substantially in the HRRP era. Observation stays are not counted as admissions for HRRP measurement, creating potential incentive for observation status that may not always serve patient interests, particularly given Medicare beneficiary cost-sharing implications.
Equity concerns in the research literature
Safety-net hospitals experienced disproportionate HRRP penalties before Section 15002 Cures Act peer group reform. Post-reform analyses suggest peer group methodology substantially reduced equity concerns but did not eliminate them.
Continuing research
MedPAC, CMS, academic researchers, and policy organizations continue to research HRRP effects. The Yale CORE methodology continues to evolve, and CMS continues to refine the program through annual rulemaking.
International comparison
The United States is not alone in implementing readmission-based hospital payment programs. Various OECD countries have implemented similar programs:
- England: NHS readmission penalties
- Germany: readmission tracking in DRG system
- Various jurisdictions in Canada and Australia
International comparison provides limited but useful perspective on HRRP design and effects.
HRRP and the future of value-based hospital payment
HRRP has been one of the most consequential and most studied of CMS value-based payment programs. The combined experience of HRRP, HVBP, HACRP, and other programs informs ongoing CMS strategy for value-based payment. The future direction likely includes:
- Continued refinement of measure methodology
- Greater attention to social determinants of health
- Greater attention to health equity
- Potential consolidation of multiple programs
- Integration with broader value-based payment
For Georgia hospitals, the trajectory means continued financial and operational attention to HRRP and related quality programs is essential to long-term financial health under Medicare.
