Georgia Medicaid Third-Party Liability (2026): Subrogation, Ahlborn, Liens

Third-party liability (TPL) is the federal Medicaid rule that requires private insurance, workers' compensation, auto insurance, and other liable parties to pay for medical care first, with Georgia Medicaid serving as the payer of last resort. The federal framework sits in the Social Security Act provisions on assignment of rights and state recovery from liable third parties; Georgia's operational lien process sits in the Official Code of Georgia. This guide walks through the federal framework, the Ahlborn and Wos Supreme Court limits on recovery, Georgia's lien process, coordination with workers' comp and auto insurance, and how to protect Medicaid eligibility after a settlement.

The federal third-party liability framework for Georgia Medicaid

Federal Medicaid law treats TPL as a fundamental program integrity rule. State Medicaid plans must take reasonable measures to identify legally liable third parties, seek reimbursement from them, require their insurers to accept the state's assignment of payment rights, require providers to bill third parties first, and make eligibility determinations without regard to potential third-party recovery. As a condition of Medicaid eligibility, beneficiaries assign their rights to medical-support payments to the state and agree to cooperate in pursuing third parties. The federal anti-lien statute generally prohibits Medicaid liens on a beneficiary's property before death, with a narrow exception for third-party recoveries for medical expenses, which is the exception the Supreme Court analyzed in Ahlborn.

The Ahlborn and Wos decisions limit recovery to the medical portion

Two Supreme Court decisions shape every state's TPL practice:

• Arkansas Department of Health and Human Services v. Ahlborn: the federal Medicaid anti-lien statute prohibits states from imposing a lien on the non-medical portion of a Medicaid beneficiary's tort settlement. State recovery is limited to the medical-care portion, even when the beneficiary received less than the full value of their medical bills.
• Wos v. E.M.A.: states cannot enforce statutory caps that presume a fixed percentage of any settlement is for medical expenses when the actual medical portion is less than that presumption.

The practical result: a Medicaid lien is limited to the medical-expense portion of a settlement, calculated proportionally.

Federal legislative history: BBA 2018 expansion was repealed

Congress briefly enacted a provision allowing states to recover from the entirety of a tort settlement, not just the medical portion, which would have effectively overridden Ahlborn and Wos. That expansion was repeatedly delayed and was ultimately repealed in subsequent appropriations legislation before it took effect. The Ahlborn and Wos framework remains the operative law in 2026; readers and counsel should confirm the current federal landscape with current CMS Coordination of Benefits and Third-Party Liability guidance.

Calculating the Ahlborn lien cap

The Ahlborn lien cap is calculated as:

Medicaid Lien Cap = Medical Expenses Paid by Medicaid x (Settlement Amount / Total Damages)

This requires either a court determination of total damages or a negotiated agreement between the beneficiary and the state Medicaid agency on the total-damages figure.

Worked example:

• Medicaid paid medical expenses of approximately eighty thousand dollars
• The beneficiary's total damages (medical plus lost wages plus future medical plus pain and suffering plus loss of consortium) approximate three hundred twenty thousand dollars
• The beneficiary settles for half of total damages, often due to liability limits or shared fault
• The maximum Medicaid lien is the medical expenses multiplied by the settlement-to-damages ratio (here, half)

Experienced personal injury attorneys further negotiate reductions for attorney fees and costs incurred to make the recovery under the federal common fund doctrine and state-specific negotiation practice.

Georgia's statutory framework for Medicaid third-party liability

The Department of Community Health's automatic subrogation and lien

Georgia's primary TPL statute is O.C.G.A. Section 49-4-149, which establishes the Georgia Department of Community Health (DCH) automatic subrogation and lien rights. The statute provides that DCH is automatically subrogated to the rights of any Medicaid recipient against a third party for medical care expenses paid by Medicaid; that DCH may file a lien upon any settlement, judgment, or award; that the lien attaches to the cause of action and to any settlement, judgment, or award; that notice of lien is filed with the clerk of the superior court of the county where the action is pending; and that failure to notify DCH can result in personal liability of the attorney and beneficiary for the lien amount plus interest and attorney's fees. Counsel should pull the current statutory text before filing.

The DCH Casualty Recovery Unit

The DCH Third-Party Liability and Casualty Recovery Unit is the operational arm that investigates and recovers from tort cases, auto accidents, workers' compensation claims, and other third-party liability situations. The unit sits within DCH's Office of Inspector General.

CMO subrogation in Georgia Medicaid third-party liability cases

Most Georgia Medicaid beneficiaries are enrolled in a Care Management Organization (CMO) under Georgia Families managed care. Each CMO has its own internal subrogation process for member injuries, coordinated with DCH.

When a CMO member is injured and the CMO has paid for the medical care, the CMO holds the operational lien, but DCH retains oversight and the federal Medicaid TPL framework still applies. Personal injury attorneys must coordinate with both the CMO and DCH.

Workers' compensation coordination

Georgia workers' compensation insurance has its own subrogation rights for medical expenses paid for work-related injuries, administered by the Georgia State Board of Workers' Compensation.

For a Medicaid beneficiary who is injured at work:

1. Workers' compensation is primary. The employer's workers' comp insurance pays for the medical care.
2. Medicaid is secondary. If workers' comp is delayed in acceptance or denies coverage, Medicaid may pay initially but is reimbursed once workers' comp is confirmed.
3. Third-party action. If the work injury was caused by a third party (defective product, negligent driver in a work-related auto accident), the injured worker may have a tort claim. Both workers' comp and Medicaid have subrogation rights against the third-party recovery.

The interaction can be complex; experienced workers' compensation attorneys typically negotiate both liens.

Auto insurance coordination for Georgia Medicaid third-party liability

Georgia is an at-fault state with mandatory liability insurance. Required minimum coverage and the underlying statutes are administered by the Georgia Office of Commissioner of Insurance and Safety Fire (OCI); pull the OCI minimum-coverage page for current dollar minimums before relying on a specific number.

Georgia repealed mandatory Personal Injury Protection (PIP) decades ago; PIP is no longer required, though Medical Payments coverage (Med Pay) is commonly purchased. Uninsured and Underinsured Motorist (UM/UIM) coverage is offered and commonly purchased; UM/UIM is treated as third-party recovery for Medicaid purposes under the Ahlborn framework.

For a Medicaid beneficiary injured in a motor vehicle accident:

1. Med Pay (if purchased) pays for medical first.
2. At-fault driver's liability insurance is primary for damages (medical plus lost wages plus pain and suffering) up to policy limits.
3. UM/UIM applies if the at-fault driver is uninsured or underinsured.
4. Medicaid pays for medical expenses while litigation is pending and recovers from the eventual settlement, judgment, or insurance proceeds. The lien is filed with the clerk of the superior court in the county where the cause of action is pending.

DCH typically files its lien within thirty to sixty days of injury notification. The beneficiary's attorney must address the lien before disbursing settlement proceeds.

Private health insurance coordination

If a Medicaid beneficiary has private health insurance (employer-sponsored, COBRA, ACA marketplace, TRICARE), Medicaid is secondary. The flow:

1. Provider bills the primary insurer first.
2. Primary insurer pays per its policy.
3. Provider bills Medicaid for the remainder, up to the Medicaid fee schedule under the federal lesser-of rule.
4. Medicaid pays only the lesser of the Medicaid fee schedule amount or the unpaid balance.
5. The beneficiary is generally not liable for any balance (Qualified Medicare Beneficiary balance-billing protections apply for dual eligibles).

Beneficiaries must disclose all health insurance at Medicaid enrollment and at each annual renewal. Failure to disclose can result in:

• Incorrect Medicaid payments that must be recovered
• Provider clawback for paying secondary when primary should have been billed
• In serious cases, fraud allegations under Title XIX

Notification requirements: what beneficiaries and attorneys must do

Under the Georgia TPL statute, beneficiaries and their attorneys must:

1. Notify DCH of any potential third-party liability situation (motor vehicle accident, slip-and-fall, medical malpractice, products liability, dog bite, premises liability).
2. Provide DCH with sufficient information about the cause of action (parties, date, nature, attorney representation).
3. Obtain DCH's release before disbursing settlement proceeds.
4. Cooperate with DCH in investigating the third party.

Practical timeline: notify DCH within thirty days of retaining counsel or filing a claim. The DCH Casualty Recovery Unit at 1-404-657-5468 will respond with the amount of Medicaid expenses paid and instructions for further coordination.

Consequences of failure to notify

Failure to notify DCH can result in personal liability of the attorney and beneficiary for the lien amount, plus interest at the statutory rate, plus attorney's fees in any enforcement action. This is the single largest avoidable mistake in Medicaid TPL practice. Attorneys who fail to address the DCH lien can face professional discipline and personal liability.

How to protect Medicaid eligibility after a settlement

A lump-sum personal injury or workers' comp settlement can exceed the Medicaid asset limit (for example, the longstanding two-thousand-dollar limit for Aged, Blind, and Disabled eligibility; the current Medicare Savings Program resource limit set each year by CMS under the federal Low-Income Subsidy alignment) and terminate Medicaid coverage. Pull current Georgia limits from DCH and current MSP resource limits from the Medicare Savings Programs page before relying on a specific dollar figure. Options to preserve eligibility:

Special Needs Trust (SNT)

Under the federal Special Needs Trust authorities described in SSA POMS SI 01120.203, settlement proceeds may be placed in a Special Needs Trust without counting as a Medicaid asset:

• First-party (self-settled) SNT: established for the beneficiary's own benefit, funded with the beneficiary's own funds (including settlement proceeds), with a Medicaid payback provision at death of the beneficiary up to amounts paid by Medicaid.
• Pooled SNT: managed by a nonprofit with individual sub-accounts for multiple beneficiaries; funds available for supplemental needs while preserving eligibility, with a similar payback provision.

SNTs are complex legal instruments. Consult an experienced elder law attorney before creating one; the State Bar of Georgia Lawyer Referral Service can help with referrals.

Structured settlement

A structured settlement converts lump-sum proceeds into a stream of periodic payments. The annuity itself is generally not counted as an asset, but the periodic payments are counted as income each month they are received. For Modified Adjusted Gross Income (MAGI) populations, this may or may not exceed income thresholds; for ABD populations, periodic payments above the income standard can terminate eligibility.

Spend-down on allowable expenses

Beneficiaries may spend down lump-sum proceeds on allowable expenses without violating the transfer rules:

• Home modifications for medical needs (ramps, grab bars, widened doorways)
• Medical equipment not covered by Medicaid
• Prepaid funeral expenses (irrevocable; verify the current Georgia funeral-trust cap with counsel)
• Vehicle purchase (one vehicle is exempt)
• Home improvements on primary residence

Burial fund or burial trust

A small burial fund is exempt from Medicaid assets, and a burial trust under Georgia law can hold larger amounts irrevocably for funeral expenses. Confirm the current dollar exemption and trust limits with counsel before structuring.

Worked examples of Georgia Medicaid third-party liability

Motor vehicle accident with policy-limits settlement: Sarah (34), Atlanta

Sarah's vehicle is T-boned by a drunk driver in March. She is Lifeflighted to a Level I trauma center with multiple fractures and internal injuries. Medicaid pays a substantial six-figure sum for the hospital and follow-up care. Sarah hires a personal injury attorney in April who notifies DCH of the cause of action. The drunk driver's auto insurance pays policy limits; Sarah's UM/UIM pays its policy limits. Total settlement is below total damages once lost wages, future medical, and pain and suffering are added. DCH's Ahlborn-capped lien is the medical expenses multiplied by the settlement-to-damages ratio. Sarah's attorney negotiates a further reduction for fees and costs, leaving a final DCH lien below the proportional cap.

Workers' compensation injury with third-party action: Robert (47), Augusta

Robert is injured when scaffolding collapses on a construction site. Medicaid initially pays for emergency care before workers' compensation accepts the claim and reimburses Medicaid; workers' comp then pays ongoing medical. Robert pursues a third-party action against the scaffolding manufacturer (defective product). The workers' comp insurer asserts subrogation under the Georgia workers' comp lien statute against Robert's third-party settlement; Robert's attorney negotiates that lien separately. DCH has no further claim beyond the amount already reimbursed by workers' comp.

Medical malpractice in a nursing facility: Eleanor (78), Macon

Eleanor falls in her nursing facility due to documented staffing deficiency. The injuries include a hip fracture, surgical complications, and post-surgical sepsis. Medicaid LTC pays for the nursing facility stay throughout, and Medicaid acute care pays for the hospital surgery and complications. Eleanor's daughter (as guardian) sues the nursing facility for negligence. The settlement allocates substantial portions to pain and suffering and punitive damages. DCH's lien is for the acute-care amount; the attorney negotiates an Ahlborn reduction for fees. The remaining estate proceeds pass through probate.

Hit-and-run with UM recovery: Marcus (29), Atlanta

Marcus is injured by a hit-and-run driver who is never identified. Medicaid pays for the emergency care. Marcus has UM coverage and recovers under his policy through his attorney. DCH files its lien against the UM proceeds; UM is treated as third-party recovery under the Ahlborn framework. The lien is calculated proportional to total damages and reduced for attorney fees and costs.

Premises liability slip-and-fall: Patricia (62), Decatur

Patricia slips on a wet floor at a supermarket and sustains an ankle fracture requiring ORIF surgery. Medicaid pays the medical bills. Patricia sues the supermarket for negligent maintenance and settles. DCH files its lien timely. The attorney negotiates an Ahlborn reduction citing fees and costs. Patricia then works with an elder law attorney to structure the proceeds (a combination of home improvements, an irrevocable burial trust, and a Special Needs Trust) to preserve ABD eligibility.

Undisclosed third-party health insurance: David (44), Atlanta

David has Medicaid and his wife has employer-sponsored insurance covering David as a dependent. David did not disclose the other insurance at Medicaid enrollment. David receives a course of medical services, and Medicaid pays the providers. DCH's Third-Party Liability and Casualty Recovery Unit later identifies the commercial coverage via a federal Medicaid data match. DCH bills the commercial insurer, which pays at its rate; Medicaid is reimbursed. David is notified to update his coverage information at DFCS. No fraud allegation follows because the non-disclosure was negligent rather than intentional; future renewals must accurately report all coverage.

Fifteen common mistakes in Georgia Medicaid third-party liability cases

1. Failing to notify DCH of a third-party action. Failure to notify can result in personal liability of the attorney and beneficiary for the lien amount plus interest and attorney's fees.
2. Assuming Medicaid liens can be ignored. DCH liens automatically attach to the cause of action and survive settlement; they must be addressed before disbursement.
3. Not knowing the Ahlborn and Wos framework. Many beneficiaries and even some attorneys assume Medicaid can claim the entire medical-bill portion. Recovery is actually limited to the medical-expense portion proportional to total damages.
4. Confusing third-party liability with estate recovery. TPL operates during the beneficiary's lifetime against third-party tortfeasors; estate recovery is the post-death program. They are separate.
5. Not disclosing other health insurance at Medicaid enrollment. Medicaid is the payer of last resort; failure to disclose other coverage creates incorrect-payment exposure and potential fraud allegations.
6. Failing to use a proper damages analysis for Ahlborn negotiation. Apportionment requires a credible breakdown: medical, lost wages, pain and suffering, future medical, loss of consortium, and other elements.
7. Settling without obtaining a DCH lien release. Settlement proceeds cannot be safely disbursed without DCH's written release.
8. Not coordinating workers' comp with Medicaid. Workers' comp is primary for work-related injuries; failure to bill workers' comp first while Medicaid pays creates clawback exposure.
9. Believing PIP coverage is mandatory in Georgia. PIP was repealed decades ago. Med Pay is optional; UM/UIM is offered and commonly purchased.
10. Not knowing CMO subrogation differs from DCH TPL. CMOs have their own subrogation operations; attorneys must coordinate with both the CMO and DCH.
11. Failing to negotiate the lien reduction for attorney fees. Ahlborn allows for reduction proportional to attorney fees and costs incurred to make the recovery; the federal common fund doctrine supports such reductions.
12. Not creating a Special Needs Trust to preserve Medicaid eligibility. Lump-sum settlements over the Medicaid asset limit terminate eligibility unless placed in an SNT or otherwise sheltered.
13. Confusing private insurer subrogation with Medicaid TPL. Private health insurers have ERISA-based subrogation rights that operate differently and may not be reduced under the Ahlborn framework.
14. Not recovering from UM/UIM. Uninsured and underinsured motorist coverage is treated as third-party recovery subject to DCH lien; do not overlook UM/UIM in personal injury cases.
15. Failing to retroactively address Medicaid eligibility when a settlement is received. Lump sums can trigger immediate termination; consult an elder law attorney before settling.
