Medicare Plans and Coverage in Michigan

Michigan has approximately 2 million Medicare beneficiaries, with more turning 65 each year than nearly any other state. Michigan's 2026 Medicare market includes Original Medicare, dozens of Medicare Advantage plans, a regulated Medigap market with a unique Michigan advantage, and a strong free counseling network (MMAP) that most seniors underuse.

This guide covers the main Michigan-specific details for 2026: plan options, how Medigap works differently in Michigan, and how to get free help picking a plan.

The Four Parts of Medicare

Part A (Hospital)

Covers inpatient hospital, skilled nursing facility (post-hospital), hospice, and limited home health.

2026 costs for most beneficiaries:

• Premium: $0 for most (those who paid Medicare taxes for 10+ working years)
• Inpatient deductible: ~$1,700 per benefit period (verify 2026 figure)
• SNF coinsurance: $0 days 1-20, then approximately $214/day for days 21-100 in 2026

Part B (Medical)

Covers doctor visits, outpatient hospital, preventive care, DME.

2026 standard premium: approximately $185/month (higher for high-income beneficiaries under IRMAA). Annual deductible: approximately $257 in 2026. Coinsurance: 20% after deductible for most services.

Part D (Prescription Drugs)

Covers outpatient prescription drugs. Sold separately by private insurers.

2026 key changes: New $2,000 annual out-of-pocket cap for all Part D beneficiaries (implemented under the Inflation Reduction Act). Significantly improves drug affordability for high-cost seniors.

Part C (Medicare Advantage)

All-in-one plans that bundle Parts A, B, and typically D, often with additional benefits (dental, vision, hearing, gym, OTC allowance). Operated by private insurers.

Michigan's 2026 Medicare Advantage Market

Michigan has dozens of MA plan options in 2026. Major carriers include:

• HAP (Health Alliance Plan): Detroit-based, strong in SE Michigan.
• Priority Health: Grand Rapids-based Spectrum Health affiliate, strong in West Michigan.
• Blue Cross Blue Shield of Michigan / Blue Care Network: statewide dominant insurer.
• United Healthcare: national, broad Michigan footprint.
• Humana: national, strong rural Michigan presence.
• Aetna: national.
• WellCare: Centene affiliate.
• Molina: primarily Medicaid, also MA.
• McLaren Health Plan: McLaren Healthcare affiliate.
• Physicians Health Plan: local/regional.

Plan availability, networks, and benefits vary by county. Check medicare.gov's Plan Finder for your specific ZIP code.

Michigan Medigap: The Birthday Rule Advantage

Medigap (Medicare Supplement) plans fill in Original Medicare's cost-sharing gaps. Michigan has a regulatory advantage most states don't offer:

The Michigan Medigap "Birthday Rule" allows Medicare beneficiaries to switch to an equal-or-lesser Medigap plan of the same letter with a different insurer during a 30-day window starting 30 days before their birthday each year. During this window:

• No medical underwriting: the new carrier must accept the member.
• No rate-up for age or health.
• Same or better plan letter only (you can't jump from Plan N to Plan G under this rule).

This is a meaningful consumer protection. In many states without the Birthday Rule, once you select a Medigap plan, you can only switch without underwriting during the initial 6-month open enrollment at age 65. After that, pre-existing conditions can block or price-up plan switches.

In Michigan, you can shop every birthday.

Standard Medigap Plans in Michigan

Federal law standardizes Medigap plans into lettered categories (A, B, C, D, F, G, K, L, M, N). Most popular:

• Plan G: Comprehensive coverage (covers everything except Part B deductible). 2026 premiums in Michigan typically $150-$200/month for new 65-year-olds, higher for older enrollees.
• Plan N: Lower-premium option with some small copays. Commonly $110-$150/month.
• Plan F: Grandfathered for people Medicare-eligible before 2020; covers everything including Part B deductible. No longer sold to new enrollees.
• High-Deductible Plan G: Lowest premium; high deductible before full coverage kicks in.

BCBSM is the dominant Medigap carrier in Michigan; several others compete on price and service.

Part D in Michigan

Standalone Part D prescription drug plans are offered by many carriers. 2026 national lows: premiums as low as $0/month for select plans. Michigan-specific picks depend on:

• Your specific medications and whether they're on the plan's formulary.
• Your preferred pharmacy (in-network vs. standard).
• Total annual cost factoring premium + deductible + copays, not just premium alone.

The 2026 $2,000 Part D out-of-pocket cap (under the Inflation Reduction Act) is a major benefit. Insulin is capped at $35/month. These apply across all plans.

Special Needs Plans (SNPs)

Three types exist in Michigan:

• Chronic-condition SNPs (C-SNP): for people with specific conditions (diabetes, heart disease, etc.).
• Institutional SNPs (I-SNP): for long-term nursing facility residents.
• Dual-eligible SNPs (D-SNP): for people with both Medicare and Medicaid.

For Michigan duals specifically, MI Coordinated Health (MICH) launched January 1, 2026 as a HIDE SNP variant that integrates Medicaid (including LTSS) more tightly than a standard D-SNP. See the MI Coordinated Health guide.

Enrollment Periods

Low-Income Help

For Medicare beneficiaries with limited income and resources, multiple programs reduce costs:

Medicare Savings Programs (MSPs): Medicaid pays some or all of Medicare's out-of-pocket costs:

• QMB: pays Part A and B premiums, deductibles, and coinsurance for income up to 100% FPL.
• SLMB: pays Part B premiums, for income 100-120% FPL.
• QI: pays Part B premiums, for income 120-135% FPL.

Extra Help (Low Income Subsidy, LIS): reduces Part D prescription drug costs for income up to 150% FPL.

Apply for both through MI Bridges or a county MDHHS office. See our Michigan Medicaid Programs hub.

MMAP: Free Medicare Counseling in Michigan

Michigan's State Health Insurance Assistance Program (SHIP) is called MMAP: Medicare/Medicaid Assistance Program. MMAP is:

• Free.
• Neutral (not affiliated with any insurance carrier).
• Certified by MDHHS and trained annually on Medicare changes.
• Operated through the 16 Area Agencies on Aging.

MMAP counselors help with:

• Picking a Medicare Advantage, Medigap, or Part D plan.
• Comparing costs.
• Applying for Low-Income Subsidy and Medicare Savings Programs.
• Appealing coverage denials.
• Navigating MI Health Link / MI Coordinated Health transitions.

Call MMAP: 1-800-803-7174.

Using MMAP before talking to an insurance broker typically saves money and prevents manipulation into high-commission plans that don't actually fit.

Coordinating Medicare with Other Coverage

Many Michigan seniors have multiple coverage types:

Medicare + Employer Coverage: If still working and the employer has 20+ employees, employer coverage is typically primary. At retirement, sign up for Part B without penalty (8-month Special Enrollment Period after employment ends).

Medicare + Veteran Affairs (VA): Medicare and VA can both provide services, but VA-provided care doesn't go through Medicare. Enroll in VA through the VAMC; consider Part D if taking medications outside the VA formulary.

Medicare + Medicaid (dual eligibles): Medicaid pays Medicare cost-sharing through MSPs; may also enroll in MICH for integrated care.

Medicare + TRICARE for Life: Retirees of the military get TRICARE coverage that works alongside Medicare.

Common Misconceptions

"Medicare is free." Part B premiums apply for most beneficiaries. Part D premiums and cost-sharing apply. Medigap plans cost $100-$300/month for most.

"Medicare Advantage is always cheaper than Original Medicare + Medigap." Not always. MA has low premiums but higher per-service copays; Medigap has higher premiums but covers nearly all costs. Run the math for your situation.

"I can switch Medigap plans anytime." In most states, once past initial enrollment, Medigap underwriting applies for switches. In Michigan, the Birthday Rule lets you switch annually without underwriting within 30 days of your birthday: a meaningful advantage.

"The Plan Finder on Medicare.gov gives me the best plan automatically." It compares plans on selected criteria but doesn't always surface the best fit for your situation. MMAP counseling layers in context the tool can't capture.

"I don't need Part D if I'm healthy." Without Part D, a prescription need later triggers a late enrollment penalty of 1% per month delayed, added permanently to your premium. Even low-cost Part D plans avoid this.
