Medicare does cover auto accident injuries in Michigan, but only as a secondary payer behind your no-fault auto insurance. Federal law requires your Personal Injury Protection (PIP) medical coverage to pay first for crash-related care, and Medicare picks up eligible costs after that. If you’ve used Michigan’s 2019 reform to opt out of PIP medical coverage entirely, Medicare becomes your main source of accident coverage, and its limits and exclusions can leave you paying large bills out of pocket.1Office of the Law Revision Counsel. 42 USC 1395y: Exclusions From Coverage and Medicare as Secondary Payer
PIP Pays First, Medicare Pays Second
Michigan requires every driver to carry no-fault auto insurance that includes PIP medical coverage. When you’re injured in a crash, your PIP policy pays your medical bills regardless of fault. If you also have Medicare, the two coordinate: PIP handles the bills up to your chosen coverage level, and Medicare covers eligible costs after that.2State of Michigan. Frequently Asked Questions
Medical providers must bill your auto insurer first. If a bill goes to Medicare while PIP is available, the federal government will seek repayment. The rule is the same whether you have Original Medicare or a Medicare Advantage plan.3Medicare.gov. How Medicare Works With Other Insurance
The Medicare Opt-Out After Michigan’s 2019 Reform
Before July 2020, every Michigan auto policy came with unlimited lifetime PIP medical coverage. The 2019 no-fault reform introduced tiered choices under MCL 500.3107c. When you buy or renew a policy today, you pick from unlimited coverage, $500,000 per person per accident, $250,000 per person per accident, or a complete opt-out reserved for Medicare beneficiaries. A separate $50,000 tier exists but is only available to Medicaid enrollees, not Medicare enrollees.4Michigan Legislature. MCL 500-3107c
Who Qualifies for the Opt-Out
To drop PIP medical coverage entirely, you must be enrolled in both Medicare Part A and Part B. Every other person in your household, including your spouse and any relatives living with you, must have their own auto insurance policy or other qualifying health coverage. Your insurer will ask for proof of Medicare enrollment, usually a copy of your Medicare card or a benefit verification letter, and you’ll re-verify at each renewal. If you can’t provide proof, the insurer must issue your policy at the highest available coverage level.5State of Michigan. Quick Facts: Automobile Insurance for Seniors
If you lose Medicare enrollment while your opt-out is in effect, you have 30 days to get a new policy with PIP medical coverage. Missing that window can leave you personally responsible for all medical costs if you’re in a crash during the gap.6Michigan Legislature. SB 1 – Summary as Enrolled
Where Medicare Falls Short After a Serious Crash
Medicare covers hospitalization, doctor visits, and many rehabilitation services, but it was never built to replace no-fault benefits. A full PIP policy pays for categories of care and non-medical costs that Medicare either caps sharply or excludes entirely.
Skilled Nursing Facility Stays Are Capped at 100 Days
Medicare Part A pays for skilled nursing facility care only after a qualifying hospital stay of at least three consecutive days, and only for up to 100 days per benefit period. The first 20 days are fully covered after you meet the $1,736 deductible in 2026. From day 21 through day 100, you pay a $217 daily coinsurance. After day 100, Medicare pays nothing.7Medicare.gov. Skilled Nursing Facility Care A severe crash requiring months of rehabilitation can run past those limits. An unlimited PIP policy covers reasonable and necessary care for life.
No Long-Term Custodial Care
Medicare does not cover custodial care, meaning ongoing help with daily activities like bathing, dressing, and eating that doesn’t require skilled medical treatment. If a crash leaves you needing permanent assistance in a residential facility, Medicare won’t pay for it. Michigan PIP policies at the higher coverage tiers generally do cover this kind of long-term care when it results from an auto accident.
Attendant Care and Home Health Aides
Michigan no-fault policies often pay for in-home attendant care, whether provided by professional aides or by family members, so injured residents can stay in their homes rather than move to a facility. Medicare generally does not cover non-medical home assistance. Hourly rates for home health aides typically run from about $11 to $21, and someone needing round-the-clock help can face costs exceeding $100,000 per year.
Home and Vehicle Modifications
Wheelchair ramps, widened doorways, hand controls for driving, and other accessibility modifications fall under Michigan PIP but not under Medicare. Permanent wheelchair ramps typically run from $1,100 to over $6,000, and vehicle hand controls range from a few hundred dollars for basic equipment to several thousand for more advanced systems. Without PIP coverage, these costs are yours.
Wage Loss and Household Services
PIP goes beyond medical bills. A Michigan no-fault policy covers lost wages for up to three years after an accident and pays for household services you can no longer perform, such as cleaning or yard work.8Michigan Department of Insurance and Financial Services. Brief Explanation of Michigan No-Fault Insurance Medicare provides neither. Opting out of PIP medical coverage costs you these non-medical benefits too.
Cost-Sharing on the Bills Medicare Does Cover
Even for covered services, you owe cost-sharing. The 2026 Part B annual deductible is $283, and you generally owe 20 percent coinsurance for outpatient services after meeting the deductible.9Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles After a major accident with surgery, imaging, and months of therapy, that 20 percent adds up.
Medicare Advantage and Medigap Follow the Same Rules
A Medicare Advantage plan (Part C) sits in the same secondary position as Original Medicare. Auto insurance pays first, and the Advantage plan pays second for remaining eligible costs. If the plan makes a conditional payment on an accident claim, it will investigate and seek repayment the same way Original Medicare would.3Medicare.gov. How Medicare Works With Other Insurance
Medigap (Medicare Supplement Insurance) pays after Medicare, placing it third in line behind your auto policy and Medicare. When Medicare acts as secondary payer, Medigap can help with the deductibles and coinsurance Medicare leaves behind.10Centers for Medicare & Medicaid Services. Medicare Secondary Payer
Conditional Payments and Repayment
If your auto insurer denies a claim or delays paying, Medicare may pay your accident-related bills on a conditional basis so you aren’t left without care during the dispute. These payments are essentially a loan. Medicare expects repayment once your auto insurer pays or a legal settlement is reached, and the federal government tracks every dollar it spends on your accident-related treatment.11Centers for Medicare & Medicaid Services. Coordination of Benefits and Recovery Overview
You’re legally required to tell Medicare about any pending claims or lawsuits that could result in a recovery. When a case approaches settlement, notice goes to the Benefits Coordination and Recovery Center (BCRC) at least 120 days before the anticipated settlement date. The BCRC issues a conditional payment letter listing accident-related charges, and you can dispute items that aren’t crash-related, such as a routine check-up that happened during the same period.12Centers for Medicare & Medicaid Services. Medicare’s Recovery Process
After settlement, the BCRC issues a formal demand for repayment. You have 60 days to pay in full before interest begins to accrue.13Centers for Medicare & Medicaid Services. How Interest Is Calculated Unresolved debts 150 days after the demand letter can be referred to the U.S. Treasury for collection. The final amount may be reduced under a federal formula that accounts for attorney fees and court costs, so you aren’t repaying more than your net recovery.
Choosing a Coverage Level That Fits
The premium savings from opting out of PIP medical coverage can look attractive, but the financial exposure after a serious crash is significant. Michigan’s no-fault system was built around the idea that auto insurance, not health insurance, handles accident injuries. Medicare’s caps on skilled nursing, its exclusions for custodial care, attendant care, home modifications, and wage loss, and its cost-sharing on the services it does cover leave real gaps. Before you opt out, confirm that everyone in your household has independent coverage and be clear about what you’re giving up: not just emergency care, but long-term rehabilitation, in-home assistance, accessibility modifications, and up to three years of wage replacement.
