Who Pays Your Medical Bills in a Michigan Auto Accident


Steven M. Gursten

Given Michigans complex no-fault auto law, it can be difficult to understand who pays your medical bills when you’re injured in an auto accident. A lot of drivers ask why they have to pay a medical deductible after a car accident, or a medical deductible that is more than $300.

Most people have whats called coordinated or excess medical benefits on their auto insurance policies. This means that in the event the person is injured in a car or a truck accident, his or her health insurance is supposed to pay first, then the auto insurer is responsible for the balance under the Michigan No-Fault law.

There is also an option to have primary medical benefits on your insurance policy. Another term for this is primary medical PIP (personal injury protection benefits). This means that in the event of an auto accident injury, the injured person receives medical benefits from their auto insurance company.

Coordinated coverage is less expensive than primary coverage, as your auto insurance company expects it will not have to pay first in the event of a motor vehicle crash.

However, in some cases, the auto insurer does end up paying first. One such example is if the health insurance policy contains an auto accident exclusion, which is an exclusion in the policy that states the insurance company will not pay for treatment related to auto accidents if there is Michigan No-Fault insurance coverage that applies.

An even more common situation is when people lose their health coverage due to a work layoff or termination and forget to tell their auto insurer that they no longer have health insurance. When this happens, the auto insurer will usually charge a higher medical deductible than it would have had the health insurer been paying first. Most insurers charge anywhere from $0 to $300 for a medical lifetime deductible if the policy is set up correctly. If the insurance company ends up in a primary position, they will increase this amount to $500 or $600 (as an example).


A few unique situations when the above does not apply include GMAC and Medicaid coverage. GMAC Financial Services charges a $2,500 deductible if the insured person was supposed to have primary coverage and did not.

Additionally, Medicare and Medicaid are not supposed to be used for auto accidents, as they are payers of last resort. If an insurance agent asks you if you have other health insurance, remember that Medicare and/or Medicaid do not count. Therefore, you need to have any medical benefits from your auto insurance as primary on your auto insurance policy.

Finally, keep in mind that there can be substantial penalties if someone is using Medicare or Medicaid instead of No-Fault insurance to treat for personal injuries caused by an auto accident. Many medical doctors do not understand this issue, and will simply send bills to Medicare or Medicaid instead of submitting them to a No-Fault insurer as they are supposed to. Please make sure to contact a knowledgeable No-Fault insurance attorney immediately if this happens.

Situations when Michigan drivers should choose primary medical PIP benefits.

There are several situations where its beneficial for people to use medical benefits from their auto insurance by electing to have primary medical PIP coverage. Even though it may be a little more expensive, the positives far outweigh the slightly higher costs.

Here are a few examples of when people are better off with primary medical PIP insurance benefits:

1. Auto Accident Exclusions

If you have any type of auto accident exclusion in your health insurance policy, you should elect primary medical on your auto No-Fault insurance. To find out whether you have an auto accident exclusion, you should contact your health insurer and request a copy of the summary plan description or the plan itself. Review this with your insurance agent as well. Heres some info on how to read your auto insurance policy.

2. Beware of ERISA plans

If your health insurance is a self-funded ERISA plan, you should elect primary medical on your auto No-Fault insurance. These plans can claim a federal lien against your auto accident negligence case (your case for pain and suffering after a car accident). Keep in mind, this area of law is continually changing and is being strongly contested between personal injury lawyers and consumer justice organizations on the one hand, and lawyers representing the ERISA plans on the other. The best way to avoid the problem is to elect primary medical on your auto No-Fault insurance.

3. If you have an HMO

HMOs can be very restrictive and can often result in delayed medical treatment. By electing primary medical PIP, you do not have to treat within the HMO and can substantially expedite your treatment and improve your choice of providers.

4. Important Warning about Medicare and Medicaid if you are injured in a car accident and have Michigan No-Fault insurance:

If you have Medicare, Medicaid, Veterans Administration Benefits or any county health plan, you should have primary medical PIP on your auto No-Fault insurance. This helps to avoid the super liens that providers of government benefits may otherwise have against your automobile negligence case (the case for your personal injuries and pain and suffering that you would bring against the person who has caused your accident).

5. Blue Cross Blue Shield

Be aware that there is the possibility of a double dip if you have traditional Blue Cross and full coverage on your No-Fault insurance policy. For this reason alone, anyone with Blue Cross Blue Shield should have primary No-Fault auto insurance as well

If you have health insurance (other than Medicare or Medicaid) and you want to save money on your auto insurance, you have the option in Michigan to buy coordinated/excess medical PIP coverage. This coordinated policy puts your health insurance in a primary position to your car insurance for auto accident-related medical expenses. Most insurers today already default to coordinated/excess medical, but some agents never ask if you already have health insurance.

If you lose your health insurance for any reason, or you have a situation as noted above, you should immediately contact your auto insurer and change to primary medical coverage.
