Michigan's Serious Impairment Threshold: When You Can Sue for Pain and Suffering

Michigan pays your medical bills after a crash whether the wreck was your fault or not. That's the no-fault side, and it runs automatically.

Suing the other driver for what the injury actually cost you — the pain, the things you can't do anymore — is a separate case with a separate gate. And most people never learn the gate exists until a lawyer tells them they didn't clear it. For help with a crash claim, see our personal injury practice.

Two different claims, two different rules

Your no-fault (PIP) claim goes to your own insurer. Medical care, wage loss, replacement services. Fault doesn't matter.

Your third-party claim goes against the at-fault driver, and it's where pain-and-suffering damages live. Under MCL 500.3135, you can only bring it if the injury amounts to death, permanent serious disfigurement, or serious impairment of body function.

That last one is where nearly every disputed case lives.

What "serious impairment of body function" means

The statute breaks it into three requirements, and all three have to be met.

It has to be objectively manifested. Observable or perceivable from actual symptoms or conditions by someone other than you. Imaging, clinical findings, documented limitations. This is the requirement that sinks cases built entirely on "my back still hurts" — real pain, but if nothing in the record shows it from the outside, it's hard to prove.

It has to involve an important body function. Not any function — one of real value and significance to you. Courts look at what the function meant to your actual life, which is why the same injury can matter more to one person than another.

It has to affect your general ability to lead your normal life. It must have influenced your capacity to live the way you were living. Not ended it — influenced it.

Michigan's 2019 no-fault reforms wrote the courts' longstanding framework into the statute, which settled years of argument about how strictly to read this. The comparison is your life before against your life after.

The misreadings that cost people cases

"It has to be permanent." It doesn't. There's no requirement that an impairment last a specific length of time. A serious impairment that resolves can still count.

"I went back to work, so I'm fine." Returning to work doesn't end the claim. The question is whether your general ability to live your normal life was affected — not whether you clocked in.

"Nothing was broken." Fractures are easy to prove, not required. Soft-tissue and disc injuries can qualify when the record supports them.

"I felt okay at the scene." Symptoms that appear days later are ordinary. What hurts the claim isn't the delay — it's an unexplained gap where nobody documented anything. This is why seeing a doctor early matters so much.

The exception people miss entirely

The threshold governs noneconomic damages — pain and suffering.

Certain economic losses work differently. Michigan no-fault caps what your own insurer pays, and where your actual losses run past those limits — wage loss extending beyond the no-fault period, medical expense above your coverage level — those excess amounts may be recoverable from the at-fault driver without the same threshold analysis.

So "I don't think I meet the threshold" isn't the end of the conversation. It's the end of one conversation.

What builds the record

Threshold cases are won in the documentation, and most of it is created in the first weeks — long before anyone files anything.

Consistent treatment, with gaps explained rather than left blank. Objective findings, not just reported symptoms. Specific limitations rather than general ones — what you can't lift, how far you can walk, what you stopped doing. And the before-and-after: the league you left, the hobby you dropped, the help you now need at home. That contrast is the whole ballgame on the third element, and nobody reconstructs it well two years later.

Be careful what you say to the other driver's insurer while that record is still forming — a recorded statement taken early, before anyone knows the full extent of an injury, has a way of becoming the version of events you're stuck with.

When to call ELN

If you were hurt in a Michigan crash and you're unsure whether your injuries clear the threshold, that's a question worth asking early — while treatment is ongoing and the record can still be built properly, not after it's closed.

There's also a deadline: a third-party claim generally must be filed within three years of the crash. Waiting doesn't preserve options; it removes them.

ELN Law handles Michigan no-fault and third-party auto claims. Reach out through our personal injury practice or schedule a consultation.
