Reaching Maximum Medical Improvement (MMI) — What It Means for Your Claim

What MMI Actually Means

Maximum medical improvement is the point at which your treating doctor determines your condition has stabilized — further treatment isn't expected to significantly improve it. This is a specific medical and legal determination, not just a general sense that you're "better."

MMI Doesn't Mean Fully Recovered

You can reach MMI while still having lasting symptoms or limitations. MMI means the improvement has plateaued, not that the injury is resolved. Some workers reach MMI with no lasting impairment; others reach it with a permanent, ongoing limitation — both are still "MMI."

Why This Point Matters So Much

Until you reach MMI, you're generally in temporary disability status, and a firm settlement value usually can't be calculated. Once you reach MMI, if any permanent impairment remains, your doctor assigns an impairment rating, which is what actually drives the permanent disability portion of a settlement.

Who Determines MMI

Typically your treating physician, though an insurer can request an independent medical examination (IME) to get a second opinion if they disagree with your doctor's assessment — and in some states, disputes over MMI status go through a specific evaluator system.

What Happens Around MMI

• Temporary disability benefits typically end or transition once MMI is reached
• Your permanent impairment rating (if any) gets assigned
• Settlement negotiations, if applicable, usually begin in earnest around this point
• Return-to-work discussions intensify, based on whatever permanent restrictions remain

If you disagree with an MMI determination — either that you've reached it prematurely, or that your impairment rating doesn't reflect your actual condition — this is a common and legitimate basis for dispute, not something you're stuck accepting without question.
