Welcome back to our 26 in '26 Blog Series. Each post will address a top-of-mind topic in the clinical evaluation services sector. In the previous post, we discussed Jurisdictional Rules. This is the thirteenth post in our series and will detail Maximum Medical Improvement.
Maximum Medical Improvement (MMI) is one of the most influential—and most misunderstood—determinations in medical-legal claims. MMI does not mean the individual is fully healed, pain-free, or returned to baseline. It means the condition has reached a point of medical stability where further substantial improvement is not reasonably expected with additional treatment.
MMI drives critical downstream decisions, including benefit duration, permanent impairment ratings, settlement posture, vocational planning, and return-to-work strategy. When MMI is unclear or poorly explained, disputes escalate, and claims stall.
A defensible MMI analysis evaluates the full course of treatment, the response to care, and whether additional interventions are likely to materially improve function. Time alone does not establish MMI, nor does frustration with prolonged treatment.
Independent Medical Exams (IMEs) are often best positioned to determine MMI because they combine record review with a current examination and functional assessment. Peer Reviews also contribute by identifying when care has plateaued and shifted from restorative to maintenance.
Functional Capacity Exams may show stable functional performance across repeated testing, supporting MMI conclusions. Fitness-for-Duty exams may intersect once safety-based capacity has stabilized, even if symptoms persist.
MMI does not preclude future care. Post-MMI treatment may still be appropriate for symptom management or maintenance; the key distinction is whether care is expected to change functional status.
Best Practice
Require MMI opinions to explain the rationale: what treatment was tried, what response occurred, and why further care is or is not expected to materially improve function.
