What is MMI?

“MMI” is an acronym for Maximum Medical Improvement.  It is seldom used by doctors unless they are treating or evaluating a Workers’ Compensation Claimant.  Practically, MMI is a delineation point in time within the context of a Workers’ Compensation case, recognized as such by Insurance Companies, WC Judges, and the lawyers.  It is common that the patient, the WC Claimant, disagrees.  Although the determination of MMI may be contested based on other medical evidence, it generally means the end of the healing period, therefore the end of TTD weekly benefits. Determination of MMI, which is entered in a written medical report, may be asserted as a defense to further or future medical benefits.  Once a claimant reaches MMI, he may be required to prove entitlement to further reasonable and “necessary”  medical treatment, and as TTD has ended a permanent impairment must be proved in order for the Claimant to receive further indemnity (monetary) benefits, or very much by way of a settlement.
             If a Claimant has significant undiagnosed medical problems or compensable consequences arising from the original injury, outside evidence must be sought. Without the help of a lawyer, you are less likely to go about this in an effective way, and if you wait until you first hear MMI to do something your odds are diminished.
