Under the Texas Workers’ Compensation system, a worker will reach Maximum Medical Improvement when based on reasonable medical probability, further material recovery from or lasting improvement to an injury can no longer reasonably be anticipated. Generally this must happen no later than 104 weeks from the date that benefits begin to accrue.
Texas currently uses the 4th Edition of the Guides to the Evaluation of Permanent Impairment. The Guides provide the manner for a doctor to calculate the injured workers’ Impairment Rating. The rating will will be no impairment or a finding from 0% to 100% whole body impairment rating.
To do a proper rating, the doctor must address each compensable condition and provide a rating for that condition. All conditions are added to provide the whole body impairment rating.
