Section 20-2-VII - MAXIMUM MEDICAL IMPROVEMENTA. When an employee has reached maximum medical improvement (MMI) for the work related injury and/or illness, the physician should promptly, and at least within fourteen (14) calendar days, submit a report to the payer showing the date of maximum medical improvement (MWCC Form B9,27). B. Maximum medical improvement is reached at such time as the patient reaches the maximum benefit from medical treatment or is as far restored as the permanent character of his injuries will permit and/or the current limits of medical science will permit. Maximum medical improvement may be found even though the employee will require further treatment or care. The CMS-1500 form will be accepted in lieu of the Commission form if appropriate office/progress notes are attached.20 Miss. Code. R. § 2-VII
