MMI Letter Template: Documenting Maximum Medical Improvement
Introduction: Reaching the Plateau
Maximum Medical Improvement (MMI) is a pivotal concept in injury cases. It signifies that a patient has recovered as much as they are going to. The MMI Letter communicates this status to insurers and lawyers, effectively transitioning a case from active treatment to settlement or maintenance.
Why an MMI Letter is Essential
This document drives the legal and financial resolution of a claim:
- Claim Resolution: Signals that temporary total disability (TTD) payments may end and permanent partial disability (PPD) assessment begins.
- Impairment Rating: Provides the percentage of impairment (if any) used to calculate settlement values.
- Future Care: Outlines what ongoing medical needs (e.g., meds, annual checks) the insurer is liable for.
- Legal Compliance: Meets strict statutory requirements for reporting in workers' compensation systems.
Key Components of an MMI Report
A complete MMI report must include:
- MMI Date: The effective date the patient reached stability.
- Diagnosis/Treatment Summary: Brief recap of the injury and care provided (e.g., surgery, PT).
- Current Status: Objective findings (ROM, strength) keeping the patient from full recovery.
- Permanent Impairment Rating (PIR): Calculated per the AMA Guides (e.g., "5% Whole Person Impairment").
- Permanent Restrictions: Long-term limitations (e.g., "No lifting > 50lbs").

Q: What is Maximum Medical Improvement (MMI)?
It is the point where an injured person's condition has stabilized, and no further significant improvement is expected, even with additional treatment.
Q: Does MMI mean I am 100% cured?
No. It simply means your condition has plateaued. You may still have pain, limitations, or disability.
Q: Who determines when MMI is reached?
The treating physician makes this clinical determination based on your response to treatment and objective findings.
Q: What happens after MMI?
Your case typically shifts from temporary benefits to determining permanent disability (if any) and settlement negotiations.
Q: What is an Impairment Rating?
A percentage assigned to body parts or the 'whole person' (based on AMA Guides) indicating the severity of permanent loss of function.
Q: Can I get treatment after MMI?
Yes, 'palliative' or maintenance care (like occasional PT or meds) to keep the condition from worsening is often allowed.
Q: What if I disagree with the MMI finding?
You can request a second opinion or an Independent Medical Examination (IME) to challenge the finding.
Q: Are MMI letters used in court?
Yes, they are core evidence in workers' compensation and personal injury litigation to establish damages.
Q: How do HealOS agents help with MMI?
They automate the compilation of treatment history and facilitate the drafting of the detailed MMI report, ensuring accuracy.
Q: How is impairment calculated?
Physicians use standardized guides (like the AMA Guides to the Evaluation of Permanent Impairment) to calculate the rating.
