What Happens When You Reach Maximum Medical Improvement (MMI) in Vermont?

Receiving a letter from a workers' compensation insurance adjuster stating that you have reached 'Maximum Medical Improvement'-often called a 'medical end result' in Vermont-can trigger immediate financial panic if you are still in daily pain and unable to perform your old job in Burlington, Rutland, or Montpelier. Many injured workers mistakenly believe that MMI means their doctor thinks they are completely healed or that their right to medical treatment is over. In reality, MMI is a specific legal milestone that restructures how the insurance carrier pays you.

Under Vt. Workers' Comp. R. 2.1200 and 21 V.S.A. § 642, MMI-defined by rule as an 'End Medical Result'-simply means your injury has reached a substantial plateau where further surgical or restorative treatment is no longer reasonably expected to significantly improve your underlying medical condition. Reaching this plateau allows the insurer to transition your weekly checks from Temporary Total Disability (TTD) to Permanent Partial Disability (PPD) under 21 V.S.A. § 648, while leaving your right to ongoing palliative medical care-such as pain management, hardware removal, or prescription medications-fully intact under 21 V.S.A. § 640.

The Legal Transition From TTD Benefits to Permanent Partial Disability (PPD)

How Insurers Terminate Temporary Checks Using Form 27

An insurance company in Vermont cannot simply stop mailing your weekly TTD or Temporary Partial Disability (21 V.S.A. § 646) checks the day an Independent Medical Examiner claims you reached MMI. Unless you have successfully returned to work, 21 V.S.A. § 643a requires the insurer to notify both you and the Vermont Department of Labor, Workers' Compensation Division, Montpelier at least 7 days in advance by filing Form 27, Vermont, Department of Labor, Notice of Intention to Discontinue Payments, accompanied by the specific medical records supporting the MMI determination. If the Department determines that the insurer's medical evidence does not reasonably support discontinuance, it will reject the Form 27 and order your temporary checks to continue.

How Permanent Partial Disability (PPD) Weeks Are Calculated in Vermont

Once TTD payments legitimately end at MMI, any lasting loss of physical function entitles you to Permanent Partial Disability (PPD) benefits under 21 V.S.A. § 648. Importantly, PPD benefits are paid in addition to the TTD benefits you already received, with zero deduction for prior temporary checks. Vermont uses two distinct statutory multipliers depending on the injured anatomy:

How Impairment Ratings Are Assigned Using the AMA Guides in Vermont

Mandatory Use of the AMA Guides Fifth Edition

Under 21 V.S.A. § 648(b), all permanent impairment ratings in Vermont must be calculated as a 'whole person impairment' percentage strictly in accordance with the Fifth Edition of the American Medical Association (AMA) Guides to the Evaluation of Permanent Impairment. Unlike states that switched to the Sixth Edition (which drastically reduced ratings for surgical disc herniations and joint replacements), Vermont's adherence to the Fifth Edition allows physicians to evaluate spinal injuries using either the Diagnosis-Related Estimate (DRE) method or the Range-of-Motion (ROM) method when multilevel pathology or recurrent radiculopathy is present.

Keep in mind what an AMA Guides rating measures-and what it ignores. As the Vermont Supreme Court explained in Bishop v. Town of Barre, 140 Vt. 564 (VT Supreme Court 1982), permanent partial disability under 21 V.S.A. § 648 compensates for anatomical functional impairment rather than individual wage loss, though the Commissioner retains discretion to weigh competing medical opinions when two doctors assign different percentages. Furthermore, under 21 V.S.A. § 648(d), an insurer can only automatically apportion (subtract) a pre-existing condition from your impairment rating if that prior injury to the same body part was previously both rated and paid.

Step-by-Step Process: What to Do If You Disagree With an MMI Determination

Step 1: Object to the Form 27 Discontinuance Notice Immediately

When an insurance carrier hires an Independent Medical Examiner (IME) under 21 V.S.A. § 655 who claims you have reached MMI prematurely-while your treating surgeon in Burlington or Lebanon is still recommending injections, physical therapy, or surgery-act immediately. Contact the Workers' Compensation Specialist at the Vermont Department of Labor, Workers' Compensation Division, Montpelier and file Form 6, Vermont, Department of Labor, Notice and Application for Hearing alongside your treating doctor's progress notes showing that active treatment will still improve your function.

Step 2: Obtain an Independent Impairment Rating at the Insurer's Expense

Never sign Form 22, Vermont, Department of Labor, Agreement for Permanent Partial or Permanent Total Disability Compensation based solely on the insurance company's IME doctor. Under Vt. Workers' Comp. R. 11.2400, the employer or insurer is legally required to pay for at least one permanency examination and impairment rating performed by your own treating physician, even if the insurer already paid its own IME doctor for a rating. If your treating doctor's rating is 14% and the insurer's IME doctor says 6%, an experienced attorney can negotiate a split or take the dispute to a hearing.

Step 3: Demand Vocational Rehabilitation If You Cannot Return to Your Old Job

If reaching MMI leaves you with permanent lifting or standing restrictions that prevent you from returning to your prior occupation, 21 V.S.A. § 641 entitles you to Vocational Rehabilitation services-including skills retraining, tuition assistance, and job placement-when you are unable to return to suitable employment using your existing skills.

Step 4: Choose Between Weekly PPD Checks, Form 22, or a Form 16 Lump Sum

Once your final impairment percentage is agreed upon or ordered, you will execute Form 22, Vermont, Department of Labor, Agreement for Permanent Partial or Permanent Total Disability Compensation. Signing a Form 22 does not close your future medical benefits and allows you to seek modification of your award if your condition worsens within 6 years of the date of the award (21 V.S.A. § 668). Under 21 V.S.A. § 652, you may request that your Form 22 PPD benefits be paid in a single lump sum rather than weekly installments. By contrast, signing a full and final Form 16, Vermont, Department of Labor, Settlement Agreement permanently closes disputed indemnity or medical portions of your claim in exchange for a negotiated cash buyout approved by the Commissioner.

How Much Does It Cost to Challenge MMI or a Low Rating in Vermont?

• Attorney Fees: Contingency fees are capped under Vt. Workers' Comp. R. 20 at 20% of disputed benefits recovered, and if you win at a formal hearing, the Commissioner can order the insurer to pay your attorney's fees and expert medical deposition costs under 21 V.S.A. § 678.
