Medical Impairment Rating (MIR) Registry
The Medical Impairment Rating (MIR) Registry is a Bureau of Workers' Compensation-maintained listing of qualified and approved physicians who are specially trained to conduct impairment rating medical evaluations and who have applied to serve on the Registry.
The program is designed to assist parties in settling a workers' compensation claim when the only item being disputed is the impairment rating.
The program is available only for dates of injuries on/after July 1, 2005.
Request Dispute Resolution
To request the MIR evaluation by a registered physicians, one of the parties must submit an Application for a Medical Impairment Rating (MIR) form to the Bureau. But, before the parties can request a MIR evaluation, there must be a dispute about the current impairment rating.
Submit MIR Requests to Jay.Blaisdell@tn.gov or 615-253-5263
A dispute occurs when:
- There are competing impairment ratings issues by different physicians, and the parties disagree as to which rating is correct (dueling doctors), or
- The treating physician has placed permanent restrictions on the claimant, but has issued a rating of "zero," or states that there is "no permanent impairment," or
- The employer and employee both wish to access the Medical Impairment Rating Registry because they agree that the permanent medical impairment rating issued by the authorized treating physician is incorrect.

How it works
The program provides the names of physicians, listed on the Registry, who are specifically trained in the techniques of performing impairment rating evaluations on the body part(s) involved in the workers' compensation claim. The parties choose a physician from the list provided to perform an evaluation to determine an appropriate impairment rating. The rating produced is utilized to help determine any Permanent Disability Benefits due in the matter. An MIR evaluation may be requested by either party. Regardless of which party requests it, the cost of the evaluation is borne by the employer. The report provided by the MIR physician will provide only the impairment rating. It will not address causation, apportionment, job restrictions or modifications, or the appropriateness of treatment.
Accurate, Objective, Impartial
Unlike most other physicians who practice within the Tennessee workers’ compensation system, MIR Physicians are formally trained to conduct impairment evaluations according to the AMA Guides. They are also required to cite the AMA Guides in their reports to show exactly how their impairment rating was obtained. Since the MIR Physician has no affiliation with either the employer or employee, and neither party may communicate with the MIR Physician prior to the evaluation, the whole process is designed to be objective and impartial. Once the MIR Report is completed, it is submitted to another independent physician for “peer review” to ensure AMA Guides methodology has been properly applied. Finally, and most importantly, MIR Reports are legally presumed to be accurate. Since a much higher standard of evidence must be used to refute an MIR Report, they usually supersede all other impairment rating opinions.
Impairment Ratings: by the book
Injuries occurring on or after January 1, 2008 must be rated by the AMA Guides to the Evaluation of Permanent Impairment, 6th Edition. Injuries occurring prior to January 1, 2008, must be rated by the applicable version of the AMA Guides, as determined by the Tennessee Workers' Compensation Act.
