Connecticut Form 42: Permanent Impairment Evaluation

Connecticut pays specific (permanency) workers' compensation benefits based on a physician's rating of permanent loss, or loss of use, of a body part once the worker reaches maximum medical improvement. Form 42 is where the Connecticut-licensed physician reports that rating: the body part and side, the standards used, the percentage, the MMI exam date, and any work capacity and restrictions.

Who completes it

A Connecticut-licensed physician completes and signs the evaluation, including the employee's required date of birth. There is no section for the employee or employer to complete.

Submitting and payment

How to submit it
Mail it to all parties: the employee, the insurer and any attorneys. The district office records the date it was filed.
Who pays
The form does not say who pays for the evaluation.

Good to know

  • Use a separate Form 42 for each body part; Connecticut statutes do not recognize whole person ratings (C.G.S. 31-308(b)).
  • Check the box if the rating is the total for that body part, inclusive of any prior ratings.
  • For a hand, arm or thumb mark master or minor; for an eye, indicate complete loss of sight or reduction to one-tenth or less of normal vision.
  • Name the AMA Guides edition or other source used. The current revision is dated 11-3-2023.
