Ratable Impairments

§ 30.910 Will an impairment that cannot be assigned a numerical percentage using the AMA's Guides be included in the impairment rating?

(a) An impairment of an organ or body function that cannot be assigned a numerical impairment percentage using the AMA's Guides will not be included in the employee's impairment rating.

(b) A mental impairment that does not originate from a documented physical dysfunction of the nervous system, and cannot be assigned a numerical percentage using the AMA's Guides, will not be included in the impairment rating for the employee. Mental impairments that are due to documented physical dysfunctions of the nervous system can be assigned numerical percentages using the AMA's Guides and will be included in the rating.

§ 30.911 Does maximum medical improvement always have to be reached for an impairment to be included in the impairment rating?

(a) An impairment that is the result of a covered illness will be included in the employee's impairment rating determined by OWCP under § 30.901 only if OWCP concludes that the impairment has reached maximum medical improvement, which means that it is well-stabilized and unlikely to improve substantially with or without medical treatment.

(b) Notwithstanding paragraph (a) of this section, if OWCP finds that an employee's covered illness is in the terminal stages, based upon probative medical evidence, an impairment that results from such covered illness will be included in the impairment rating for the employee even if it has not reached maximum medical improvement.

§ 30.912 Can a covered Part E employee receive benefits for additional impairment following an award of such benefits by OWCP?

A covered Part E employee previously awarded impairment benefits by OWCP may file a claim for additional impairment benefits. Such claim must be based on an increase in the impairment rating that is the result of the covered illness or illnesses from the impairment rating that formed the basis for the last award of such benefits by OWCP. OWCP will only adjudicate claims for such an increased rating that are filed at least two years from the date of the last award of impairment benefits. However, OWCP will not wait two years before it will adjudicate a claim for additional impairment that is based on an allegation that the employee sustained a new covered illness.
