Knott County Nursing Home v. Wallen

Summary

The Kentucky Supreme Court held that an administrative law judge may translate a Class 1 through 5 mental impairment under the Fourth Edition of the AMA Guides into a percentage impairment for purposes of calculating permanent partial disability benefits. The court concluded that the absence of percentage ratings for mental impairments in that edition of the Guides did not preclude an award where the mental injury directly resulted from a work-related physical injury. The court affirmed the award based on a 25% impairment rating for the claimant’s mental condition.

Holdings

1. The absence of a percentage impairment rating for mental conditions in the Fourth Edition of the AMA Guides does not preclude a permanent partial disability award for a compensable mental injury that is the direct and proximate result of a work-related physical injury.
2. When a mental injury is at issue, an ALJ is authorized to translate a Class 1 through 5 AMA impairment into a percentage impairment for determining the worker's disability rating and calculating the income benefit under KRS 342.730(1)(b).
3. The ALJ reasonably found that Wallen's mental condition caused a 25% impairment for purposes of KRS 342.730(1)(b).

Questions Presented

1. Whether a claimant may receive permanent partial disability benefits for a work-related mental injury when the applicable edition of the AMA Guides does not assign percentage impairment ratings for mental conditions.
2. Whether an Administrative Law Judge may translate a Class 1 through 5 mental impairment under the Fourth Edition of the AMA Guides into a percentage impairment for calculating benefits under KRS 342.730(1)(b).
3. Whether the ALJ reasonably relied on Dr. Morgan's Class 3 mental impairment assessment and 25% impairment rating.

Disposition

affirmed
