Definition
A psychologist who specializes in the study and application of psychological principles on behalf of persons who have disability due to injury or illness. Rehabilitation psychologists, often within teams, assess and treat cognitive, emotional, and functional difficulties, and help people to overcome barriers to participation in life activities. Rehabilitation psychologists are involved in practice, research, and advocacy, with the broad goal of fostering independence and opportunity for people with disabilities.

Choose 103TR0400X over the general Psychologist code (103T00000X) when the provider's training or certification is specifically in rehabilitation; the general code covers the classification as a whole. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Using 103TR0400X
The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
