Definition
Occupational therapists work with older adults in virtually every setting: assisted living, wellness programs, hospitals, nursing homes, senior centers, clinics and in the home. Occupational therapists bring an understanding of the importance of participation and occupation for overall well-being to those who are experiencing disabling conditions related to aging. The primary overarching goal of occupational therapy services with this population is to maximize independence and participation, thereby enabling an older person to continue to live successfully in his or her chosen environment. Occupational therapists can help older adults by developing strategies to help or maintain safety and well-being, to assist with life transitions, and to compensate for challenges they experience in activities of daily living, instrumental activities of daily living, leisure participation, social participation, and productive activities.

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.
