Definition
An In Home Supportive Care Agency provides services in the patient's home with the goal of enabling the patient to remain at home. The services provided may include personal care services such as hands-on assistance with activities of daily living (ADLs), e.g., eating, bathing, dressing, and bladder and bowel requirements; homemaker services and instrumental activities of daily living (IADLs), e.g., taking medications, shopping for groceries, laundry, housekeeping, and companionship; and/or supervision or cuing so that a person can perform tasks themselves.

Where 253Z00000X sits
- Group: Agencies — code 9 of 15 in the group
- Classification: In Home Supportive Care 253Z00000X
In Home Supportive Care has no specializations, so 253Z00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
253Z00000X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — organizations of this type enroll, if at all, under a facility or supplier type rather than a practitioner specialty.

Using 253Z00000X
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.
