Definition

A residential treatment facility (RTF) is a facility or distinct part of a facility that provides to children and adolescents, a total, twenty-four hour, therapeutically planned group living and learning situation where distinct and individualized psychotherapeutic interventions can take place. Residential treatment is a specific level of care to be differentiated from acute, intermediate, and long-term hospital care, when the least restrictive environment is maintained to allow for normalization of the patient's surroundings. The RTF must be both physically and programmatically distinct if it is a part or subunit of a larger treatment program. An RTF is organized and professionally staffed to provide residential treatment of mental disorders to children and adolescents who have sufficient intellectual potential to respond to active treatment (that is, for whom it can reasonably be assumed that treatment of the mental disorder will result in an improved ability to function outside the RTF) for whom outpatient treatment, partial hospitalization or protected and structured environment is medically or psychologically necessary

Where 323P00000X sits

Psychiatric Residential Treatment Facility has no specializations, so 323P00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

323P00000X 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 323P00000X

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.
