Where 261QM2500X sits
- Group: Ambulatory Health Care Facilities — code 27 of 63 in the group
- Classification: Clinic/Center 261Q00000X
- Specialization: Medical Specialty 261QM2500X
Choose 261QM2500X over the general Clinic/Center code (261Q00000X) when the provider's training or certification is specifically in medical specialty; 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.
Medicare
261QM2500X 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 261QM2500X
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.
