Definition
The Defense Health Program or U.S. Coast Guard funded "fixed" facilities or distinct parts of a facility, providing outpatient medical and dental services, primarily for Uniformed Services beneficiaries. A "fixed" facility is a non-temporary, non-deployed facility. It includes mobile specialty units such as Magnetic Resonance Imaging (MRI) units that may furnish services at the "fixed" facility. It includes, as examples, the institutional portion of outpatient encounters (except Ambulatory Procedure Visits), supplies issued (e.g., glasses, ostomy supplies, crutches), and radiology and laboratory studies. Does not include items issued directly to a patient from an outpatient pharmacy or patient transport.

- Classification: Clinic/Center 261Q00000X
- Specialization: Military/U.S. Coast Guard Outpatient 261QM1100X
Choose 261QM1100X over the general Clinic/Center code (261Q00000X) when the provider's training or certification is specifically in military/u.s. coast guard outpatient; 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
261QM1100X 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.

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.
