NON-AVAILABILITY STATEMENT (NAS)

A Non-Availability Statement (NAS) is required before any non-emergent inpatient services may be provided to a TRICARE beneficiary by a non-Military Treatment Facility (MTF). The NAS is issued at the discretion of the MTF Commander. It is valid for 30 days after the date of issuance for the specific reason requested and obtained. The NAS remains valid from the date of admission until 15 days after discharge for follow-up treatment related to the admission stay.
