Indian Health Service (IHS) Rural Emergency Hospital (REH)
10.2.1.8.1.1 – Indian Health Service (IHS) Rural Emergency Hospital (REH)
(Rev. 12217; Issued: 08-24-23; Effective: 01-01-24; Implementation: 01-02-24)
Beginning January 1, 2024, a tribal or IHS operated hospital (as defined in 42 CFR § 413.65(m))
that converts to an REH (IHS-REH) that provides hospital outpatient services to a Medicare
beneficiary may be paid for such services under the outpatient hospital All-Inclusive Rate (AIR)
that is established and published annually by the IHS, rather than the rates for REH services
described at 42 CFR § 419.92(a)(1).
A prospective IHS-REH must follow (and are subject to) the same provider enrollment
requirements and procedures outlined in 42 CFR Part 424, subpart P (including 42 CFR §
424.575) and section 10.2.1.8.1 of this chapter as all other prospective REHs (e.g., submission of
change of information rather than an initial application). Accordingly, the contractor shall
process all IHS-REH applications in the same manner it would an REH application. There is no
material difference between an IHS-REH and REH in terms of Form CMS-855A application
completion, submission, and processing. With respect to identifying the provider type in Section
2 of the Form CMS-855A, the facility shall check the “Other” box and list “Indian Health
Service – Rural Emergency Hospital.” (An alternative identification, such as “IHS-REH,” is
acceptable so long as it is clear this is the type of facility involved, though the listing must be in
Section 2(A).)
Concerning the REH letters mentioned in section 10.2.1.8.1(C), the contractor shall replace any
reference therein to “rural emergency hospital” with “Indian Health Service rural emergency
hospital” for IHS-REH applications.
As with other IHS enrollment applications, IHS-REH enrollment applications will be handled by
Novitas Solutions. (See section 10.2.1.9 of this chapter for more information.) Though IHS-
REHs may submit their applications via PECOS, the mailing address for IHS-REH paper
applications is:
