Nurse advice line coverage in the Navajo Area.
The Navajo Area covers Arizona, New Mexico, and Utah. TULQ provides 24/7 telephone nurse triage for the IHS service units, 638 tribal health programs, and Urban Indian Organizations that serve it.
The Navajo Area serves the Navajo Nation, the largest reservation in the United States at roughly the size of West Virginia. Households without reliable telephone or broadband service, long distances between communities, and a service population concentrated across three states make after-hours access a persistent structural problem rather than an occasional one.
Facilities and programs in this Area
The Navajo Area includes IHS-operated service units alongside tribally operated 638 programs and compacts. Illustrative facilities:
- Gallup Indian Medical Center
- Chinle Comprehensive Health Care Facility
- Northern Navajo Medical Center, Shiprock
- Tuba City, Crownpoint, and Kayenta service units
This is not a complete list. The Indian Health Service maintains the authoritative directory of Area facilities and service units, and tribally operated programs change hands between IHS and tribal operation over time.
Recent procurement activity
The Gallup Service Unit published a Sources Sought notice for nurse advice line services in January 2025, with a five-year period of performance and a Buy Indian Act preference under NAICS 621399.
Gallup Indian Medical Center is one of the highest-volume facilities in the IHS system, which makes the after-hours telephone load correspondingly large.
These notices are matters of public record and are summarized here as context. A Sources Sought notice is market research, not a commitment to solicit or award, and notices are routinely amended or superseded. Work from the current posting. More for contracting officers.
What coverage looks like here
The service is the same everywhere: one number, answered any hour by a U.S. state-licensed registered nurse working Schmitt-Thompson telephone triage protocols, with the encounter documented and returned to the facility. What changes by Area is the context around it, how far the nearest emergency department is, what the winter looks like, whether the caller has reliable cellular service, and how the program is funded.
For IHS-operated service units, after-hours coverage is typically procured through the Area office and appears publicly on SAM.gov. For 638 programs and compacts, it is procured directly by the tribe or tribal organization, with no IHS solicitation required. Both paths are covered on our tribal health page.
