Provider Credentialing in Idaho

Idaho's healthcare market has seen rapid growth driven by migration from California, Washington, and other western states, particularly into the Boise (Treasure Valley) metro area. St. Luke's Health System and Saint Alphonsus Regional Medical Center (Trinity Health) are the dominant Boise health systems, each competing for provider alignment and payer network relationships. Idaho's overall physician supply remains below national averages, creating strong payer demand for network expansion.

Regence BlueShield of Idaho is the dominant commercial carrier. SelectHealth (Intermountain's plan, headquartered in Utah) also has Idaho market presence given Intermountain's regional expansion. PacificSource Health Plans is a Pacific Northwest-based carrier with Idaho commercial enrollment particularly in eastern Idaho. Providers in the Boise area should credential with all three.

Idaho Medicaid operates managed care through Molina Healthcare of Idaho and a limited managed care program, with significant fee-for-service components for rural populations. Idaho expanded Medicaid in 2020 following a voter initiative, adding approximately 90,000 newly eligible adults.

Arctic Health helps Idaho providers navigate Boise's rapidly growing market, Regence and PacificSource credentialing, and Idaho Medicaid's hybrid managed care structure, positioning providers to capture the state's growing insured population.
