Medical Billing Services in Wyoming.
Wyoming is the least populous state in the nation, creating a unique healthcare market characterized by vast geography, significant out-of-state patient flow to larger regional centers, a fee-for-service Medicaid program, and two primary hospital systems serving distinct geographic markets. Wyoming has not expanded Medicaid under the ACA, limiting coverage for low-income adults. Happy Billing brings expertise in Wyoming Medicaid FFS billing, Wyoming Medical Center and Banner Health credentialing, tribal health coordination with Eastern Shoshone and Northern Arapaho communities, and the frontier billing rules essential for providers serving the Cowboy State’s dispersed population.
Wyoming Medicaid Billing
Wyoming Medicaid is administered by the Wyoming Department of Health (WDH) and covers approximately 80,000-100,000 residents—a small number reflecting both the state’s small population and the absence of ACA Medicaid expansion. Wyoming has repeatedly declined to expand Medicaid, leaving an estimated 20,000-30,000 adults in a coverage gap.
Fee-for-Service Medicaid — No MCOs
Wyoming operates a fee-for-service Medicaid program with no managed care organizations. All Medicaid claims are submitted directly to Wyoming Medicaid through the state’s fiscal agent (DXC Technology). Wyoming Medicaid covers traditional populations: children, pregnant women, low-income parents at very restrictive income levels (parents must be near the poverty line), seniors, and individuals with disabilities.
KidCare CHIP
Wyoming’s CHIP program (KidCare) covers children in families with incomes between 100%-200% FPL who are uninsured and not Medicaid-eligible. KidCare uses the Medicaid FFS billing system—providers bill the same way as for Medicaid-covered children.
Wyoming Workers' Compensation
Wyoming’s state-run Workers’ Compensation program is a significant payer given the state’s large extraction industries (oil, gas, mining, coal). Wyoming is one of the remaining states with an exclusive state-fund workers’ compensation system, meaning all WC claims route to the Wyoming Department of Workforce Services. Providers treating injured workers must be enrolled with and bill the state WC program directly.
Tribal Health — Wind River Reservation
Wyoming’s primary tribal health population is centered on the Wind River Reservation in Fremont County, home to the Eastern Shoshone and Northern Arapaho Tribes. The Wind River Indian Health Service serves this population. Wyoming Medicaid may serve as a secondary payer for IHS-covered individuals, and providers in Fremont County and surrounding areas should understand IHS billing and Purchased/Referred Care authorization workflows.
Major Payers and Health Systems in Wyoming
Wyoming Medical Center
Wyoming Medical Center (WMC) in Casper is Wyoming’s largest hospital and serves as the primary referral and Level II Trauma Center for central and western Wyoming. WMC is an independent, not-for-profit hospital and the closest thing Wyoming has to an academic medical center. Credentialing with WMC follows its independent medical staff office process.
Banner Health Wyoming
Banner Health (headquartered in Phoenix, Arizona) operates Banner Wyoming Medical Center in Casper—competing with the independent Wyoming Medical Center—as well as hospitals in Greybull, Worland, and other Wyoming communities. Banner’s system-wide credentialing processes apply for Wyoming facilities.
Cheyenne Regional Medical Center
Cheyenne Regional Medical Center (CRMC) is the primary hospital in Cheyenne, Wyoming’s capital and largest city. CRMC is a county-owned, not-for-profit hospital and serves as the main referral center for southeastern Wyoming. Cheyenne’s proximity to Denver, Colorado means many patients bypass CRMC for specialized care at Colorado health systems.
Sheridan Veterans Affairs Medical Center
Sheridan VA Medical Center is one of Wyoming’s largest healthcare facilities by volume and serves veterans across northern Wyoming and southern Montana. Providers seeing veterans at non-VA facilities should understand VA Community Care billing (formerly Choice/Mission Act billing) and ensure enrollment in the VA’s community care network.

Wyoming Medical Billing FAQs
Has Wyoming expanded Medicaid?
No. Wyoming has repeatedly declined to expand Medicaid under the ACA. Coverage for adults without dependents is extremely limited. This leaves an estimated 20,000-30,000 Wyomingites in a coverage gap and creates significant uncompensated care challenges for Wyoming providers.
