Medical Billing Services in West Virginia.
West Virginia’s healthcare system revolves around the Mountain Health Trust Medicaid managed care program—one of the most complex in the region, with four competing MCOs including a new entrant in 2024—alongside WVU Medicine, the state’s dominant academic health system, and the newly consolidated Vandalia Health. Happy Billing brings deep expertise in WV Medicaid MCO authorization workflows, WVU Medicine and CAMC network contracting, and the opioid-epidemic-driven behavioral health billing landscape that defines care delivery across the Mountain State.
West Virginia Medicaid Billing
West Virginia Medicaid covers approximately 516,500 residents as of April 2024, down from a COVID-era peak of approximately 665,000. The state completed Medicaid unwinding through 2023-2024, with significant enrollment reductions. West Virginia expanded Medicaid under the ACA with approximately 171,000 expansion enrollees as of December 2024.
Mountain Health Trust (MHT) — Statewide Managed Care
The Mountain Health Trust is West Virginia’s comprehensive Medicaid managed care program, covering the majority of WV Medicaid beneficiaries with approximately 439,000 enrollees in managed care. As of August 1, 2024, MHT expanded from three to four MCOs with the addition of Highmark Health Options West Virginia. The four current MCOs are:
- Aetna Better Health of West Virginia — long-established MCO in the WV market
- The Health Plan of West Virginia — regional MCO serving the northern WV and Wheeling area
- UniCare (WellPoint/Elevance Health) — statewide presence, formerly Coventry WV
- Highmark Health Options West Virginia — new MCO entrant effective August 1, 2024; Highmark is the dominant Blue Cross Blue Shield affiliate in Pennsylvania and regional powerhouse
Each MCO has its own provider network, prior authorization requirements, and fee schedules. Providers serving MHT members must credential separately with each MCO where their patients are enrolled. Claims route to the specific MCO—not to a central WV Medicaid payer.
Mountain Health Promise (MHP) — Foster Care Managed Care
West Virginia operates a separate specialized managed care program for children in foster care, kinship care, and adoptive placements called Mountain Health Promise. MHP serves approximately 23,574 children and operates under a single MCO—Aetna Better Health of West Virginia—rather than the multi-MCO structure of MHT. Providers caring for this population should ensure they are credentialed with Aetna Better Health specifically.
Fee-for-Service and Carved-Out Services
Several services are carved out of MHT managed care and billed directly to WV Medicaid fee-for-service:
- Point-of-sale pharmacy benefits (all MCO members receive pharmacy through FFS Medicaid)
- Long-term care and nursing facility services
- Home and Community-Based Services (HCBS) waiver services
- Non-Emergency Medical Transportation (NEMT)
Key Billing Facts for West Virginia Providers
- Verify MCO enrollment at every visit — patients can change plans during open enrollment
- Each of the four MCOs has independent PA requirements — obtain authorization from the correct MCO
- Pharmacy claims always route to WV Medicaid FFS regardless of which MCO the patient is enrolled in
- Mountain Health Promise (foster care) members are exclusively with Aetna Better Health WV
- Providers must maintain separate credentialing with each MCO they intend to participate with
- West Virginia’s high rates of opioid use disorder drive significant behavioral health billing volume — know each MCO’s SUD and MAT prior authorization policies

West Virginia Medical Billing FAQs
How does Mountain Health Trust managed care affect my billing?
Under Mountain Health Trust, most WV Medicaid patients are enrolled in one of four MCOs (Aetna Better Health, The Health Plan of WV, UniCare, or Highmark Health Options WV as of 2024). Claims route to whichever MCO the patient is enrolled in—not to WV Medicaid directly. Each MCO has its own prior authorization rules, fee schedules, and credentialing requirements, so providers must manage four separate MCO relationships.
