Medical Billing Services in Vermont.
Vermont operates one of the most innovative Medicaid and healthcare reform environments in the country—a fee-for-service Medicaid program wrapped in an all-payer accountable care organization (OneCare Vermont) that spans Medicaid, Medicare, and commercial insurance. The state failed in its attempt to implement a single-payer system (Act 48) in 2014 but has pursued aggressive payment reform. The provider landscape is dominated by UVM Health Network and Dartmouth Health. Happy Billing brings expertise in Vermont Medicaid FFS, OneCare Vermont ACO billing requirements, UVM Health Network credentialing, and the unique payment reform workflows that distinguish Vermont from other states.
Vermont Medicaid Billing
Vermont Medicaid (Green Mountain Care) covers approximately 220,000 residents, representing roughly one-third of the state’s population—the highest Medicaid coverage rate in New England. Vermont expanded Medicaid under the ACA in 2014. The program is administered by the Department of Vermont Health Access (DVHA).
Fee-for-Service Medicaid — No Traditional MCOs
Vermont operates a fee-for-service Medicaid program with no traditional managed care organizations. All Medicaid claims are submitted directly to Vermont Medicaid through its fiscal agent. This creates a single-payer Medicaid billing workflow, though providers must understand Vermont-specific billing rules, prior authorization requirements, and documentation standards.
OneCare Vermont — All-Payer ACO
OneCare Vermont is Vermont’s all-payer accountable care organization, operating under a CMS waiver that allows Vermont to include Medicare, Medicaid, and commercial insurance under a single ACO framework. OneCare Vermont is sponsored by UVM Health Network and Dartmouth Health and attributes patients from all payers to participating providers. Key implications for billing:
- Participating providers may receive shared savings or be at risk for shared losses based on total cost of care and quality metrics across all attributed patients
- OneCare Vermont does not process claims; underlying fee schedules and claim submission remain through Medicaid FFS, Medicare, and commercial payers
- Quality reporting and population health documentation requirements apply to OneCare-participating providers
- Providers should understand whether they are attributed under OneCare Vermont and what performance benchmarks apply to their patient population
Dr. Dynasaur — Vermont CHIP
Vermont’s CHIP program (Dr. Dynasaur) covers children and pregnant women above Medicaid income limits. Vermont has historically covered children at very high income levels (up to 312% FPL historically), reflecting the state’s progressive health coverage goals. Dr. Dynasaur claims are submitted through Vermont Medicaid FFS pathways.
Catamount Health / ACA Marketplace
Vermont operates its own ACA health insurance marketplace (Vermont Health Connect). Commercial plan participation and billing for marketplace plans follow standard commercial billing workflows, though Vermont’s small individual market means commercial plan diversity is limited compared to larger states.

Vermont Medical Billing FAQs
What is OneCare Vermont and how does it affect billing?
OneCare Vermont is Vermont’s all-payer ACO that operates under a CMS waiver to cover Medicare, Medicaid, and commercial patients under a single accountable care framework. OneCare does not process claims—claims still go through the underlying payers (Vermont Medicaid FFS, Medicare, commercial insurers)—but participating providers face shared savings/loss arrangements and quality reporting requirements based on total cost of care across all attributed patients.
