Navigating the state-specific Medicaid portal requirements for credentialing services in Vermont is critical to avoiding claim denials.

Back to All Resources

Vermont operates its Medicaid program (Green Mountain Care) entirely on a fee-for-service basis with no mandatory managed care organizations, and the state’s groundbreaking All-Payer Model creates a unique value-based care environment unlike any other state.

What Is the Vermont Medicaid Portal?

The Vermont Medicaid Provider Portal is the centralized enrollment gateway operated by the Department of Vermont Health Access (DVHA) in partnership with Gainwell Technologies.

This centralized platform manages all provider licensing validations, federal exclusions checks, revalidations, and claims billing. All healthcare practitioners must obtain active status in the portal to participate in Vermont's healthcare network.

Green Mountain Care: Vermont's Public Managed Care Model

Unlike states that contract with multiple private insurance plans, Vermont does not use commercial Managed Care Organizations (MCOs) for its Medicaid program.

Instead, the state operates a public managed care model under a Section 1115 waiver, known as the Green Mountain Care program. General Medicaid is administered as an Administrative Services Only (ASO) model by the state, serving as the single payer. This greatly simplifies billing and credentialing since providers only need to manage a single central contract with the Department of Vermont Health Access (DVHA).

✔ B2B Strategy: Vermont's single-payer public model eliminates the need for parallel MCO contracting. Focus 100% of your administrative effort on securing active status in the central DVHA portal to begin billing.

The All-Payer Model: Vermont’s Innovation

Vermont’s All-Payer Model aligns Medicaid, Medicare, and commercial payers under a single ACO framework through OneCare Vermont.

  • OneCare Vermont is an ACO that coordinates care across all payer types
  • Providers can participate in OneCare voluntarily — not required for Medicaid enrollment
  • All-Payer Model creates population-based payment opportunities
  • Participation may affect payment methodology but not enrollment eligibility

✔ Unique Opportunity: Vermont’s All-Payer Model allows providers to align Medicaid, Medicare, and commercial under one ACO. Consider OneCare Vermont participation for value-based revenue.
