Medical billing services in Vermont
Short answer
Medical billing services in Vermont deal with a Medicaid program with no private health plans: CMS counts every Vermont Medicaid enrollee in full-benefit managed care because the Department of Vermont Health Access is the single MCO entity under the Global Commitment to Health demonstration, and every claim goes to Gainwell, its fiscal agent.
Gainwell must receive a Medicaid primary claim within 180 days of the begin date of service, insurers owe payment or notice on a claim within 30 days under 18 V.S.A. § 9418, and non-emergency rides run through public transit brokers under contract to DVHA. A Remitwright dedicated biller keeps those rules per payer, serving Vermont practices remotely. Rules for other states are on the medical billing services by state page.

Vermont Medicaid (Green Mountain Care)
Vermont Medicaid (Green Mountain Care) is run by the Department of Vermont Health Access (DVHA), Agency of Human Services. Fee-for-service claims and provider enrollment go through the Vermont Medicaid Portal (Gainwell Technologies)2, at www.vtmedicaid.com. Single public plan: CMS counts all 165,372 of Vermont's Medicaid enrollees, 100 percent, in full-benefit managed care in 2024, because the Department of Vermont Health Access itself acts as the state's single MCO entity under the Global Commitment to Health demonstration3.
Medicaid claim filing limit (every member, through Gainwell): 180 days from the begin date of service for Gainwell to receive a Medicaid primary claim, with inpatient claims counted from the discharge date1. Medicare primary claims are due within 180 days of Medicare's processing date, with the Medicare Attachment Summary Form or EOB attached on paper; claims with other insurance primary, and claims for members or providers granted retroactive eligibility or enrollment, get 365 days from the date of service; adjusted or recouped claims get 180 days from the adjustment date. A claim is filed when the fiscal agent assigns an internal control number, and failures by a software vendor, billing agent or clearinghouse are not accepted as circumstances beyond the provider's control. One clock applies to every member because there are no separate plans.
Managed care plans4
- Department of Vermont Health Access (Global Commitment to Health)The state agency as Vermont's single MCO entity, 165,372 members in CMS's 2024 plan file, 21,593 of them dually eligible, under a managed care-like model that CMS's notes describe as operating like a non-risk prepaid inpatient health plan
Each plan is credentialed separately, has its own portal and its own appeal route. A practice that joins Vermont Medicaid through one plan is not in network with the others until each contract is in place.
Commercial payers and the prompt-pay law
Commercial payers active in Vermont9: Blue Cross and Blue Shield of Vermont, MVP Health Plan, Cigna Health and Life Insurance Company. No two of them share a provider manual: filing windows, corrected-claim processes and appeal levels are set payer by payer, and the timely filing limits table lists verified deadlines, each with its source.
Clean-claim payment window under 18 V.S.A. § 9418, payment for health care services: 30 days after receiving a claim for a health plan, contracting entity or payer to pay it or to take one of the other actions the section lists, such as notifying the provider that the claim is contested or denied6. A contested claim is one the payer cannot adjudicate for lack of information or reasonable access to it; interest accrues at 12 percent a year on amounts unpaid under the conditions in subsection (e), and an electronic claim must be acknowledged within 24 hours after the start of the next business day following receipt. The practical use of the statute is in A/R follow-up: a clean claim past the statutory window is escalated with the statute cited, and interest is requested where the law provides it.
NEMT and home care in Vermont
Non-emergency medical transportation. Statewide service for traditional, Primary Care Plus and Dr. Dynasaur members, provided through personal services contracts between the Agency of Human Services, DVHA and local public transit brokers; a medical provider must confirm a member's appointment when a Vermont Medicaid transportation provider asks, and DVHA requires transportation providers to verify 5 percent of all ride requests1. The NEMT billing in Vermont page covers trip documentation, broker claims and reconciliation.
Electronic visit verification. Vermont attested to EVV compliance for personal care services under the section 1905(a)(24) state plan benefit and its section 1115 demonstration, and CMS accepted the attestation on January 13, 2021, so no FMAP reduction applied7. The letter reserves CMS's right to apply reductions if the state's system turns out not to match its attestation, and requires the state to update its compliance survey if it adds authorities that cover personal care. See home care billing in Vermont for waiver programs, EVV exceptions and authorizations.
Rules that change how Vermont claims are billed
180 days from the begin date of service, and the fiscal agent's control number is the only proof1
The General Billing and Forms Manual dated October 22, 2026 gives Gainwell 180 days from the begin date of service to receive a Medicaid primary claim, 180 days from the discharge date for inpatient stays, 180 days from Medicare's processing date when Medicare is primary, and 365 days from the date of service when other insurance is primary or when a member or provider was granted retroactive eligibility or enrollment. A claim counts as filed when the fiscal agent documents receipt by assigning an internal control number; postmarks, certified mail receipts, dated signatures and clerical claim listings are not proof, holidays and closures do not extend the period, and waiting for prior authorization or correspondence is not an acceptable reason for late filing. If a claim has not appeared on a remittance advice within 30 days of transmission or mailing, the provider is expected to check with the fiscal agent and resubmit.
The state is the plan: DVHA acts as Vermont's single MCO entity5
CMS's 2024 state tables record the Global Commitment to Health demonstration as a full-benefit MCO plus MLTSS program with one participating plan, the Department of Vermont Health Access, running statewide since October 1, 2005 under section 1115(a) authority with its waiver through December 31, 2027. Enrollment is mandatory and pre-assigned for every population including full duals and foster children, the covered benefits run from inpatient care to HCBS waiver services, private duty nursing and non-emergency transportation, HEDIS and CAHPS reporting are required, and Health Services Advisory Group is the external quality review organization. For a practice that means one Medicaid enrollment, one fee schedule and one claims route, with the Global Commitment rules sitting behind DVHA's own.
Payers have 30 days to pay or respond, with 12 percent interest behind it6
Under 18 V.S.A. § 9418, a health plan, contracting entity or payer has 30 days after receiving a claim to pay it or to take one of the other steps the section allows, such as notifying the provider that the claim is contested, meaning the payer lacks the information or reasonable access to the information needed to decide liability, or denied. Electronic claims must be acknowledged within 24 hours after the beginning of the next business day following receipt, and unpaid amounts accrue interest at 12 percent a year under the conditions subsection (e) sets. The section does not define a clean claim, so the contract's definition and the 30-day receipt date are what a Vermont commercial follow-up cites.
Rides come from public transit brokers, and 5 percent of ride requests are verified with the practice1
Non-emergency medical transportation is a statewide covered service for members in traditional Medicaid, Primary Care Plus and Dr. Dynasaur, provided through personal services contracts between the Agency of Human Services, DVHA and local public transit brokers rather than a single statewide broker. CMS requires transportation providers to verify that trips go to eligible medical appointments, DVHA currently requires them to verify 5 percent of all ride requests, and every medical provider is required to confirm a member's appointment when a Vermont Medicaid transportation provider asks. Ambulance claims follow a different rule: the physician certifies that other means of transportation would endanger the member's health, and a service the member could have reached by taxi or bus falls under NEMT, not ambulance.
Medicare crossovers arrive on their own, and a Medicare denial gets twelve months1
When Vermont Medicaid eligibility is marked on the Medicare claim, the claim and any later adjustments cross over to Gainwell automatically, and a provider that has not seen the DVHA payment within 30 days of the Medicare paid date submits the claim with the Medicare Attachment Summary Form from the Vermont Medicaid forms page. A service Medicare denies as non-reimbursable but DVHA covers is billed on a CMS-1500 completed to DVHA specifications with the Medicare denial attached, within twelve months of the date of service. Out-of-state providers other than New Hampshire's bill their regional Medicare carrier first and then send Gainwell the coinsurance or deductible claim with the summary form showing the Medicare payment date, and paper crossovers for dates of service more than two years old need both the form and the Medicare EOB.
Home health EVV was accepted by CMS from the start of 20248
CMS's December 19, 2023 letter to Vermont's Medicaid Director accepted the state's attestation that its EVV system met section 1903(l) of the Social Security Act for home health care services under the section 1905(a)(7) home health benefit and the section 1115 demonstration, so no FMAP reduction applied to those services. Like the 2021 personal care letter, it reserves CMS's right to apply reductions if the system does not match the attestation and requires the state to update its survey if it adds authorities, which is the standard a home health agency's EVV records are held to.
