Substance Use Disorder billing · Vermont
247 Medical Billing Services delivers substance abuse billing services in Vermont built for the state that invented the "Hub and Spoke" model of addiction care, where MAT flows between regional hubs and office-based spokes and every claim has to match the right node. Since 2005 our certified team has billed medical detox, residential rehab, partial hospitalization, intensive outpatient, and medication-assisted treatment for Vermont programs anchored in Burlington and reaching across the rural counties, converting every ASAM level of care into a paid claim instead of a written-off day. You get a dedicated account manager, a free 360° dashboard, HIPAA and SOC 2 Type II controls, and coders who separate a per-diem residential day from a per-session outpatient group without hesitation.
Vermont is a national reference point for addiction care because of its Hub and Spoke system, built to make medication-assisted treatment reachable in a rural state. Regional hubs — specialty opioid-treatment settings — handle complex induction and higher-acuity MAT, while office-based spokes carry maintenance and ongoing management closer to where people live. The model is coordinated under Vermont's Medicaid program, Green Mountain Care, with the Department of Vermont Health Access on the payer side and the Vermont Department of Health's Division of Alcohol and Drug Abuse Programs (VDH-ADAP) shaping SUD policy, licensing, and the Blueprint-linked care standards.
For billing, Hub and Spoke means the payment node matters as much as the service. A MAT claim from a hub does not bill like the same medication managed at a spoke, and the coordination between them creates handoffs where authorizations, coverage, and documentation can slip. A billing company that does not understand which node a claim belongs to — hub OTP bundle versus office-based spoke management — will misroute payment and trigger avoidable denials. Vermont's opioid-response infrastructure is one of the most developed in the country; billing it correctly demands a partner who already knows how the pieces connect. Layered over all of it, SUD records carry 42 CFR Part 2 federal confidentiality on top of HIPAA, changing how release-of-information, claims data, and coordination-of-benefits must be handled.
Codes, revenue codes, and ASAM levels stay here — inside the table — never scattered through the prose. This is how the addiction continuum converts to payment across Vermont.
| Level of care | ASAM level | Typical billing basis | Where it routes in Vermont |
|---|---|---|---|
| Medical withdrawal management (detox) | 3.7-WM / 3.2-WM | Per-diem (rev code + H0010/H0012) | Green Mountain Care Medicaid; commercial |
| Residential / inpatient rehab | 3.1 / 3.3 / 3.5 / 3.7 | Per-diem (rev code + H0018/H0019) | Medicaid + commercial (often OON) |
| Partial hospitalization (PHP) | 2.5 | Per-diem (H0035) | Commercial; Medicaid where covered |
| Intensive outpatient (IOP) | 2.1 | Per-session (H0015 / S9480) | Green Mountain Care + commercial |
| Outpatient (OP) counseling | 1.0 | Per-session (H0004 / group H0005) | Medicaid + commercial |
| Opioid treatment program (OTP) — hub | — | Weekly bundle (G-code / per-diem) | Medicaid Hub; commercial |
| Office-based MAT (buprenorphine) — spoke | — | E/M + drug/admin codes | Medicaid Spoke + commercial |
| Drug testing (UDT) | — | Presumptive vs definitive (per medical necessity) | Commercial + Medicaid, frequency-limited |
Most lost dollars in a Vermont SUD program trace to a short list of repeatable failures. Each has a fix, and each fix is a workflow, not a slogan.

Beyond Hub and Spoke, Vermont's addiction economy runs heavily through Green Mountain Care, giving Medicaid an unusually large role in the payer mix compared with other states. That makes clean Medicaid billing — correct level of care, correct node, defensible documentation — central to a program's survival rather than a secondary line. The commercial side still matters: residential and detox care is often out-of-network for a client's commercial plan, so verification of benefits, single-case agreements, usual-and-customary appeals, and disciplined OON follow-up remain core cash-flow work. A rural program can run at capacity and still starve if its out-of-network claims sit in a payer's medical-review queue for months.
Utilization review binds it together. Every commercial and Medicaid payer wants an ASAM-justified reason for the admission level of care and an ASAM-justified reason for each continued day, and a missed or late review is the single most preventable denial an addiction program faces. On the Medicare side, SUD is largely a Medicaid and commercial line in Vermont, but where a Part B claim arises, providers fall under National Government Services as the Jurisdiction K MAC — one more lane a competent biller keeps straight. Our clinical-documentation and UR-support workflow keeps those reviews on time and defensible.
Revenue review
A certified SUD billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in Vermont — and puts a number on what your current process is leaving on the table.
A SUD specialist will reach out within one business day.
A SUD specialist will reach out within one business day.
From a single Burlington office-based spoke to a regional hub with residential capacity, we bill the whole Vermont addiction continuum:
We serve programs across Burlington, South Burlington, Essex, Rutland, Barre-Montpelier, and Brattleboro — each billed to Green Mountain Care and to the commercial payers behind its private-pay census, statewide.
The reason to outsource here is not simply that hiring experienced SUD billers in a small rural state is hard, though it is. It is that Vermont SUD billing carries a distinctive, moving learning curve — Hub and Spoke node routing, a Medicaid-heavy payer mix, out-of-network commercial reimbursement, ASAM utilization review, and UDT compliance — and every misrouted claim or missed review is margin an addiction program cannot spare. As a specialist billing services company we absorb that complexity so your clinicians and admissions team stop losing hours to authorization callbacks and payer holds.
clean first submissions plus relentless denial follow-up recover dollars an in-house desk quietly writes off.
first-pass clean-claim rates near 99% turn into deposits in weeks, with days in A/R held under 25.
VOB, SCA, node routing, and UR tracking stop rejections before a claim leaves the building, cutting denials by up to 40%.
one transparent fee replaces salaries, clearinghouse seats, and the churn of a billing hire.
The in-house math rarely favors staying in-house. A Vermont program spanning hub and spoke settings typically needs a biller, a UR coordinator, a credentialing hand, and billing software — a fixed cost that does not flex with census and is hard to staff in a thin labor market. A professional partner replaces that overhead with a variable fee tied to what you actually collect, while adding depth an individual hire cannot: appeals specialists, payer-contract knowledge, and a compliance backbone. Roughly 90% of the denials we work are recovered, and our 98% client retention reflects programs that stayed once the math turned.
That is the case to outsource substance abuse billing to a partner built for addiction treatment rather than carry the risk alone. Programs that also run general medical lines can consolidate them with the same Vermont medical billing services team. Choosing the right medical billing services company in Vermont is as much a routing decision as a pricing one — and routing between hubs, spokes, and commercial payers is exactly what a Medicaid-and-MAT-fluent billing company gets right.
Vermont addiction programs choose us because we already speak Hub and Spoke node routing, Green Mountain Care Medicaid rules, VDH-ADAP standards, and out-of-network commercial reimbursement in the same breath. We bill the entire ASAM continuum — not just an outpatient group note — and we reconcile every unit and every per-diem day to the documentation a Vermont reviewer will actually open.
MAT claims billed to the correct hub or spoke node rather than a generic template.
clean Green Mountain Care billing where Medicaid carries an outsized share of the addiction-treatment payer mix.
withdrawal management, residential, PHP, IOP, OP, and MAT each billed to their correct per-diem or per-session logic without bundling errors.
authorization tracking and UR support so continued-stay days are approved before they are delivered, not denied after.
a named account manager, a transparent real-time dashboard, first-pass clean-claim rates near 99%, and days in A/R held under 25, with no multi-year lock-in.
Our numbers are the ones that survive scrutiny: up to 40% fewer denials once level-of-care and UR workflows are fixed, roughly 90% of worked denials recovered, and 98% client retention. We do not quote inflated figures, because a payer audit does not care about marketing.
Keep the revenue your clinical care already earns, from the northern hubs to the rural spokes.

Yes. We bill each MAT claim to its correct node — the opioid-treatment hub bundle or the office-based spoke management — under Green Mountain Care and the applicable commercial plan, and we keep those claims aligned with the coordination the model requires.
Yes. When residential or detox care is out-of-network for a client's commercial plan, we run verification of benefits before admission, negotiate single-case agreements, pursue usual-and-customary appeals, and work OON A/R until it pays rather than writing it down.
We track every authorization window and continued-stay deadline and support your clinical team so ASAM-justified reviews are filed on time. Late or missing utilization review is the most preventable SUD denial in Vermont, and it is the first thing our workflow closes.
SUD records carry stricter-than-HIPAA federal confidentiality, so we manage release-of-information, claims data, and coordination-of-benefits under Part 2 consent rules — protecting the program in a payer audit.
Whether you are a solo practice or a multi-site group, we bill Substance Use Disorder across Vermont under one dedicated account manager and a live dashboard — and treat every counted unit, authorization and appeal as recoverable revenue until it is safely paid.
