SUD & Addiction Billing Built for Maryland Treatment Centers
247 Medical Billing Services provides substance abuse billing services in Maryland engineered around a state with one of the strongest public SUD benefits in the country — a HealthChoice Medicaid program whose specialty behavioral-health and addiction services run through a single statewide administrative services organization. Since 2005 our team has billed medical detox, residential rehab, partial hospitalization, intensive outpatient, and medication-assisted treatment for Maryland addiction providers, converting each ASAM level of care into a paid claim instead of a written-off day. You work with a dedicated account manager, a free 360° dashboard, HIPAA and SOC 2 Type II controls, and AAPC/AHIMA-certified coders who understand a per-diem residential day and a per-session outpatient group alike.

Why Maryland Programs Outsource SUD Billing
Maryland is, on paper, a good state to be an addiction provider — and that is exactly why the billing is unforgiving. HealthChoice, the state's Medicaid managed-care program, carves the specialty behavioral-health and SUD benefit out to a single statewide administrative services organization (the public BH-SUD ASO, historically administered by Optum and now Carelon), so most Medicaid addiction claims flow through one authorization-and-payment pipeline rather than a dozen commercial-style plans. That concentration is a gift when your workflows match the ASO's rules and a liability when they don't: one recurring authorization error, one mismatched ASAM level, or one late concurrent review can echo across an entire book of Medicaid claims at once.
first-pass-clean claims near 99% turn into deposits in weeks, with days in A/R held under 25.
authorization tracking, VOB, and correct ASO-vs-commercial routing stop rejections before a claim leaves the building.
one transparent fee replaces salaries, clearinghouse seats, and the churn of a billing hire.
So the decision to outsource in Maryland is rarely about not being able to hire. It is about depth. A program billing the HealthChoice SUD benefit through the ASO — while also carrying commercial and out-of-network residential clients out of the Baltimore and D.C.-suburb markets — needs someone who lives inside the ASO's authorization portal, the ASAM medical-necessity criteria the state adopted, and the parity rules that govern the commercial side. As a specialist billing services company, that is the exact seam we occupy. We absorb the payer complexity so your clinicians and admissions team stop losing hours to authorization callbacks and denied continued-stay days.
Why SUD Billing Services in Maryland Work Differently
The heart of Maryland SUD billing is the split between the public ASO track and everything else. A HealthChoice member's detox, residential, PHP, or IOP claim is authorized and adjudicated through the statewide BH-SUD ASO under state-adopted ASAM criteria; a commercially insured client's identical stay runs through a private plan's own utilization-review machine; and an out-of-network residential admission out of the Baltimore or Montgomery County market rides on benefit verification and single-case agreements. A medical billing services company that runs all three through one commercial template will misroute the Medicaid book on day one.
Utilization review is where Maryland residential programs lose the most. Both the ASO and commercial payers want an ASAM-justified reason for the level of care at admission and an ASAM-justified reason for every continued day after that. Concurrent review deadlines are strict, and a missed continued-stay authorization is the single most preventable denial an addiction program faces here. Our clinical-documentation and UR-support workflow exists to keep those reviews on time and defensible.
Maryland's Medicare footprint in addiction treatment is limited, but where a Part B service applies, claims route through the MAC Novitas Solutions (Jurisdiction JL). And across all payers, SUD records carry 42 CFR Part 2 federal confidentiality on top of HIPAA and Maryland's own privacy law, which changes how release-of-information, claims data, and coordination-of-benefits are handled — a constraint a generic biller rarely respects until an ASO or payer audit exposes it.
How a Maryland SUD Claim Gets Paid
Codes, revenue codes, and ASAM levels appear in this table only — never in the prose. This is how the continuum converts to payment in Maryland.
| Level of care | ASAM level | Billing basis | Where it typically routes in Maryland |
|---|---|---|---|
| Medical withdrawal management (detox) | 3.7-WM / 3.2-WM | Per-diem (rev code + H0010/H0012) | HealthChoice via BH-SUD ASO; commercial |
| Residential / inpatient rehab | 3.1 / 3.3 / 3.5 / 3.7 | Per-diem (rev code + H0018/H0019) | ASO Medicaid + OON commercial |
| Partial hospitalization (PHP) | 2.5 | Per-diem (H0035) | ASO + commercial |
| Intensive outpatient (IOP) | 2.1 | Per-session (H0015 / S9480) | ASO Medicaid + commercial |
| Outpatient (OP) counseling | 1.0 | Per-session (H0004 / group H0005) | ASO Medicaid + commercial |
| Opioid treatment program (OTP) | — | Weekly bundle (G-code / per-diem) | Medicaid OTP + commercial |
| Office-based MAT (buprenorphine) | — | E/M + drug/admin codes | Commercial + Medicaid |
| Drug testing (UDT) | — | Presumptive vs definitive (per medical necessity) | ASO + commercial, frequency-limited |

Outsourcing SUD Billing Services in Maryland
The in-house math rarely favors staying in-house. A Maryland program running a mixed HealthChoice-ASO and commercial book typically needs a biller who knows the ASO portal, a UR coordinator, a credentialing hand, and billing software — a fixed cost that does not flex with census. A professional partner replaces that fixed overhead with a variable fee tied to what you actually collect, while adding depth a single hire cannot: appeals specialists, ASO and payer-contract knowledge, and a compliance backbone.
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 Maryland medical billing services team, so one billing company owns the whole revenue cycle. The choice to outsource here is a routing-and-depth decision as much as a pricing one — and routing is exactly what an ASO-and-commercial-fluent partner gets right.

Addiction Treatment Billing Services in Maryland: FAQ
Yes. We bill Maryland's statewide behavioral-health and SUD administrative services organization to its own authorization, ASAM medical-necessity, and payment rules, and we keep those Medicaid claims routed separately from your commercial and out-of-network books.
Yes. Out-of-network is common in the Baltimore and D.C.-suburb residential market, so we run verification of benefits before admission, negotiate single-case agreements, pursue appeals, and work OON A/R until it pays rather than writing it down.
We track every authorization window and continued-stay deadline across the ASO and commercial payers, 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 Maryland.
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 an ASO or payer audit.
Usually within a few weeks. We work inside your existing EHR, run credentialing and payer-enrollment review in parallel with live billing across the ASO and commercial plans, and assign a dedicated account manager from day one so nothing stalls during the transition.
