Denial trigger
APG / outpatient coding error
Why it happens in New York
Outpatient SUD billed without correct ambulatory-patient-group logic
How we prevent it
We apply New York APG rules and reconcile each visit line
Substance Use Disorder billing · New York
247 Medical Billing Services delivers substance abuse billing services in New York built for the state's OASAS-licensed system and its Medicaid Managed Care addiction benefit — the ambulatory-patient-group world where a single misplaced modifier or an unauthorized level of care quietly erases a day of care. Since 2005 our team has billed detox, residential rehab, PHP, IOP, outpatient, and medication-assisted treatment for New York addiction programs, turning every ASAM level and every OASAS-certified service into a clean, paid claim rather than a denial to appeal later. You get a dedicated account manager, a free 360° dashboard, HIPAA and SOC 2 Type II controls, and certified coders who understand the difference between an APG outpatient visit and a residential per-diem.
Start with the denials, because in New York the denial pattern tells you where the money leaks. Most lost dollars trace to a short list of repeatable failures — each preventable with a workflow rather than a heroic month-end scramble.

Fixing this pattern is not glamorous, but it is where up to 40% fewer denials and roughly 90% of worked denials recovered actually come from. We would rather prevent a rejection than celebrate appealing one.
New York addiction programs choose us because we already speak OASAS, Medicaid Managed Care, and APG outpatient in the same breath. We bill the entire ASAM continuum and reconcile every unit, visit, and per-diem day to the documentation a managed-care utilization reviewer will actually open.
we bill Part 800-certified programs to the service definitions and reporting expectations the Office of Addiction Services and Supports enforces.
the SUD benefit runs through mainstream managed-care plans and HARPs, each with its own authorization and claim rules that we bill to natively.
ambulatory-patient-group logic applied correctly so outpatient and MAT visits pay the first time.
authorization tracking and UR support so continued-stay days are approved before they are delivered.
a named account manager, a transparent dashboard, first-pass clean-claim rates near 99%, A/R held under 25 days, 98% client retention, and no multi-year lock-in.
Codes, revenue codes, and ASAM levels live here in the table — never scattered through the prose. This is how the OASAS continuum converts to payment in New York.
| Level of care | ASAM level | Typical billing basis | Where it routes in New York |
|---|---|---|---|
| Medical withdrawal management (detox) | 3.7-WM / 3.2-WM | Per-diem (rev code + H0010/H0012) | Medicaid MC + commercial |
| Residential / inpatient rehab | 3.1 / 3.3 / 3.5 / 3.7 | Per-diem (rev code + H0018/H0019) | Medicaid MC + OON commercial |
| Partial hospitalization (PHP) | 2.5 | Per-diem (H0035) | Commercial; managed care |
| Intensive outpatient (IOP) | 2.1 | Per-session / APG (H0015 / S9480) | Medicaid MC (APG) + commercial |
| Outpatient (OP) counseling | 1.0 | APG visit (H0004 / group H0005) | Medicaid MC (APG) + commercial |
| Opioid treatment program (OTP) | — | Weekly bundle (G-code / per-diem) | Medicaid MC + commercial |
| Office-based MAT (buprenorphine) | — | E/M + drug/admin codes | Medicaid MC + commercial |
| Drug testing (UDT) | — | Presumptive vs definitive (per medical necessity) | Medicaid MC + commercial, frequency-limited |
Because most New York SUD care runs through commercial and Medicaid rather than Medicare, the Part B MAC (National Government Services) matters mainly for crossover and dual-eligible edge cases — but when it does, we bill it correctly rather than letting a dual claim stall.
New York's addiction system is defined by OASAS. Programs are certified under Part 800, services carry state-defined definitions, and the dominant payer is Medicaid delivered through managed-care plans — mainstream plans plus Health and Recovery Plans (HARPs) for members with significant behavioral needs. Outpatient SUD is largely billed through the ambulatory patient group (APG) methodology, a visit-based system with its own bundling and weighting rules that behaves nothing like a straight fee-for-service claim. A billing company that has never touched APG will underbill or misbill outpatient visits without ever realizing it.
The state has also poured resources into its opioid-crisis response — expanded MAT access, OTP capacity, and low-threshold buprenorphine — which multiplies the MAT and OTP billing mechanics a program must handle. New York's Medicaid buy-in for OTP and its investment in mobile and telehealth-delivered addiction care mean a single program may bill in-person residential, APG outpatient, an OTP bundle, and a telehealth MAT visit in the same week, each with distinct rules. And New York still carries a meaningful commercial and out-of-network residential segment, so verification of benefits, single-case agreements, and OON appeals sit alongside the Medicaid work. Layer 42 CFR Part 2 confidentiality on top, and the operational reality is a program juggling OASAS reporting, managed-care authorizations, APG coding, and Part 2 consent all at once. That is a specialist's job, not a side duty for a front-desk hire.
There is also a staffing dimension unique to markets like New York City. Qualified SUD billers who understand both APG and managed-care utilization review are scarce and expensive here, and turnover in a single-biller shop means claims stall the moment that person is out. Concurrent review in particular is unforgiving: a HARP or mainstream plan expects an ASAM-justified continued-stay review on a fixed cadence, and a review filed a day late can cost the program the entire disputed stay. Our team carries redundancy — multiple coders, appeals specialists, and UR support — so a vacation or a sick week never becomes a cash-flow event, and no continued-stay day quietly falls through because one person was overloaded.
Revenue review
A certified SUD billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in New York — and puts a number on what your current process is leaving on the table.
A SUD specialist will reach out within one business day.

The reason to outsource is not simply staffing relief. It is that New York SUD billing carries a steep, moving learning curve — OASAS rules, managed-care authorizations, APG outpatient logic, 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 clinical and admissions staff stop losing hours to plan callbacks and authorization holds.
clean first submissions plus relentless denial follow-up recover dollars an in-house desk quietly writes off.
first-pass-clean claims near 99% turn into deposits in weeks, with A/R held under 25 days.
APG coding, plan routing, VOB/SCA, and UR tracking stop rejections before a claim leaves the building.
one transparent fee replaces salaries, clearinghouse seats, and the churn of a billing hire.
The in-house math rarely favors staying in-house. A New York program running Medicaid managed care plus a commercial book needs a biller who knows APG, a UR coordinator, a credentialing hand, and billing software — a fixed cost that does not flex with census. A professional partner replaces that overhead with a variable fee tied to what you actually collect, and adds appeals specialists and payer-contract depth an individual hire cannot match.
That is the case to outsource substance abuse billing to a partner built for addiction treatment. Programs that also run general medical lines can consolidate them with the same New York medical billing services team. Choosing the right medical billing services company in New York is as much a routing decision as a pricing one — and OASAS-and-managed-care routing is exactly what an experienced billing company gets right.
From a single OASAS-certified outpatient clinic to a multi-borough residential network, we bill the whole New York addiction continuum:
We serve programs across New York City and the five boroughs, Long Island, Westchester and the Hudson Valley, the Capital Region, Buffalo, Rochester, and Syracuse — each billed to its managed-care plans and OASAS rules, statewide.

Our certified coders reconcile every per-diem and visit line against the documentation a utilization reviewer actually opens, and we keep addiction records under 42 CFR Part 2 consent rather than HIPAA alone. The result across New York programs: clean-claim rates near 99%, A/R held under 25 days, and up to 40% fewer denials since 2005. Request a revenue review.
