Substance Use Disorder billing · Santa Rosa, CA
247 Medical Billing Services provides substance abuse billing services in Santa Rosa built for Sonoma County wine-country addiction care — a Partnership HealthPlan of California Medi-Cal population governed by the county's own Drug Medi-Cal system, alongside a commercial and out-of-network residential book. Since 2005 our team has billed medical detox, residential rehab, partial hospitalization, intensive outpatient, and medication-assisted treatment for addiction programs across Santa Rosa and the North Bay, turning each ASAM level of care into a paid claim instead of an uncollected day. You get a dedicated account manager, a free 360° dashboard, HIPAA and SOC 2 Type II controls, and AAPC/AHIMA-certified coders fluent in per-diem residential and per-session outpatient billing alike.
Santa Rosa is the largest city in Sonoma County and the North Bay's addiction-treatment hub, and its treatment market carries features you will not find in a big-metro build. Demand here has climbed with the same opioid and stimulant pressures affecting the rest of California, but capacity is constrained — a handful of detox beds, a growing set of outpatient and residential programs, and a workforce stretched by the region's high cost of living. For a program in this market, every payable day matters more.
Sonoma County's Medi-Cal population is served by Partnership HealthPlan of California (PHC), the regional Medi-Cal managed-care plan across much of Northern California, and the county governs its own Drug Medi-Cal delivery through Sonoma County Behavioral Health. That means the rate sheets, authorization windows, and documentation forms your Drug Medi-Cal claims answer to are set locally, not at a statewide desk. Alongside the public system, wine-country and North Bay residential programs draw privately insured clients, so a commercial and out-of-network book runs in parallel. Billing a Santa Rosa program well means fluency in both lanes at once.
Codes, revenue codes, and ASAM levels appear only in the table below — never scattered through the prose. This is how the addiction continuum converts to payment for Santa Rosa programs.
| Level of care | ASAM level | Typical billing basis | Where it routes in Santa Rosa |
|---|---|---|---|
| Medical withdrawal management (detox) | 3.7-WM / 3.2-WM | Per-diem (rev code + H0010/H0012) | OON commercial; Sonoma Drug Medi-Cal |
| Residential / inpatient rehab | 3.1 / 3.3 / 3.5 | Per-diem (rev code + H0018/H0019) | OON commercial + DMC-ODS residential |
| Partial hospitalization (PHP) | 2.5 | Per-diem (H0035) | Commercial; DMC-ODS where covered |
| Intensive outpatient (IOP) | 2.1 | Per-session (H0015 / S9480) | Commercial + Drug Medi-Cal (PHC) |
| Outpatient (OP) counseling | 1.0 | Per-session (H0004 / group H0005) | Drug Medi-Cal + commercial |
| Opioid treatment program (OTP) | — | Weekly bundle (G-code / per-diem) | DMC-ODS OTP + commercial |
| Office-based MAT (buprenorphine) | — | E/M + drug/admin codes | Commercial + Medi-Cal; Noridian JE for dual-eligible |
| Drug testing (UDT) | — | Presumptive vs definitive, per medical necessity | Commercial + Medi-Cal, frequency-limited |
Most lost dollars in a North Bay program trace to a short list of repeatable failures. Each has a workflow fix, not a slogan.

Revenue review
A certified SUD billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in Santa Rosa, CA — and puts a number on what your current process is leaving on the table.

Two things make Santa Rosa billing its own discipline. The first is utilization review. Every commercial and Drug Medi-Cal payer wants an ASAM-justified reason for the level of care at admission and another for every continued day, and concurrent review is unforgiving — a late or missing review is the single most preventable denial an addiction program faces, and in a capacity-constrained market it is the most costly. The second is routing. With Partnership HealthPlan on the Medi-Cal side and a parallel commercial and out-of-network book, an admission billed to the wrong door stalls before it is adjudicated.
Out-of-network mechanics matter for the private-pay side: verification of benefits, single-case agreements, usual-and-customary appeals, and out-of-network A/R decide whether a residential stay is reimbursable at all. And across everything, SUD records carry 42 CFR Part 2 federal confidentiality on top of HIPAA, which changes how release-of-information and coordination-of-benefits must be handled — a nuance a generalist billing company rarely respects until a payer audit exposes it. A slice of outpatient and office-based MAT volume also coordinates through the Noridian JE Medicare desk for dual-eligible clients.
From a single Santa Rosa outpatient program to a multi-site North Bay residential network, we bill the whole addiction continuum:
We work with programs across Santa Rosa and nearby Rohnert Park, Windsor, Petaluma, and Sebastopol, each billed to Sonoma County's Drug Medi-Cal rules and to the commercial payers behind the region's private-pay census.
The reason to outsource here is not that hiring billers is hard. It is that North Bay SUD billing carries a steep, constantly shifting learning curve — Sonoma County Drug Medi-Cal rules, Partnership HealthPlan routing, out-of-network reimbursement, ASAM utilization review, UDT compliance — and every misrouted claim or missed review is margin a capacity-constrained 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.
eligibility and benefit verification, single-case agreements, correct routing, and denial management stop rejections before a claim leaves the building.
one transparent fee replaces salaries, clearinghouse seats, and the churn of a billing hire.
A Santa Rosa program running a mixed Drug Medi-Cal and out-of-network book typically needs a biller, a UR coordinator, a credentialing hand, and billing software — fixed overhead that does not flex with census and is hard to staff in a high-cost, tight labor market. A professional partner replaces that with a variable fee tied to what you actually collect, and up to 40% fewer denials plus 90% of worked denials recovered are what make the math work. That is the case for Outsourcing SUD Billing Services in Santa Rosa to a team built for addiction treatment, and the case that pushes many programs toward Substance Abuse Billing Services Outsourcing rather than carrying the risk alone. Programs that also run general medical lines can consolidate them with the same California medical billing services team, because choosing the right medical billing services company in Santa Rosa is as much a routing decision as a pricing one — and a county-and-commercial-fluent billing company gets routing right.
