Detox is the most acute level of care a behavioral health facility contracts for, and in reimbursement terms it is a per-diem line: the facility is paid for each day of medically monitored withdrawal management, not for the visits delivered inside it. A facility's “detox rate” is therefore one entry in a schedule of level-specific rates, negotiated on its own terms with each payer. This page covers how a detox day bills, what determines the rate a payer pays for it, how the public Medicaid schedule relates to it, and how a facility finds out where its own rate stands.

What is detox as a level of care in contracting terms?
Detox — medically managed detoxification and withdrawal management — sits at the most acute end of the behavioral health continuum, ahead of residential treatment. Clinically there is a meaningful distinction between medically managed detox, with closer supervision and higher acuity, and sub-acute withdrawal management; contracts often treat the two differently, and a contract's level-of-care definition decides which a facility is paid for. The rate is only as good as the authorization behind it: a plan's utilization-management criteria determine whether a detox day is recognized and paid at all. The clinical continuum itself is walked level by level in the levels-of-care post; this page stays on how the level is paid.

How does a facility bill for a day of detox?
As a facility claim carrying the detoxification room-and-board revenue code, 0126, with the HCPCS code for sub-acute detox in a residential addiction program, H0010, as the service line. Some payers require the revenue code and the HCPCS code together for the claim to price; others key the rate on one or the other, so “the H0010 rate” and “the 0126 rate” may be one contract line described two ways or two different lines. Detox delivered in an acute hospital setting bills on hospital revenue codes and hospital rate structures instead, and the physician and nursing work during a detox stay bills separately on the professional side. What H0010 represents, and how revenue codes and HCPCS codes relate on one claim, are on the code page and the revenue-codes post.

What determines a detox reimbursement rate?
Four things, before the facility's own case is made. The contracting entity: whether the contract is held by a national behavioral health network, a commercial carrier's own book, or a regional plan, since each prices detox against its own network. The market: the same level of care is paid differently from one metro to another. The vintage: a detox per diem negotiated years ago and never revisited sits where the market was then. And the structure: a straight per diem, a case rate that covers the withdrawal episode, or a percent of charges produce different economics for the same care and cannot be compared as if they were one number. On top of those sit the program facts a facility negotiates on — medical staffing, monitoring intensity, length of stay — and the level-of-care definition the contract attaches to the code. The payer pages spell out those drivers book by book.

How does the Medicaid fee schedule relate to a detox rate?
It is a floor reference, not a benchmark. Because state Medicaid fee schedules are public and detox is one of the services they price, a search for a detox rate often surfaces a state schedule figure first — a price set by regulation, the same for every enrolled provider, with nothing to negotiate. A commercial detox per diem is a contract outcome that varies facility to facility, and a Medicaid managed-care plan's rate is a third thing again: its own arrangement, not the state schedule. Read a public Medicaid detox rate as the lowest rate a public program has set for the service in that state, not as what commercial payers pay facilities like yours. TierBench carries the Massachusetts and North Carolina state Medicaid fee schedules as that reference floor beneath the commercial distribution for the same code.

How does a facility benchmark its detox rate?
Detox against detox — never against a blended facility number. The benchmark places a facility's negotiated detox rate inside the distribution of comparable facilities' negotiated rates on the same code, in the same market, with the same payer, and reads the result as a percentile position rather than as a competitor's figure. Holding the level of care constant is the whole point: a detox per diem compared against a residential per diem is a comparison of two different services. Ratebench and Peerbench do this on actual negotiated rates from payers' Transparency in Coverage files, resolved to the facility and scored for confidence, with the Massachusetts and North Carolina Medicaid schedules beneath the distribution as a reference floor. The fastest way to see where your detox rate stands is a free rate analysis of your own contract.
