Behavioral health billing codes
Behavioral health facilities are paid on a small set of HCPCS codes and revenue codes — a per diem for detox, a per diem for residential, a program rate for PHP or IOP. The same code can carry very different negotiated rates from one facility to the next, and payers differ on whether they key a rate to the HCPCS code, the revenue code, or the two together. These pages explain what each code represents, what bills under it, which revenue codes it appears with, and why a rate on it is only comparable to another rate on it when the rest of the contract matches. Below the facility codes are the revenue codes they pair with and the CPT® codes clinicians bill, each with its official description.
Facility codes (HCPCS)
The HCPCS per diems and program rates most behavioral health facility contracts are built around.
Sub-acute detoxification
The residential detox per-diem code. Pairs with revenue code 0126; the code behind most “detox reimbursement rate” questions.
Read the guideShort-term residential
The behavioral health residential per-diem code, without room and board. Pairs with revenue codes 1002 and 1001; carries every residential program, whatever the diagnosis.
Read the guideHospital residential treatment
The hospital-based residential per-diem code — H0018's sibling for residential programs run inside a hospital. Same accommodation revenue codes, different setting.
Read the guidePartial hospitalization
The mental health partial-hospitalization code — a program day of less than 24 hours. Pairs with revenue codes 0912/0913; in practice carries every PHP program, whatever the diagnosis.
Read the guideIntensive outpatient
The intensive outpatient program code — at least three hours a day, three days a week, in the code set's own terms. Pairs with revenue codes 0905/0906; in practice carries every IOP program, whatever the diagnosis.

How to read this section
Two things hold across every page here. First, a code is not a rate: a public fee schedule may list one price for H0010, but a commercial negotiated rate on H0010 is a contract outcome that varies facility to facility (Medicaid fee schedules vs. commercial negotiated rates). Second, codes are diagnosis-agnostic: H0018 is the residential per diem for a substance-use program and an eating-disorder program alike (there is no eating-disorder billing code).
A facility line and a professional line are different contracts. The HCPCS and revenue codes above are what the facility is paid for a day or a program; the CPT® codes are what a clinician is paid for a session, a test or an evaluation — often under a different contract, and sometimes with a different payer entity. A benchmark only means something when it compares like with like.
The facility-level HCPCS codes above carry most behavioral health facility contracts. How revenue codes and HCPCS codes relate on one claim — and why “the 1002 rate” and “the H0018 rate” may be one line or two — is explained in Behavioral health revenue codes, explained.
How these codes become comparable rates — extraction, normalization, and level-of-care mapping — is on the coverage and methodology page.
