Partial hospitalization reimbursement rates

Partial hospitalization is a step down from residential: intensive, structured treatment during the day, with the patient returning home at night. On the continuum it occupies its own rung between residential treatment and intensive outpatient, and it is contracted as its own level with its own rate — not as a fraction of the residential per diem. Two things outside the rate decide what that rate is worth: the level-of-care definition in the contract, since what one plan calls partial hospitalization another may define by different hours or days, and the plan's utilization-management criteria, which decide whether a PHP day is authorized and for how long. The clinical continuum is walked level by level in the levels-of-care post; this page stays on how the level is paid.

As a facility claim carrying a partial-hospitalization revenue code — 0912 for less-intensive, 0913 for intensive partial hospitalization — with H0035, the HCPCS code for partial hospitalization treatment of less than 24 hours, as the service line. Some payers require the revenue code and the HCPCS code together for the claim to price; others key the program rate on one or the other, and a contract may define the day rate against the revenue code alone — so an “H0035 rate” and a “0913 rate” may be one contract line or two. The group, individual, and psychiatric work delivered inside the program day bills separately on the professional side. What H0035 represents, including the code set's own wording, is on the code page; how revenue codes and HCPCS codes relate on one claim is in the revenue-codes post.

The four things that determine every behavioral health facility rate, and then the program day. The contracting entity: a national behavioral health network, a commercial carrier's own book, and a regional plan each price PHP against their own network. The market: the same program day is paid differently from one metro to another. The vintage: when the rate was last negotiated. And the structure: a per-diem day rate, a case rate for the episode, or a percent of charges produce different economics for the same care and cannot be compared as one number. Then the program day itself: how many hours of programming a day, how many days a week, at what staffing and clinical intensity — those are contract facts, and two PHP rates built on different program-day definitions are not two prices for the same thing. The payer pages spell out those drivers book by book.

Not through the code. In contracting practice H0035 functions as the partial-hospitalization level-of-care line, and payers' billing rules decide which programs bill it — mental-health, substance-use, and eating-disorder PHP programs alike commonly go out on it, with the diagnosis carried in the claim's ICD coding, not in the code or the rate. A payer's Transparency in Coverage file publishes the facility's negotiated rate by billing code, so as a rule the public rate data does not distinguish one kind of partial hospitalization program from another. Where a contract does pay a named program differently, that shows up as additional rate lines behind the same level of care — not as a separate code. The practical consequence is that a PHP program's honest comparison set is every partial hospitalization program a payer pays in its market, whatever they treat. The eating-disorder post walks through what that means for a specialty program.

PHP against PHP, on the same code, in the same market, with the same payer — read as a percentile position inside the distribution of comparable facilities' negotiated rates, never as a blended average or a competitor's figure. Holding the level of care and the unit constant is the whole point: a program-day rate sits next to other program-day rates, not next to a residential per diem, and the comparison set is every partial hospitalization program the payer pays in the market. A public fee schedule price for a PHP code, where one exists, is a floor set by a state program, not the market. Ratebench and Peerbench do this on actual negotiated rates from payers' Transparency in Coverage files, resolved to the facility and scored for confidence.
