Colorado's State Behavioral Health Services Billing Manual is a living document, and HB 25-1002 changed utilization review criteria in 2026 — but for commercial plans, not Medicaid directly. Here is what each governs and how to keep claims clean amid the change.
Two things are changing the denial picture for Colorado behavioral health providers in 2026: a billing manual that keeps moving, and a new utilization-review law. But they operate on different tracks, and conflating them is a good way to make a compliance mistake. Here is what each governs. For the market context, see the Colorado CoBHRM guide.
Colorado's State Behavioral Health Services Billing Manual covers both HCPF-covered and BHA-covered services, and it is kept consistent with RAE and MCO contracts, BHA contracts, State Plan Amendments, and the state's waivers. The operative word is living: the manual is updated through the year, so an edition you saved months ago may be superseded. Billing against a stale edition is a quiet source of denials. Always cite the current posted edition — see the HCPF SBHS Billing Manual page.
HB 25-1002, effective January 1, 2026, requires health benefit plans that conduct utilization review of behavioral health and SUD treatment to use nationally recognized, not-for-profit clinical criteria — such as the current ASAM Criteria — for level-of-care and medical-necessity determinations. Here is the nuance that matters: the law governs commercial health benefit plans under Colorado insurance law (Title 10), not Medicaid billing directly. On a Medicaid page, it is best understood as parity and market context — it signals where utilization review is heading — rather than a change to your Medicaid billing rules. Read the signed act for the exact scope.
The practical defense against denials in a moving environment is the same regardless of which rule you are under: keep the documented level of care, the authorization, and the claim aligned on one record, and bill against the current manual edition. When utilization review across payers is converging on standardized ASAM-based criteria, documentation that cleanly justifies the level of care is what clears review, commercial or Medicaid.
Navix keeps the level of care, the documentation, and the claim on one record, so what you submit reflects what you documented — and CollaborateMD, our RCM partner, processes the claims across your RAE and commercial payers. That alignment is the durable answer to a billing manual and a UR landscape that keep changing. Confirm the current manual edition when you bill.
