UnitedHealthcare in California: two statutory clocks, and CAQH is about to become law
California already holds plans to a 60-day credentialing decision for mental health and SUD providers, and from January 2027 a second statute adds a 90-day clock for everyone else, with provisional approval as the penalty and the CAQH application written into law. UnitedHealthcare splits its front doors in a way that decides which clock you are actually on, and filing at the wrong one wastes months before either clock starts.
Common mistake
Behavioral health does not apply to UnitedHealthcare. It applies to Optum.
Two front doors, strictly divided: Onboard Pro handles UnitedHealthcare's medical and NP onboarding, and everything behavioral, therapy, psychology, psychiatry, belongs to Optum's Provider Express. Cross the streams and the file simply waits where no reviewer will ever find it. The California-specific cost is that §1374.197's 60-day clock cannot begin, since it counts from a complete application in the correct intake, and a misfiled one never becomes complete anywhere.

California's two credentialing clocks, side by side
Two different statutes, two different windows, and a mixed practice runs on both at once. The MH/SUD clock is live today; the general clock arrives January 1, 2027 and brings a real penalty: miss it and the provider is provisionally approved for 120 days.
| HSC §1374.197 — MH & SUD (in force) | HSC §1374.198 — everyone else (from 2027) | |
|---|---|---|
| Decision deadline | 60 days from a complete application | 90 days including third-party verifications |
| Receipt acknowledgment | 7 business days | 10 business days |
| Penalty for missing it | None written into the section | Provisional approval for 120 days |
| CAQH status | Not addressed | The CAQH application becomes statutory |
| Who is exempt | — | Medi-Cal managed care (DHCS) |

How to apply to UnitedHealthcare from California
The medical path is genuinely self-service, which makes the two waits at the end easy to underestimate.
- 1 Medical and NP clinicians: start in Onboard Pro, UnitedHealthcare's onboarding tool. It runs request, credentialing, contracting and portal setup with real-time status and projected completion dates.
- 2 Authorize UnitedHealthcare to view your CAQH profile. CAQH is listed as "if applicable" for medical today, but from 2027 California law makes the CAQH application the statutory vehicle, so treat it as mandatory now.
- 3 Behavioral health clinicians: apply through Provider Express instead. CAQH participation is required.
- 4 Expect up to 45 calendar days or more of credentialing once the application is complete. Your contract is mailed within 5 business days of the credentialing request.
- 5 Allow up to a further 60 days for the signed contract to load. Confirm the load and effective date before you see members.
- 6 Date-stamp your complete-application acknowledgment. It is the trigger for whichever California clock covers you.

Hard rule
From 2027, a stale CAQH profile is a legal problem, not a paperwork problem
AB 1041 writes the CAQH application into the Health and Safety Code for commercial plans. Once it is the statutory application, an expired attestation or half-complete profile is not an inconvenience, it is the thing preventing the 90-day clock from ever starting. California practices should treat the 120-day CAQH re-attestation cycle as a hard compliance calendar item now, before the statute makes the lesson expensive.
Worth knowing
The statute covers credentialing. It does not cover contracting.
Both California sections put a clock on the credentialing decision only, and UnitedHealthcare's own published process shows why that distinction costs money: the contract is mailed within 5 business days of the credentialing request, and then a signed contract can take up to 60 more days to load. A California provider can be credentialed exactly on the statutory deadline and still be unable to bill for two more months. Plan the start date around the load date, not the approval letter.

For BH clinicians, the statute is faster than the payer's own norm. Use it.
Optum behavioral credentialing commonly runs 60 to 90 days in practice, while California law requires a decision on a complete MH/SUD application in 60. Those two facts only work in your favor if you can prove when the clock started, which means keeping the submission confirmation and the 7-business-day receipt acknowledgment §1374.197 requires. A practice that captures those dates can escalate a stalled file with the statute in hand. One that cannot is simply waiting politely. Note also that Optum group contracts are available only in limited circumstances and require a minimum of five credentialed providers, so most small California groups are really running several individual applications in parallel, each with its own clock.
