Anthem Blue Cross and Carelon Behavioral Health are both part of Elevance Health, so facilities often assume Carelon handles every Anthem behavioral health claim. In California that is not a safe assumption.
Carelon's provider handbook (April 2026 revision) lists the Anthem plans it serves in other states and does not list California. For California commercial members, behavioral health disputes usually follow Anthem's own process. Confirm on the member's ID card, which names the behavioral health administrator when there is one.
Key points
- Check the member card: Anthem California or Carelon.
- Anthem: reprocessing, then a PDR, then meet and confer.
- Carelon claim appeals have a short 60-day window.
Anthem Blue Cross California: three steps
- 1Ask for reprocessing through Availity secure messaging or customer service. For length of stay or level of care issues, Anthem directs providers to its Utilization Management line.
- 2File a Provider Dispute Resolution (PDR) form if reprocessing is denied. Anthem acknowledges within 5 calendar days. Medical review and utilization management disputes are decided within 30 calendar days; standard PDRs within 45 business days.
- 3Request a meet and confer (facilities) if the PDR does not resolve it.
On Availity, a denied or finalized claim shows a Dispute the Claim option in Claim Status. The PDR form and current mailing address are on Anthem's California claims and disputes page (opens in a new tab).
Deadline
Anthem Blue Cross is regulated by California's Department of Managed Health Care for most of its California business. The state provider dispute rule requires plans to allow no less than 365 days from the plan's action, and to decide within 45 working days. Anthem Blue Cross Life and Health policies are regulated by the Department of Insurance instead, so check which entity is on the card.
When Carelon is the administrator
| Appeal type | Window | How |
|---|---|---|
| Claim appeal (payment) | 60 calendar days from the payment determination | Carelon's dispute request form, mailed to the address in the handbook or on your payment notice |
| Clinical appeal, Level I | Up to 180 calendar days | By phone, in writing or by fax |
| Clinical appeal, Level II | Up to 90 calendar days | By phone, in writing or by fax |
Carelon decides claim appeals within 30 days. Its handbook also says a provider may not bill the member until all of the member's appeals are exhausted. Carelon's portals are ProviderConnect and eServices, reached through Availity.
Out-of-state Blue members
California has two Blue plans. For out-of-state Blue members, the host plan that processes the claim also handles the dispute, and the home plan's medical necessity rules apply. Blue Shield's Claims Routing Tool tells you which California plan is the host.
What to include
