California CDI-regulated PPO and indemnity insurers: provider dispute deadlines (2026, verified)

PPO and indemnity products regulated by the California Department of Insurance (CDI) have no 365-day dispute-filing floor — that floor exists only on the DMHC side. On the CDI side the filing window is governed by your contract with the insurer, so the same payer can lawfully hold a shorter window here than on its HMO book. Insurers must still maintain a dispute process and issue a written determination within 45 working days.

Per Appealant’s verified payer-deadline database, every value on this page is quoted verbatim from a primary source — the governing federal or California regulation — with the source linked and its effective date shown (sources re-retrieved 2026-07-04).

Calendar, business, and working days are not interchangeable, and month-based windows are never converted to day counts. Source documents were re-retrieved and verified 2026-07-04.
