Blue Shield of California dental plans are run by a dental plan administrator, so most claims go to P.O. Box 30567, Salt Lake City, UT 84130-0567, not to a Blue Shield address in California. Electronic claims use payer ID 52133. Orange County and FEP plans have their own boxes, covered below.

Limits are the ones Blue Shield of California publishes, as summarized on this page; the patient's own plan documents win if they differ. Corrected claims and appeals have their own deadlines (see below).

Dental credentialing services →Blue Shield of California says its dental claims are handled by a dental plan administrator, and the administrator's 2026 guides send most claims to Salt Lake City. Older Chico boxes still turn up in search results and on old forms. Use the box for the plan type on the patient's card:

Blue Shield dental claims stuck? Free AR analysisBlue Shield's dental plan disclosure says all claims must be submitted to the dental plan administrator within one year after the month in which the service was rendered. A cleaning on March 10, 2026 can be filed until March 31, 2027. The calculator above works it out for any date.
Blue Shield does not publish its own provider claims page, corrected-claim process or provider appeal address. For those, call the administrator at 888-702-4171, and keep notes of each call.
Payer ID 52133 and P.O. Box 30567 in Salt Lake City are also used for UnitedHealthcare dental claims, because the same administrator processes both. That is expected. What matters is that the patient and plan on the claim match the Blue Shield card, so the claim lands in the right plan.
Blue Shield dental members can see network dentists from the administrator's network, and its national PPO providers may see members too. Check network status during insurance verification before you quote the patient.
