Delta Dental's rule is that a claim goes to the Delta company that provides the patient's coverage, not to the Delta company where your office is. A patient who works for a company headquartered elsewhere can carry a Delta Dental of California card while living in another state, and the reverse is just as common. Read the company name on the ID card, or look the patient up under My Patients in the National Dentist Dashboard, before you submit.
Your participation is honored nationally: if you are a Delta Dental PPO or Premier dentist with your own state's Delta company, you are treated as in network for Delta Dental of California patients too, at the applicable fee schedule.
Federal programs and AARP plans are processed by Delta Dental of California, wherever the patient lives. DeltaCare USA is a capitated DHMO: encounters are required within 30 days, and you select Delta Dental Insurance Company as the payer for those claims.
Adjustments go through Provider Tools under My claims, Claim adjustment, within 21 days, or on the paper Provider Inquiry Form. Resubmissions and disputes go to P.O. Box 997330, Sacramento, CA 95899-7330, and disputes are taken only after an adjustment was attempted. Delta Dental of California aims to resolve them in writing within 45 working days.
Attachments: up to 5 files per claim, 5 MB in total, as PDF, JPG, GIF or TIF. Requests for records are due within 7 calendar days. Delta Dental of California and its affiliates make electronic payment the standard from January 1, 2027.
PPO versus Premier: PPO dentists are paid PPO fees. Premier dentists are paid Premier or PPO fees under a PPO plan, and cannot charge PPO members more than the PPO fee.
Most Delta Dental claims that come back unpaid were sent to the wrong member company, sent under the wrong payer ID, or hit a frequency limit nobody checked. Verify the company, plan type (PPO, Premier, DHMO or individual) and frequencies before the visit. The Delta Dental claims guide covers national rules, and our verification service does this for every patient.
