Timely filing limits

• Original claims: 12 months from date of treatment (some programs shorter)

• Appeals: 90 days from original submission (claim adjustment)

EFT and ERA enrollment

Sign in to Provider Tools and select the EFT and ERA icon; a voided check verifies banking details. Enroll each practice location separately. Providers outside this family's states enroll through their local Delta Dental. Enrollment takes 2-4 weeks. From January 1, 2027, paper checks carry a $15 weekly fee where state law allows. Help: providertools@delta.org.

Credentialing and network enrollment

Contact: 888-599-1771 (DataSpring Solutions Center, weekdays 8am-8pm ET); https://www1.deltadentalins.com/dentists/caqh-credentialing.html

Credentialing and re-credentialing are free through DataSpring, powered by CAQH. New users register, complete their profile and authorize Delta Dental to access it. Existing users should confirm global authorization is granted to Delta Dental, especially when re-credentialing is due.

Plan clauses to check during verification

Missing tooth clause

Whether a missing tooth clause applies depends on the group plan. Ask whether the plan excludes replacing teeth lost before coverage began, and note the answer before you present a bridge or implant. See how to spot the missing tooth clause.

Waiting periods

Waiting periods are set by the group plan. Confirm the waiting period for basic and major services and the patient's effective date.

Downgrades (alternate benefit)

Ask whether posterior composites are paid at the amalgam rate and whether crowns downgrade to a base-metal benefit, so the patient estimate is right the first time.

Frequency limits

Set per plan. Once a frequency limit or annual maximum is reached the patient owes the charges, but contracted dentists cannot bill above the patient portion Delta Dental determines.

Verification checklist for Delta Dental of California

• Use My Patients or Submit Claim in Provider Tools for real-time eligibility, benefits and claim status; Delta Dental promotes this as faster than phone.

• Confirm which entity insures the patient (Delta Dental of California, Delta Dental Insurance Company or the Mid-Atlantic group); each has its own P.O. Box and payer ID.

• To contest a decision, file a claim adjustment in Provider Tools within 90 days. A Provider Dispute (Provider Inquiry Form) is accepted only after an adjustment attempt.

• For DeltaCare USA patients, use the separate DeltaCare eligibility and benefits flow in Provider Tools; DeltaCare uses capitated primary care dentists.

• For FEDVIP, VADIP and active-duty patients, call the 24-hour automated dental-office line, 844-825-8111.

• Without Provider Tools, the automated phone system can fax back eligibility and benefits. Have the practice TIN, patient ID and date of birth ready.

• Record the representative's name, the call reference number and the date for every phone verification.
