Delta Dental Fax Number — Claims, Predeterminations, and Appeals

Delta Dental operates through independent member companies organized by state, so the fax you need depends on which Delta Dental entity administers the plan on the member's card. A predetermination or pre-treatment estimate goes to the fax line on the predetermination form for that state's plan, and claims or appeals use the number on the claim form or denial notice. Dental offices confirm current fax lines through the Delta Dental provider portal for their region, while members find contacts on the back of the ID card. Because a Delta Dental plan in one state is a separate company from another, always match the fax line to the specific plan.

What You Can Fax to Delta Dental

  • Dental claim forms and attachments
  • Predetermination and pre-treatment estimate requests
  • Appeals of a denied or reduced benefit
  • Coordination-of-benefits and dual-coverage forms
  • X-rays, periodontal charts, and narrative documentation
Tip: Dental claims and records are health information, so fax them through a HIPAA-eligible service and label every page with the subscriber ID, patient name, and date of birth so attachments like x-rays stay matched to the claim. Send FAX Mail's HIPAA-eligible Business plan ($79.99/month) works for this and returns a transmission receipt you can keep as proof the claim or predetermination reached the correct Delta Dental company before its deadline. Reference the claim or predetermination number on the cover sheet for accurate routing.

Faxing to Delta Dental — FAQ

Delta Dental is a network of independent, state-based member companies rather than one national office, so each administers its own claims and publishes its own fax lines. Identify which Delta Dental company appears on the member card, then use that company's forms.

Complete the predetermination or pre-treatment estimate form for the patient's Delta Dental plan and fax it to the line in the form's instructions, attaching supporting x-rays or charts. A predetermination is not a claim, so use the fax line the estimate form specifies rather than the claims line.

The appeal window and the fax line are stated on the Delta Dental Explanation of Benefits or denial notice for that claim. Fax your appeal before the listed date and keep the delivery confirmation as evidence you filed on time.

Yes, radiographs and periodontal charting are commonly faxed as claim attachments, and they should go to the same line as the claim they support. Send them at readable resolution and label each page so the images stay tied to the correct patient and claim.
