If your insurance denies a dental claim: questions for the plan and office

Published October 20, 2026

In short

A denial is the plan's decision about what the contract pays, not a judgment that the treatment was unnecessary. Start with the explanation of benefits: find the denial reason or code, ask the plan in writing for the specific reason, the appeal steps and the deadline, and ask the dental office whether a narrative, x-rays, photographs or gum-measurement charting could support a corrected claim or an appeal.

Common denial groups

Questions for the plan

Exact reason and code; what documentation would change the decision; the appeal process and deadline; whether a second-level or external review exists.

Questions for the office

Was the claim complete; can you add a narrative, x-rays, photos or charting; will you resubmit or appeal; what is the deadline?

Keeping track

Dates of service, submission, denial and appeal; copies of everything; names of people you spoke with.
