Appeal letter: missing tooth clause denial

An appeal letter template for a bridge, implant or partial denied under the missing tooth clause, when the tooth was lost after coverage began.

Updated November 11, 2026

The denial

The plan denied the bridge, implant or partial because the tooth was missing before the patient's coverage started.

Why plans deny it

The plan has a missing tooth clause and had no record of when the tooth came out.
The patient had other coverage with the same insurer before, and the dates were mixed up.

Is it worth appealing?

Worth appealing when the tooth came out after the coverage date, and you can show it. If it was missing before, the clause usually applies and the patient owes the fee.

What to send with the letter

The extraction record with its date, from your office or the office that did it
An X-ray from before the extraction, if there is one
Proof of prior continuous coverage, if the plan gives credit for it
A copy of the explanation of benefits

Before you send it

Send it before the deadline. The denial notice has to say how long you have and how to appeal. Employer plans that follow federal benefit claim rules give at least 180 days.
Send it to the appeals address or fax on the explanation of benefits, not the claims address.
The patient, or someone they authorize, has the right to appeal. Offices often send it for the patient; some insurers first ask for the patient's signed authorization form.
Keep a copy of everything you send and the date you sent it. If the appeal is denied, the plan has to explain why in writing.

For how plans pay this service and what to check before treatment, read the bridges billing guide.

A starting point, not legal advice. The plan's documents and the insurer decide what's paid.
