What Is D8080 — Comprehensive Orthodontic Treatment for Adolescents?
D8080 is a CDT code in the Orthodontic category. It covers comprehensive orthodontic treatment for adolescents services and is used when the clinical record documents the appropriate indications for this procedure.

[ ] Clinical notes documenting the separate indications for both procedures

Billing Tips to Avoid Denial
1. Consultations (D9310) at ortho visits are billable
A professional consultation performed at an orthodontic appointment is separately billable when it involves evaluation for an issue outside the scope of the active orthodontic treatment.
2. Adjunctive anesthesia for ortho procedures has limited coverage
Local or sedation anesthesia for orthodontic procedures is not commonly covered. Verify plan benefits and document clinical necessity before billing.
3. Retainer delivery is not an adjunctive code
Retention is part of the orthodontic treatment plan and is included in the global ortho fee. Do not bill adjunctive codes for standard retention appointments.
4. Document the distinct clinical need for adjunctive services
The chart note must explain why the adjunctive service was necessary at the orthodontic appointment, separate from the orthodontic treatment itself.
