D7280 is the CDT code for the surgical exposure of an unerupted tooth — making an incision, reflecting the tissue, and removing bone as needed to expose the crown of an impacted tooth that is not intended to be extracted. It is typically performed to aid orthodontic treatment.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D7280 Code
Report D7280 when a tooth has failed to erupt and the dentist or surgeon surgically exposes its crown — incising and reflecting tissue and removing bone as needed — so the tooth can be brought into the arch, usually orthodontically. The tooth is not being extracted; it is being uncovered to save it. The most common example is an impacted maxillary canine guided into place with braces.
Distinguish it from related codes:
- D7280 exposes an unerupted tooth; the impaction extraction codes (D7220, D7230, D7240) remove an impacted tooth.
- Bonding a bracket or attachment to the exposed tooth, or placing an orthodontic device, may be reported under separate codes per payer rules.
- Surgical exposure with attachment of an orthodontic device is sometimes coded differently — confirm the specific scenario against the descriptor.
Documentation & Clinical Scenarios
Because D7280 is orthodontically driven, coordination and documentation matter:
- Tooth number (often an impacted canine) and the orthodontic referral / treatment plan explaining the purpose.
- A radiograph (panoramic, periapical, or CBCT) showing the unerupted tooth's position.
- An operative narrative documenting the incision, tissue reflection, and any bone removal to expose the crown — with the tooth left in place.
- Coordination notes with the referring orthodontist.
The chart should make clear the goal is exposure to aid eruption, not removal, so the procedure is not mistaken for an extraction.
Insurance & Billing Tips
- Verify benefits first. Confirm coverage for surgical exposure and how it interacts with orthodontic benefits, which are often a separate plan provision.
- Tie it to the ortho plan. A referral and treatment plan supporting the exposure strengthen medical necessity.
- Watch ortho exclusions. Some plans limit or exclude orthodontically related surgery; check before scheduling.
- Bill attachments separately. Any bonded bracket, chain, or orthodontic device follows its own code per payer rules.
- Read the EOB and appeal. If denied as "orthodontic," the surgical narrative and referral can support reconsideration.
Example Case
A 13-year-old in orthodontic treatment has an impacted maxillary canine that has not erupted; the orthodontist refers the patient for surgical exposure. A CBCT confirms the position of tooth #6. The surgeon incises and reflects the tissue, removes a small amount of overlying bone to expose the crown, and leaves the tooth in place for the orthodontist to guide into the arch — reported as D7280, with the imaging, an operative narrative, and the orthodontic referral. Any bonded attachment is billed under its own code. Because the exposure was tied to the orthodontic plan and documented, the claim is handled correctly.

Frequently Asked Questions
How is D7280 different from the impacted-tooth extraction codes?
The intent is opposite. The impaction codes — D7220 (soft tissue), D7230 (partially bony), and D7240 (completely bony) — describe removing an impacted tooth. D7280 describes exposing an unerupted tooth that is not being extracted, so it can be guided into place, usually orthodontically. Coding an exposure as an extraction (or the reverse) misrepresents the procedure and will not match the operative note, which should state clearly that the tooth was left in place.
Does D7280 include bonding a bracket or orthodontic attachment?
Not necessarily. D7280 covers the surgical exposure — incision, tissue reflection, and bone removal to uncover the crown. Bonding a bracket, chain, or other orthodontic attachment to the exposed tooth, or placing an orthodontic device, is often reported under a separate code, and rules vary by payer. Confirm how your specific carrier wants the attachment reported, and document each step so the exposure and any attachment are clearly distinguished.
Is D7280 covered by dental or orthodontic benefits?
It can fall in a gray area. The surgical exposure is a dental procedure, but because it serves orthodontic treatment, some plans treat it under orthodontic benefits or apply orthodontic exclusions. Verify how the patient's plan handles surgical exposure tied to orthodontics before scheduling, and tie the claim to the orthodontic referral and treatment plan. Checking this in advance prevents surprise denials based on an orthodontic exclusion.
Does D7280 require pre-authorization?
A pre-treatment estimate is often advisable because coverage for orthodontically related surgery varies and some plans limit it. Verify benefits, confirm how surgical exposure interacts with any orthodontic provision, and submit the referral, treatment plan, and imaging with the request. Establishing coverage and the orthodontic rationale up front reduces the chance of a denial or an unexpected balance for the family.
