D7280 is the CDT code for surgical exposure of an unerupted tooth. The surgeon cuts through gingival tissue and, when necessary, removes overlying bone to uncover a tooth that has failed to erupt into the arch. The exposure is most often performed to allow an orthodontist to bond an attachment and guide the tooth into its correct position using orthodontic traction.

Get help with D7280 claims →The most common indication. A palatally or labially impacted maxillary canine is uncovered surgically so an orthodontic bracket and chain or button can be bonded to guide the tooth into the arch. The tooth remains in place.
When a maxillary central or lateral incisor is blocked or ectopic and cannot erupt naturally, surgical exposure and bracket placement allows orthodontic alignment without extraction.
Premolars, mandibular canines, or other teeth that are impacted but viable may be exposed for orthodontic bracketing when the treatment plan calls for guided eruption rather than removal.
Do NOT use D7280 for: Removal of an impacted tooth (use D7220, D7230, or D7240 depending on impaction level). Simple soft tissue procedures that do not involve an unerupted tooth. Incision and drainage procedures (use D7510). The defining clinical feature of D7280 is that the tooth is intentionally left in place and exposed for future guided eruption or bracketing.
Some payers categorize D7280 under orthodontic benefits rather than surgical benefits. This triggers orthodontic lifetime maximums, age limits, or waiting periods that do not apply to oral surgery claims. D7280 is an oral surgery CDT code, not an orthodontic code. Appeal miscategorized claims with a written explanation that the code represents a surgical procedure performed by a licensed oral surgeon or periodontist, not orthodontic treatment.
The claim must be supported by radiographic evidence confirming the tooth is unerupted and requires surgical exposure. A panoramic radiograph, CBCT, or periapical film showing the impacted tooth position is essential. Without it, payers have no basis to confirm the diagnosis, and the claim will be pended or denied for lack of clinical justification.
Many payers require documentation of an active orthodontic treatment plan as justification for the surgical exposure. A note stating the patient is in orthodontic treatment or that an orthodontist has referred for surgical exposure, with a treatment plan on file, significantly strengthens the claim. Exposure without a documented orthodontic goal may be questioned as clinically unjustified.
Some plans exclude surgical exposure of unerupted teeth or apply annual or lifetime limits that reduce reimbursement. Always verify the patient's specific plan before treatment. Inform the patient of any expected out-of-pocket cost if coverage is limited. Pre-authorization is advisable on plans that cover D7280 as it often requires documentation review before approval.
A panoramic radiograph, periapical film, or CBCT clearly showing the unerupted tooth position, its relationship to adjacent teeth, and the overlying tissue. The radiograph is the primary clinical justification for the exposure procedure.
Document the tooth involved, the type of impaction (soft tissue only vs. partial or full bony coverage), the surgical technique used (incision, flap design, bone removal if any), whether a bracket or chain was bonded at the time of exposure, and the wound closure method.
Include documentation from the referring orthodontist or a note in the patient chart confirming the patient is under or planning orthodontic treatment. The orthodontic treatment plan and referral letter support clinical necessity and help distinguish D7280 from an extraction.
Clearly identify the tooth by number or name in the claim and operative note. State the diagnosis: impacted tooth, failed eruption, or ectopic position. Match the tooth identification on the claim exactly with the radiograph and operative note.
Verify the patient's plan before scheduling. Plans that cover D7280 often require pre-authorization with radiographs and a brief narrative. Submit the pre-auth request in advance and retain the authorization number for the claim.

Learn about our billing servicesD7280 is the CDT code for surgical exposure of an unerupted tooth. The surgeon uncovers a tooth that has not erupted into the arch so that an orthodontist can bond a bracket and apply traction to guide it into position. The tooth is preserved, not removed.
D7280 is most commonly used for palatally or labially impacted maxillary canines. It is also used for ectopic or blocked maxillary incisors, premolars, and mandibular canines when orthodontic guided eruption is the treatment approach.
D7280 is an oral surgery CDT code billed by the surgeon who performs the exposure, not an orthodontic code. The surgeon's claim and the orthodontist's claims are separate. Payers who reclassify D7280 as an orthodontic procedure are applying the code incorrectly.
Common reasons include the payer incorrectly classifying D7280 under orthodontic benefits, missing radiographic evidence of impaction, no coordinating orthodontic treatment plan on file, and plan exclusions or benefit limitations for surgical exposure procedures.
Many dental plans cover D7280 as an oral surgery benefit with appropriate documentation. Pre-authorization and radiographs showing the impacted tooth position significantly improve approval rates. Coverage terms and any applicable limitations vary by plan.
D7240 is for complete removal of a fully bony impacted tooth. D7280 is for surgical exposure of an unerupted tooth that stays in the mouth and is guided into position orthodontically. The key distinction is removal versus preservation with guided eruption.
