D7280Exposure of an Unerupted Tooth

What This Code Covers

D7280 covers the surgical exposure of an unerupted tooth to support its eruption or to allow an orthodontic bracket to be bonded to it. The procedure involves reflecting the gum tissue and removing any bone covering the tooth to expose its crown. This is commonly performed on impacted maxillary canines that have failed to erupt, allowing the orthodontist to guide the tooth into its correct position with braces. The code covers the surgical exposure only, not the orthodontic attachment.

Billing Guide

Bill this code when:

• An unerupted tooth is surgically exposed to support eruption or orthodontic treatment
• Gum tissue and/or bone is removed to uncover the tooth
• The goal is to preserve the tooth and guide it into position (not extract it)
• The tooth remains in the jaw after exposure (not removed)

Do not bill this code when:

• The tooth is being extracted. Use D7220-D7241 impaction codes
• An orthodontic bracket is bonded to the exposed tooth. Use D7283 if bracket placement is included
• The exposure is incidental to another surgical procedure
• The tooth has partially erupted and only needs soft tissue removal (may be D7220 or gingivectomy)

Insurance and Denial Prevention

Key Payer Rules:

• D7280 is typically covered under oral surgery benefits
• The code is separate from orthodontic treatment codes (D8000 series)
• Some payers require documentation that orthodontic treatment is planned
• If the tooth is being extracted rather than exposed, use impaction codes instead

Common Denials and How to Respond:

• Should be an extraction code - Clarify that the tooth was exposed, not removed. The goal is to preserve the tooth and guide it into alignment.
• No orthodontic treatment on file - Submit the orthodontic treatment plan showing that the exposed tooth will be tracked into position with braces.
• Not medically necessary - Document why the tooth needs to be exposed (failure to erupt, malposition) and the benefit of guiding it into the arch rather than extracting and replacing it.
