D7280 Dental Code: Exposure of an Unerupted Tooth Guide

What D7280 covers

D7280 reports the surgical exposure of an unerupted or impacted tooth. The surgeon reflects a soft tissue flap, removes overlying bone when the tooth is covered by bone, and uncovers the crown so the tooth can erupt on its own or be moved into position by an orthodontist. The most common case is a maxillary canine that failed to erupt, though the code applies to any unerupted tooth being uncovered to aid eruption.

The code covers the exposure only. It does not include the orthodontic attachment or the removal of the tooth.

It does not cover:

• Bonding a bracket, button, or chain to the exposed tooth for orthodontic traction. That is D7283.
• Mobilizing (luxating) an erupted or malpositioned tooth to aid eruption. That is D7282.
• Surgically repositioning a tooth in the arch. That is D7290.
• Removing gum tissue over a partially erupted tooth for hygiene or symptom relief (operculectomy). That is D7971.
• Removing the tooth. Impaction removal is D7220 (soft tissue), D7230 (partially bony), or D7240 (completely bony).

Exposure versus removal

D7280 and the D72xx impaction codes uncover the same kind of buried tooth, so the code turns on why the surgeon is uncovering it. D7280 uncovers a tooth to keep and erupt it. The impaction codes uncover a tooth to remove it.

• D7280 exposes the tooth to aid its eruption or orthodontic movement. The tooth stays.
• D7220, D7230, D7240 remove an impacted tooth. The tooth goes.

A surgeon uncovering an impacted canine so ortho can pull it down bills D7280. A surgeon uncovering an impacted third molar to deliver it bills an impaction removal code. The access can look identical on both. The code reports why the tooth was uncovered.

D7280 and D7283 at the same visit

Most orthodontic exposures include bonding an attachment while the tooth is uncovered, so the surgeon can hand the orthodontist a chain to pull on. That attachment is D7283, the placement of a device that gives the orthodontist something to pull an impacted tooth into the arch with. It is a second procedure on top of the exposure.

Whether both pay is plan-dependent. Some plans allow the exposure and the attachment as separate benefits. Some bundle the attachment into the exposure. Some route D7283 to the orthodontic benefit because it is part of moving the tooth. Verify the pairing rule for the specific plan, and only report D7283 when a device was actually bonded.

When to bill D7280

Bill D7280 when:

• An unerupted or impacted tooth is surgically uncovered so it can erupt or be moved into the arch.
• The tooth is being kept, not removed.
• A flap was reflected, and bone was removed if the tooth was under bone, to expose the crown.

Do not bill D7280 for:

• Placing the orthodontic attachment. Use D7283.
• Loosening an erupted but stuck tooth. Use D7282.
• Excising inflamed tissue over a partially erupted tooth. Use D7971.
• Removing the tooth. Use the D7220, D7230, or D7240 impaction code that matches the bone coverage.

Top reasons D7280 gets denied or downgraded

1. Treated as orthodontic and routed to ortho coverage. Some plans consider exposure part of the ortho case and pay it against the orthodontic benefit or an ortho exclusion rather than the surgical benefit. A pre-authorization and a narrative tying the exposure to a documented impaction is the defense. Plan-dependent.
2. No pre-authorization on file. Many plans require prior authorization for surgical exposure. Without it, the claim pends or denies pending review.
3. Attachment confusion. The office bills only D7280 when a device was bonded, leaving D7283 unbilled, or bills D7283 when no attachment was actually placed. The claim should mirror what was done.
4. Coverage exclusion for impacted teeth. A small number of plans exclude treatment of impacted teeth or limit it to symptomatic cases. The denial reads as a plan exclusion, and the patient owes the fee.
5. Missing radiograph. No film showing the impacted tooth’s position. The carrier cannot confirm the tooth was unerupted.

Documentation that supports the claim

The claim is stronger with:

• A radiograph, often panoramic or a CBCT view, showing the tooth impacted and unerupted.
• An operative note recording the flap, any bone removal, and the exposure of the crown.
• The clinical purpose: exposure to aid eruption or to allow orthodontic traction.
• A pre-authorization number when the plan requires one.

For the patient record, document:

• The tooth number and that it was unerupted or impacted.
• The flap and any bone removed to reach the crown.
• Whether an attachment was bonded (which supports a separate D7283 line).
• The referral relationship with the treating orthodontist.

Example case

A 13-year-old established patient has an impacted upper-left canine (tooth #11) that has not erupted, confirmed on a panoramic film and a CBCT. The orthodontist refers the patient for surgical exposure with an attachment so the canine can be pulled into the arch. The surgeon reflects a flap, removes a small amount of overlying bone, uncovers the crown, and bonds a bracket with a gold chain.

Billing steps:

1. Verify the surgical benefit and confirm whether the plan wants a pre-authorization for exposure of an impacted tooth. Submit the pre-auth with the film.
2. Confirm how the plan handles the exposure-plus-attachment pair, so the patient hears the out-of-pocket picture before surgery.
3. Report D7280 for the exposure and D7283 for the bonded attachment on the same claim, with the tooth number.
4. Attach the radiograph and the operative note recording the flap, the bone removal, and the device placement.
5. Post the carrier’s payment. If the plan routed the exposure to the orthodontic benefit or excluded it, work the patient balance and, where warranted, appeal with the impaction documentation.

What to get right in your PMS

1. Code exposure by purpose, not by access. Uncovering a tooth to keep and erupt it is D7280. Uncovering a tooth to remove it is a D72xx impaction code.
2. Bill the attachment separately when a device is placed. D7283 is its own procedure. Do not fold it silently into D7280, and do not report it when nothing was bonded.
3. Check the pre-authorization requirement before surgery. Exposure of an impacted tooth pends or denies without the prior auth many plans require.
4. Attach the film. A radiograph showing the impacted, unerupted tooth supports the code and answers the reviewer’s first question.
5. Confirm the benefit bucket. Verify whether the plan pays exposure under the surgical benefit or the orthodontic benefit, so the estimate matches the EOB.
