D7280 is the CDT code for surgically uncovering an unerupted or impacted tooth so it can erupt or be pulled into the arch by orthodontics.
- When to use: The tooth is being kept, most often an impacted upper canine uncovered so the orthodontist can bring it into the arch.
- When not to use: A bonded bracket or chain is D7283, a stuck erupted tooth is D7282, and removing an impacted tooth is D7220, D7230, or D7240.
- Billing note: Many plans require pre-authorization for exposure, so submit it with the film and confirm whether the surgical or ortho benefit pays.
What D7280 covers
D7280 reports the surgical exposure of an unerupted or impacted tooth that is being kept. The surgeon reflects a soft tissue flap, removes overlying bone when the tooth is under 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 uncovered to aid eruption.
The code covers the exposure only. 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 inflamed 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 impaction removal codes uncover the same kind of buried tooth, so the code turns on why the surgeon is uncovering it, not on the access.
- 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 the impaction removal code that matches the bone coverage. The access can look identical on both.
D7280 and D7283 at the same visit
Most orthodontic exposures include bonding an attachment while the tooth is uncovered, so the orthodontist has a chain to pull the tooth into the arch. That attachment is D7283, a second procedure on top of the exposure. Report D7280 plus D7283 on separate lines, and report D7283 only when a device was actually bonded.
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.
Top reasons D7280 gets denied or downgraded
- 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.
- No pre-authorization on file. Many plans require prior authorization for surgical exposure. Without it, the claim pends or denies pending review.
- Attachment confusion. The office bills only D7280 when a device was bonded, leaving D7283 unbilled, or bills D7283 when no attachment was placed. The claim should mirror what was done.
- 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.
- Missing radiograph. With 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:
- Verify whether the plan pays exposure under the surgical or the orthodontic benefit, and whether it requires a pre-authorization for exposure of an impacted tooth. Submit the pre-auth with the film.
- Confirm how the plan handles the exposure-plus-attachment pair, so the patient knows the out-of-pocket cost before surgery.
- Report D7280 for the exposure and D7283 for the bonded attachment on the same claim, with the tooth number.
- Attach the radiograph and the operative note recording the flap, the bone removal, and the device placement.
- 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.
FAQs
- What is the difference between D7280 and D7283?
- D7280 is the surgical exposure that uncovers the crown of an unerupted tooth, removing overlying bone if needed. D7283 is placing an orthodontic attachment (a bracket, button, or chain) on that exposed tooth so the orthodontist can pull it into the arch. They are two distinct procedures that often happen at one visit.
- Can I bill D7280 and D7283 at the same visit?
- Often yes, because they are separate procedures, but coverage is plan-dependent. Some plans pay both, others bundle the attachment into the exposure fee or route D7283 to the orthodontic benefit. Verify the plan's rule before treatment, and document that a device was actually bonded when you report D7283.
- Is D7280 the code for removing an impacted tooth?
- No. D7280 uncovers an impacted tooth so it can stay and erupt. Removing an impacted tooth is D7220 for a soft tissue impaction, D7230 for partially bony, or D7240 for completely bony.
- Why did the carrier deny D7280 as orthodontic?
- Some plans treat exposure of an impacted tooth as part of the orthodontic case, so the claim lands against ortho coverage (or an ortho exclusion) instead of the oral-surgery benefit. This is plan language and varies by plan. A pre-authorization and a narrative tying the exposure to a documented impaction, not elective alignment, is the cleanest way to get ahead of it.
- What is the difference between D7280 and D7282?
- D7280 uncovers an unerupted tooth that is still covered by tissue or bone. D7282 mobilizes an erupted or malpositioned tooth to aid eruption, typically luxating a tooth that has stalled or ankylosed to free it for movement.
