D7510 is the CDT code for incision and drainage of an intraoral soft tissue abscess. It applies when a fluctuant abscess within the oral soft tissues requires a surgical incision to establish drainage and relieve acute infection. This is a soft tissue procedure only; abscesses involving bone use a separate code. D7510 is one of the oral surgery codes that may also be billable to medical insurance depending on the clinical situation.

Get help with D7510 claims →Use D7510 when performing incision and drainage of a fluctuant, pus-containing abscess confined to intraoral soft tissue. The abscess must be clinically apparent, with a defined soft tissue swelling containing purulent material. A surgical incision is made to establish drainage and relieve the acute infection. This is not a periodontal procedure and should not be used for routine periodontal pockets.
Common clinical scenarios: Pericoronitis with associated soft tissue abscess around an erupting or impacted wisdom tooth. Vestibular abscess arising from a necrotic tooth with soft tissue spread. Dentoalveolar abscess that has dissected through bone and is now presenting as a soft tissue fluctuance. Abscess formation following a recent extraction or surgical procedure. Periodontal abscess with defined fluctuant soft tissue component requiring drainage.
Do NOT use D7510 for: Abscesses involving the bone (use D7511 for intraoral osseous abscess). Extraoral abscess drainage (use D7520). Simple periodontal debridement of an infected pocket without fluctuant abscess. Periapical abscess managed through root canal access (use endodontic codes). Cases where drainage is achieved solely through extraction without a separate I&D incision.
Medical billing note: D7510 procedures are among the oral surgery codes that may qualify for medical billing. When the abscess causes systemic symptoms, cellulitis, or represents an emergency condition, the treating provider may submit to the patient's medical plan using ICD-10 diagnosis codes. Coordinate with both dental and medical billing teams to avoid duplicate payment and comply with coordination of benefits rules.
The clinical note must clearly describe a fluctuant, pus-containing soft tissue swelling. Vague entries such as "infection present" or "swelling noted" do not adequately support the D7510 code. Document the location of the abscess, its size or extent, the presence of fluctuance on palpation, and any purulent discharge upon incision. These details are what payers look for when reviewing the claim.
Some payers consider I&D inherent to an extraction when both are performed on the same tooth on the same date. If the I&D is a clearly separate and distinct procedure, document it as such. Describe the I&D incision separately from the extraction technique in the operative note. If the abscess is at a different site from the extracted tooth, note that clearly. Appeals that include a detailed narrative separating the two procedures have a higher success rate.
D7510 is only for intraoral soft tissue abscesses. If the abscess involves bone, D7511 is the correct code. If drainage is extraoral, D7520 applies. Billing D7510 when the clinical record or radiograph indicates osseous involvement leads to denial or audit. Review your documentation and radiographs to confirm the abscess is confined to soft tissue before coding D7510.
Claims submitted without a supporting ICD-10 diagnosis code, or with a diagnosis that does not match the procedure, are frequently denied. Select an ICD-10 code that accurately reflects the source and location of the infection. The diagnosis must match the procedure code. If you are billing to medical, the diagnosis code selection is especially important because medical payers use it to determine coverage eligibility.
Document the presence of a fluctuant, pus-containing intraoral swelling. Include tooth number or anatomic location, clinical size or extent, and findings on palpation. "Fluctuance noted on palpation of the buccal vestibule at tooth #19" is the level of specificity required.
Confirm that an incision was made, drainage was established, and the wound was irrigated. Note the amount and character of the discharge if recorded. This confirms that D7510 is the correct code and not a simpler approach such as periodontal curettage or extraction drainage.
If radiographs were taken, note whether they show any osseous involvement. D7510 requires that the abscess be confined to soft tissue. If bone is involved, D7511 is the appropriate code. Document this distinction explicitly in the clinical note.
Select and record the appropriate ICD-10 code for the type and location of the abscess. Common codes include K12.2, K04.7, and K05.20. The diagnosis must be consistent with the procedure description and any radiographic findings.
While not always required for a soft tissue abscess, a periapical radiograph helps confirm the source of infection and rule out bony involvement. Include available radiographs with the claim or have them ready for review if the claim is audited or appealed.

Learn about our billing servicesD7510 is the CDT code for incision and drainage of an intraoral soft tissue abscess. A surgical incision is made through the soft tissue to release purulent material and establish drainage. It applies to soft tissue only, not to osseous or extraoral abscesses.
In many cases, yes. Oral abscesses can present as medical emergencies and may be billed to medical insurance using ICD-10 codes such as K12.2. When systemic involvement, cellulitis, or emergency care is involved, medical billing is often appropriate. Coordinate with the patient's medical plan and avoid duplicate billing.
D7510 is for intraoral soft tissue abscesses where no bone is involved. D7511 is for intraoral osseous abscesses, where the infection involves underlying bone and osseous access is required. The presence or absence of bony involvement is the key distinction.
Yes, when the I&D is a genuinely separate procedure. Document the abscess and the I&D incision distinctly from the extraction. If payers bundle the claim, submit an appeal with a narrative separating the procedures and confirming they addressed different sites or required distinct surgical steps.
Common reasons include vague or missing documentation of the fluctuant abscess, bundling with a same-day extraction, using D7510 when the abscess involves bone (should be D7511), and incorrect or missing ICD-10 diagnosis codes.
Common ICD-10 diagnosis codes include K12.2 (cellulitis and abscess of mouth), K04.7 (periapical abscess without sinus), and K05.20 (aggressive periodontitis, unspecified). Select the code that best matches the specific source and anatomic location of the infection.
