D7286 is the CDT code for an incisional biopsy of soft oral tissue — the surgical removal of a portion of a soft-tissue lesion (gingiva, cheek, tongue, lip, or palate) for laboratory examination. Only part of the lesion is sampled to obtain a diagnosis, not the entire lesion.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D7286 Code
Report D7286 when a representative portion of a soft-tissue lesion is removed and submitted to pathology — typically when the nature of the lesion is uncertain or malignancy is suspected and the clinician needs a histopathologic diagnosis before definitive treatment.
Do not confuse D7286 with D7285 (incisional biopsy of oral tissue — hard), which is for bone or tooth. The soft-versus-hard distinction is the key choice. D7286 is also distinct from an excisional biopsy, where the whole lesion is removed — benign excisions are reported with D7410/D7411 and malignant excisions with D7440/D7441. If the entire lesion comes out, an excision code is usually more accurate than this incisional code.
Documentation & Clinical Scenarios
Clean documentation supports both the diagnosis and the claim:
- Site and description of the lesion (location, approximate size, color, surface, duration).
- The clinical indication — why a biopsy was warranted (suspicious, non-healing, or undiagnosed lesion).
- A surgical narrative confirming that a portion (incisional) of the soft-tissue lesion was removed and sent to pathology.
- Clinical photographs when available, which strengthen medical-necessity documentation.
The pathology laboratory analysis is billed separately from D7286 — this code covers only the surgical act of obtaining the specimen, not the histopathologic exam. Local anesthesia is generally considered part of the procedure.
Insurance & Billing Tips
- Verify benefits first. Confirm whether soft-tissue biopsies are covered and whether the plan adjudicates them under dental or medical — many payers cross-code biopsies to medical.
- Bill pathology separately. The lab's interpretation is its own line item, not part of D7286.
- Confirm "incisional" vs. "excisional." A partial sample supports D7286; complete removal of the lesion points to an excision code.
- Attach a narrative and photos. A short narrative and clinical images describing a suspicious or non-healing lesion support medical necessity and reduce denials.
- Check medical cross-coding. When the biopsy is medically necessary, the payer may require submission to medical with the appropriate CPT crosswalk first.
Example Case
A 47-year-old patient presents with a persistent white-and-red patch on the lateral border of the tongue that has not resolved in several weeks. Because malignancy must be ruled out, the surgeon removes a representative portion of the lesion under local anesthesia and submits it to an oral pathology lab. The surgical removal of the partial soft-tissue specimen is reported as D7286, with a narrative and clinical photo attached. The pathologist's interpretation is billed separately by the lab.

Frequently Asked Questions
How is D7286 different from D7285?
Both are incisional biopsies, but the tissue type differs. D7286 is for soft oral tissue — gingiva, cheek, tongue, lip, or palate. D7285 is for hard tissue, meaning bone or tooth, such as an osseous or intra-osseous lesion. The right code depends entirely on whether the sampled tissue is soft or hard, so confirm the lesion type before billing. Choosing the wrong one is a frequent cause of denials.
Does D7286 include the pathology lab fee or the full excision?
No. D7286 covers only the surgical act of taking a portion of the soft-tissue lesion. The pathology laboratory's histopathologic examination is a separate service, usually billed by the lab. And because this is an incisional biopsy, it does not include complete removal of the lesion — if the whole lesion is excised, an excision code such as D7410 or D7440 is generally more accurate.
Is D7286 covered by dental or medical insurance?
It depends on the payer. Many carriers treat oral biopsies as medically necessary and adjudicate them under the patient's medical plan, while others process them under dental. Verify coverage in advance and ask whether the payer wants the claim cross-coded to medical with a CPT equivalent. Confirming the path before treatment reduces denials and unexpected patient balances.
Does D7286 require pre-authorization?
Pre-authorization is not always required, but a pre-treatment estimate is often recommended because payers review biopsies closely. Submitting the clinical indication, a short narrative, and any photographs confirms coverage, clarifies whether the claim routes to dental or medical, and reduces the chance of a denial on a procedure carriers commonly scrutinize.
