D7410 is the CDT code for the excision of a benign (non-cancerous) oral lesion measuring up to 1.25 cm in diameter — the complete surgical removal of a small benign growth such as a fibroma, papilloma, or granuloma. Unlike a biopsy, the entire lesion is removed.
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 D7410 Code
Report D7410 when the surgeon completely excises a benign soft-tissue or ridge lesion that is 1.25 cm or smaller in diameter — common examples include fibromas, papillomas, and granulomas. This is an excision (the whole lesion is removed), not an incisional biopsy where only a portion is sampled.
Size and behavior are the two key variables. D7411 is the same excision for a benign lesion greater than 1.25 cm. If the lesion is malignant, the excision codes are D7440 (up to 1.25 cm) or D7441 (greater than 1.25 cm) instead. And if only a portion of the lesion is removed for diagnosis, the correct codes are the incisional biopsy codes D7286 (soft) or D7285 (hard), not D7410. Local anesthesia is generally included in D7410 and is not billed separately.
Documentation & Clinical Scenarios
Strong documentation supports the excision and the size threshold:
- Site and lesion type (for example, fibroma, papilloma, granuloma) and a clear benign clinical impression.
- Lesion diameter documented as 1.25 cm or smaller, since the size determines D7410 vs. D7411.
- A surgical narrative confirming complete excision of the lesion (not a partial biopsy).
- Pathology submission, when the specimen is sent for histopathologic confirmation.
The pathology laboratory analysis is billed separately when the excised specimen is submitted for examination. Local anesthesia is part of the excision and is not reported separately.
Insurance & Billing Tips
- Verify benefits first. Confirm coverage for benign-lesion excision and whether the plan adjudicates it under dental or medical.
- Document the size. Record the diameter — D7410 is for lesions up to 1.25 cm; larger lesions are D7411.
- Confirm excision vs. biopsy. Complete removal supports D7410; a partial sample points to an incisional biopsy code (D7285/D7286).
- Bill pathology separately. If the specimen goes to a lab, the histopathologic exam is its own line item.
- Don't bill local anesthesia separately. Local anesthesia is generally included in the excision.
Example Case
A patient has a small, firm, painless bump on the inside of the cheek that has been present for months — clinically consistent with an irritation fibroma about 0.8 cm across. The surgeon completely excises the lesion under local anesthesia and submits it to pathology to confirm the benign diagnosis. Because the entire benign lesion was removed and it measured under 1.25 cm, the excision is reported as D7410, with the diameter documented and the pathology analysis billed separately by the lab.

Frequently Asked Questions
How is D7410 different from D7411 and D7440?
The differences are size and behavior. D7410 is excision of a benign lesion up to 1.25 cm; D7411 is the same procedure for a benign lesion larger than 1.25 cm. If the lesion is malignant, you use D7440 (up to 1.25 cm) or D7441 (larger). So you need both the lesion's diameter and its benign-versus-malignant nature to choose correctly. Document the measured size and the clinical or pathologic diagnosis before billing.
Does D7410 include the pathology fee or count as a biopsy?
No on both. D7410 covers the surgical excision itself; if the specimen is sent for histopathologic examination, the laboratory analysis is billed separately. And D7410 is an excision — the entire lesion is removed — not an incisional biopsy. When only a portion of a lesion is sampled for diagnosis, the incisional biopsy codes D7285 (hard) or D7286 (soft) apply instead.
Is D7410 covered by dental or medical insurance?
It depends on the payer. Some carriers adjudicate lesion excisions under dental benefits, while others treat them as medically necessary and process them under the patient's medical plan. Verify coverage in advance and ask whether the claim should be cross-coded to medical with a CPT equivalent. Confirming the path before treatment reduces denials and surprise balances.
Does D7410 require pre-authorization?
Pre-authorization is not always required, but a pre-treatment estimate can be helpful, especially when coverage routes to medical. Submitting the lesion site, the documented diameter, and a narrative confirming complete excision of a benign lesion clarifies coverage and reduces the chance of a denial or a down-code to a smaller or different procedure.
