Excision

Excision in dentistry refers to the surgical cutting away and removal of tissue from the oral cavity. Common indications include removing suspicious soft tissue lesions from the tongue, cheeks, lips, or gums, excising hyperplastic tissue, and performing biopsies for pathological evaluation. The procedure is typically performed under local anesthesia in the dental office and may require sutures depending on the size and depth of the tissue removed. Excised specimens are routinely sent to an oral pathology laboratory for microscopic examination, making excisional biopsy a critical tool in the early detection of oral cancer and other pathological conditions.

CDT coding for excision procedures falls primarily within the D7000 surgical series, with specific codes determined by the type, size, and location of the lesion. Excision of benign tumors uses codes D7410 through D7415 based on lesion diameter, while excision of malignant tumors falls under D7440 through D7465. Soft tissue biopsy without complete removal is coded separately as D7286. Selecting the correct code requires accurate measurement and documentation of the excised tissue, as payers will compare the code submitted against the clinical narrative and pathology report.

In revenue cycle management, excision claims demand thorough documentation that includes the size, location, and clinical description of the tissue removed, the rationale for excision, and the pathology lab to which the specimen was submitted. Claims submitted without this documentation are routinely denied or pended for additional information. Additionally, excision procedures performed for medical indications such as suspected malignancy or pathology may be billable to medical insurance rather than or in addition to dental coverage. Practices that identify medical crossover opportunities and maintain follow-up systems to track pathology results and ensure timely patient notification maximize both clinical outcomes and revenue capture on these surgical cases.
