CPT® Code 41015

The procedure described by CPT® Code 41015 involves the extraoral incision and drainage of an abscess, cyst, or hematoma located in the floor of the mouth, specifically within the sublingual space. The sublingual space is a deep fascial area situated beneath the tongue, while the surrounding spaces, including the submental, submandibular, and masticator spaces, are also relevant to this procedure. These spaces are defined by their anatomical boundaries, with the mandible forming the anterior and lateral limits, and the superficial layer of deep cervical fascia providing the inferior boundary. The submandibular approach is utilized for accessing these spaces, which involves incising through the skin and subcutaneous tissue to reach the submandibular space. Depending on the specific area affected, further dissection may be required to enter the sublingual, submental, or masticator spaces. The procedure entails exposing the abscess, cyst, or hematoma, followed by drainage and the placement of drains if necessary. This intervention is critical for alleviating symptoms associated with these conditions and preventing complications that may arise from untreated infections or fluid collections in these anatomical regions.
