What 41827 covers
This code describes surgical excision of a lesion involving the gum. It may be performed by an oral and maxillofacial surgeon, dentist, or another qualified clinician in an office or facility setting. The operative report should identify the gingival site, describe the lesion and the excision performed, and distinguish removal of the lesion from drainage or removal of a foreign material.
Choose this code based on the documented procedure and the applicable descriptor, not simply the lesion diagnosis. For nearby gum-lesion excision codes, confirm the specific descriptor before selecting a sibling code. The day-before preoperative visit and 90 days of related postoperative care are included in the global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
