About 41105: Posterior tongue biopsy
Reports tissue sampling from the posterior one-third of the tongue to evaluate a suspicious lesion or other abnormal tissue.
This service is a tissue sample taken from the posterior one-third of the tongue for diagnostic evaluation, such as investigation of a suspicious ulcer, mass, or mucosal change. An otolaryngologist, head-and-neck surgeon, or oral and maxillofacial surgeon may perform it in an office, procedure room, or operating room, depending on access and the patient’s needs. The sample is submitted for pathologic examination; this code describes the biopsy procedure, not the pathology interpretation.
Choose this code for a biopsy from the posterior tongue, rather than the anterior two-thirds or the floor of the mouth. The note should identify the sampled site and the lesion or abnormal tissue prompting the biopsy. It has a 10-day global period, so related postoperative visits during that period are included. When multiple procedures subject to the standard reduction are performed in the same session, the highest-valued is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery billing are not permitted.

41105 billing questions
How is 41105 distinguished from 41100?
41105 is for a biopsy of the posterior one-third of the tongue; 41100 is for the anterior two-thirds. The documentation should identify which part of the tongue was sampled.
Can 41105 be used for a floor-of-mouth biopsy?
No. A biopsy of the floor of the mouth is reported with 41108; 41105 is for the posterior tongue.
When would a tongue lesion excision code be more appropriate?
Use a biopsy code when tissue is sampled for diagnosis. When the lesion is removed rather than sampled, consider the applicable tongue lesion excision code, such as 41110.
Is modifier 50 appropriate for a biopsy of both sides of the tongue?
No. CMS identifies bilateral adjustment as inappropriate for this code, so do not append modifier 50.
Are related postoperative visits included?
Yes. Related postoperative visits during the 10-day global period are included in the procedure.
Can an assistant surgeon or co-surgeon be billed?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
