Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 41100 covers

This service samples tissue from the front two-thirds of the tongue, from the tip through the body, for pathologic examination. An otolaryngologist, oral and maxillofacial surgeon, or other qualified clinician may perform it in an office or facility. Common reasons include evaluating a persistent tongue ulcer or a suspicious white or red mucosal patch. The biopsy obtains diagnostic tissue; it is not reported in place of an excision that removes the lesion.

Document the exact tongue site, the clinical concern, and the tissue obtained for examination. Choose the posterior-tongue biopsy code when the sampled site is in the back third, and use a floor-of-mouth code for tissue from that separate site. Medicare assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
