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

What 39401 covers

A thoracic surgeon typically performs this procedure in an operating room, advancing a mediastinoscope through an incision at the base of the neck to reach and biopsy a mediastinal mass or other mediastinal tissue. The approach provides access to tissue behind the sternum for diagnostic evaluation, including in patients being assessed for a mediastinal lesion. The biopsy is part of the reported service.

Choose this code for mediastinal tissue or mass biopsy; use the lymph-node biopsy code when the sampled targets are mediastinal lymph nodes. The operative report should identify the mediastinal target and document the scope-guided biopsy. The 0-day global period includes same-day preoperative and postoperative care. 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 for this service. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
