What 39402 covers

A thoracic surgeon advances a mediastinoscope through an incision at the base of the neck to reach mediastinal lymph nodes and obtain tissue for pathology. A common use is sampling nodes to stage lung cancer; mediastinal lymphadenopathy or suspected lymphoma may also prompt tissue diagnosis. The service is typically performed in a hospital operating room under anesthesia.

Report the code when lymph node tissue is sampled through the mediastinoscopic approach; the biopsy is part of the service, rather than a separate biopsy charge for those nodes. The operative report should identify the approach and sampled nodal sites. The 0-day global period includes same-day preoperative and postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

39402 billing questions

How is this distinguished from 39401?

Use 39402 when mediastinoscopy is used to biopsy mediastinal lymph nodes. Code 39401 is associated with mediastinal biopsy rather than lymph node biopsy.

Can the sampled lymph node biopsy be billed separately?

No. The lymph node sampling is included in the mediastinoscopic service; do not report a separate biopsy charge for tissue obtained through this procedure.

What documentation supports reporting 39402?

The operative report should establish the mediastinoscopic approach and identify the mediastinal lymph node sites sampled.

Should modifier 50 be appended when nodes on both sides are sampled?

No. Modifier 50 is inappropriate for this code, even when the operative report describes sampling on both sides.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 39402. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
