What 42800 covers

An otolaryngologist takes a tissue sample from an abnormal area of the pharynx for diagnostic examination. The service is used when inspection identifies a lesion or mucosal change that needs tissue diagnosis; the biopsy samples tissue rather than removing the lesion as definitive treatment. It may be performed in an office or an operating room, depending on access and the clinical circumstances.

Report the code when the documented service is a pharyngeal biopsy, not a biopsy of a nasopharyngeal lesion or therapeutic excision. The record should identify the pharyngeal site, the abnormality prompting sampling, and the tissue obtained. Medicare assigns a 10-day global period, which includes related postoperative visits during that period. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Do not use modifier 50 for bilateral adjustment. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

42800 billing questions

How does this differ from a nasopharyngeal biopsy?

Use 42800 for a biopsy in the pharynx. Codes 42804 and 42806 describe biopsies of the nasopharynx, so the documented site determines the choice.

Can this code represent complete removal of a pharyngeal lesion?

It represents tissue sampling for diagnosis, not therapeutic removal of the lesion. When the lesion is excised, consider 42808 if its service and site criteria are met.

How are other procedures in the same session paid?

Under the standard multiple procedure reduction, Medicare pays the highest-valued procedure in full and applies a 50% reduction to the others.

Should modifier 50 be used for biopsies on both sides?

No. Bilateral adjustment is inappropriate for this code's descriptor or anatomy; do not append modifier 50.

What documentation supports reporting this biopsy?

Document the pharyngeal site, the lesion or abnormality prompting the biopsy, and the tissue sampled. Related postoperative visits during the 10-day global period are included.

Can an assistant, co-surgeon, or surgical team be billed?

Medicare does not pay an assistant at surgery for this service. 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.
