What 54100 covers

A urologist or other qualified clinician takes a tissue sample from the penis to investigate a finding such as a persistent ulcer, atypical plaque, or suspected neoplasm. The procedure is commonly performed in an office or outpatient setting, often with local anesthesia. The tissue is sent for microscopic examination to help establish a diagnosis; this code represents the biopsy, not therapeutic removal of a lesion.

Report this code for a penile biopsy that is not the deeper sampling represented by 54105. The record should identify the sampled site, the lesion or clinical concern, and the biopsy performed. Same-day preoperative and postoperative care is included in this 0-day global period. If other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% multiple-procedure reduction. Do not append modifier 50; CMS treats bilateral adjustment as inappropriate for this code. Medicare does not pay an assistant at surgery for this service, and co-surgeon and team-surgery reporting 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.

How to choose

54105Penile biopsy
54100 describes a penile biopsy that is not deep; 54105 is the sibling code for deep penile tissue sampling.
54110Penile lesion treatment
54100 obtains tissue for diagnosis. Use the applicable lesion-treatment code when the service treats the penile lesion rather than sampling it.
54120Penile surgery
54100 is a diagnostic tissue-sampling service. 54120 describes partial removal of the penis, a substantially more extensive therapeutic operation.

54100 billing questions

How is 54100 distinguished from 54105?

Use 54100 for a penile biopsy that is not deep. Use 54105 when the documented service is a deep penile biopsy.

Can the lesion be removed instead of biopsied?

This code describes tissue sampling for diagnosis, not treatment of the lesion. When the service treats a penile lesion rather than obtaining a diagnostic sample, consider the applicable lesion-treatment code, such as 54110.

Is the pathology examination included?

The biopsy code represents obtaining the tissue. A laboratory or pathologist may separately report the histopathology service, such as 88305, when performed.

Should modifier 50 be reported for multiple penile biopsy sites?

No. CMS identifies bilateral adjustment as inappropriate for this code, so do not append modifier 50.

How are same-session procedures paid?

When other procedures are performed in the same session, the highest-valued procedure is paid in full and the remaining procedures are subject to the standard 50% multiple-procedure reduction.

Can an assistant or co-surgeon be reported?

Medicare does not pay an assistant at surgery for 54100. 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.
