What 53621 covers

This code applies to a subsequent urethral stricture dilation in a female patient using sounds or dilators to widen the narrowed urethral passage. A urologist typically performs the procedure in an office or outpatient facility. It is distinct from dilation of a female urethra when a urethral stricture is not the condition being treated.

Select the subsequent-service code rather than the initial-service code based on where the dilation falls in the treatment sequence, not the stricture’s severity. Document the stricture, the patient’s anatomy, the dilation performed, and why this was a subsequent service. 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; assistant-at-surgery payment is restricted, and co-surgery and team-surgery payment are not permitted.

53621 billing questions

How does this differ from 53620?

53620 is the initial dilation code for a female urethral stricture. Use 53621 for a subsequent dilation in the treatment sequence.

Can 53621 be reported for a male patient?

No. This code is for subsequent dilation of a female urethral stricture; male stricture dilation is coded in the male-specific code series.

How does this differ from 53661?

53621 concerns a urethral stricture and a subsequent dilation. Code 53661 is in the separate series for female urethral dilation.

Should modifier 50 be appended?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

What same-day care is included?

The 0-day global period includes same-day preoperative and postoperative care. Other procedures performed in the same session may be subject to the standard multiple-procedure reduction.

What documentation supports reporting 53621?

Document the female patient’s urethral stricture, the dilation performed with sounds or dilators, and why the service is subsequent rather than initial.

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.
