What 53661 covers

This service is a repeat dilation of the female urethra, generally performed by a urologist or other qualified clinician using a dilator to widen the urethral channel. It may be performed in an office or facility when a patient returns for further treatment after an earlier dilation. The service addresses the urethra itself; documentation should support the reason for repeat treatment and the procedure performed.

Select this code for a subsequent female urethral dilation, rather than the initial or complicated service. Record the indication, relevant findings, and that dilation was carried out. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one 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 service, and co-surgeons and team surgery are not permitted.

53661 billing questions

How does this differ from 53660?

53661 is for a subsequent female urethral dilation; 53660 is the initial service in that code family.

When would 53665 be considered instead?

Use 53665 when the service meets the code family’s criteria for a complicated female urethral dilation, rather than a subsequent routine dilation.

How is this distinguished from 53621?

53621 is in the female urethral-stricture dilation family. Choose between the codes based on the documented service and applicable code-family criteria, not simply because dilation is repeated.

Is same-day care included in the procedure payment?

Yes. The 0-day global period includes same-day preoperative and postoperative care.

Can modifier 50 be reported?

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

The highest-valued procedure is paid in full; other procedures in the session are subject to the standard 50% multiple-procedure reduction.

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.
