About 53665: Complicated female urethral dilation
Reports complicated urethral dilation in a female patient when the procedure involves circumstances beyond routine female urethral dilation.
A urologist or other qualified clinician uses urethral dilators to widen a narrowed female urethra when the dilation is complicated. The service may be performed in an office or facility setting. The record should explain the urethral problem and the circumstances that make the dilation complicated; the code is not selected simply because dilation is repeated.
Report 53665 for the complicated female procedure rather than routine female dilation, distinguishing it from initial and subsequent services in that code family. Document the indication, relevant anatomy or history, and work performed. Medicare assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% 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.

53665 billing questions
When should 53665 be selected instead of 53660 or 53661?
Use 53665 for complicated female urethral dilation. Codes 53660 and 53661 distinguish routine female dilation by initial versus subsequent service.
Does a repeat dilation qualify as complicated?
Not by itself. The documentation should describe the circumstances that make the procedure complicated, rather than relying only on the fact that dilation was performed before.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the 0-day global period affect same-day care?
Same-day preoperative and postoperative care is included in the procedure's global period.
Can an assistant or co-surgeon be billed for 53665?
Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
