CPT code 53665: Urethral dilation, female, complicated2026 Medicare rate & RVUs

Medicare pays $33.07 for 53665 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 53665 covers

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.
