When to Use

Use S557 when performing a primary surgical release of adhesions specifically involving the urethra and bladder neck area.
Use this code for isolated lysis of urethrovesical adhesions where no other concurrent surgical procedure is performed, as it is restricted to sole-procedure billing.

Common Pitfalls

Attempting to bill S557 alongside other urological procedures will result in automatic rejection, as the Schedule of Benefits mandates it be the sole operative procedure.
Failure to document the specific anatomical location of the lysis can lead to audit scrutiny, as the code is specific to the urethrovesical junction.

Billing Tips

Ensure the claim is submitted as a standalone procedure; if you perform a more comprehensive procedure (e.g., cystourethroplasty), bill that primary code instead of S557.
