Ask AI Bill This Code — Sign Up Free

A surgical procedure involving the percutaneous or retrograde removal of renal calculi from the kidney or upper urinary tract. The service fee is for the surgeon (suffix A), with separate calculations for assistant (suffix B, 6 base units) and anaesthetist (suffix C, 7 base units) services. Add-on code E759 is payable for stone disintegration, and E772 is payable for the removal of a staghorn calculus. See .

When to Use

Use Z627 for percutaneous or retrograde removal of renal calculi where the primary objective is the extraction of the stone.
Use Z627 in conjunction with E759 when the procedure involves stone disintegration (e.g., lithotripsy) as part of the removal process.
Use Z627 with E772 specifically for percutaneous removal of a staghorn calculus that fills the renal pelvis and extends into the calyces.

Common Pitfalls

Billing E772 without confirming the procedure was performed percutaneously, as this code is strictly restricted to percutaneous staghorn removal.
Failing to document the specific method of disintegration when claiming E759, which is a common trigger for audit inquiries.
Attempting to bill Z627 alongside other urological procedures without verifying if they are considered 'inclusive' under the General Preamble rules for surgical bundling.

Billing Tips

Ensure that the surgical assistant (suffix B) and anaesthetist (suffix C) claims are submitted with the appropriate base units (6 and 7 respectively) to avoid automatic rejection.
Always verify the patient's age at the time of the procedure to apply the correct age premium (e.g., AGE_PREMIUM_U16Y), as these are calculated as a percentage of the total surgical fee.
