What is the correct code for an injection procedure for ureteropyelography through an indwelling ureteral catheter?

The correct code for an injection procedure for ureteropyelography through an indwelling ureteral catheter is 50684. This code specifies the injection into the renal pelvis, which is essential for imaging purposes in ureteropyelography. This procedure involves the introduction of a contrast material through an indwelling catheter in the ureter, allowing for clear visualization of the urinary tract.

The specificity of the code highlights that it applies to procedures involving the ureter and renal pelvis, ensuring accurate identification for billing and documentation purposes. The selection of this code reflects awareness of the procedural details, specifically the access through an indwelling catheter, which differentiates it from other similar procedures within the coding system.

Other codes, while related to kidney or ureter procedures, do not represent the specific action of injecting contrast for imaging through an indwelling catheter. Each of those alternatives serves a different procedure or context, emphasizing the importance of selecting the most precise code that aligns with the documented procedure.
