Which code reports open drainage of a perirenal abscess?

The code that reports open drainage of a perirenal abscess is 50020. This code is specifically designated for procedures involving the renal system, particularly addressing the drainage of an abscess that is located near the kidney (perirenal).

The term "open drainage" indicates that a surgical approach is employed to facilitate the removal of infected material or fluid from the abscess site. In this case, the procedure is directly linked to the perirenal area, which is consistent with the definition utilized in the coding guidelines for this code.

The other codes listed pertain to different anatomical regions or procedures. For example, 52275 relates to a procedure involving the bladder and prostatic urethra, 60650 addresses procedures outside the renal context, specifically for the male reproductive system, while 60300 involves surgical procedures in the urinary tract but not explicitly related to abscess drainage. Thus, 50020 appropriately captures the intent and nature of the procedure being described.
