Drainage-Root Operation 9
Drainage is defined as taking or letting out fluids or gases from a body part. The drainage root operation is coded for both diagnostic and therapeutic drainage procedures. When a drainage procedure includes putting in a catheter, the sixth character of the code is the device value “drainage device.”
The qualifier “diagnostic” is available to identify drainage procedures that are biopsies. The qualifier is the seventh character of an ICD-10-PCS code.
Examples of drainage procedures include diagnostic paracentesis, thoracentesis, incision and drainage of abscess, chest tube placement, and Foley catheter placement.
