W The Anatomical Regions, General body system is identified by the character “W” in the 2nd character position and grouped within the Medical and Surgical section of the ICD-10-PCS coding structure. The 2nd character of an ICD-10-PCS code defines the particular body system or general physiological system or anatomical region involved.

Anatomical Regions, General
Modifying the anatomic structure of a body part without affecting the function of the body part — Principal purpose is to improve appearance
Altering the route of passage of the contents of a tubular body part — Rerouting contents of a body part to a downstream area of the normal route, to a similar route and body part, or to an abnormal route and dissimilar body part. Includes one or more anastomoses, with or without the use of a device
Taking out or off a device from a body part and putting back an identical or similar device in or on the same body part without cutting or puncturing the skin or a mucous membrane — All CHANGE procedures are coded using the approach EXTERNAL
Stopping, or attempting to stop, postprocedural or other acute bleeding
Putting in or on biological or synthetic material to form a new body part that to the extent possible replicates the anatomic structure or function of an absent body part — Used for gender reassignment surgery and corrective procedures in individuals with congenital anomalies
Cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part — All or a portion of the body part is separated into two or more portions
Taking or letting out fluids and/or gases from a body part — The qualifier DIAGNOSTIC is used to identify drainage procedures that are biopsies
Cutting out or off, without replacement, a portion of a body part — The qualifier DIAGNOSTIC is used to identify excision procedures that are biopsies
Taking or cutting out solid matter from a body part — The solid matter may be an abnormal byproduct of a biological function or a foreign body; it may be imbedded in a body part or in the lumen of a tubular body part. The solid matter may or may not have been previously broken into pieces
Breaking solid matter in a body part into pieces — Physical force (e.g., manual, ultrasonic) applied directly or indirectly is used to break the solid matter into pieces. The solid matter may be an abnormal byproduct of a biological function or a foreign body. The pieces of solid matter are not taken out
Putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part
Visually and/or manually exploring a body part — Visual exploration may be performed with or without optical instrumentation. Manual exploration may be performed directly or through intervening body layers
Putting back in or on all or a portion of a separated body part to its normal location or other suitable location — Vascular circulation and nervous pathways may or may not be reestablished
Taking out or off a device from a body part — If a device is taken out and a similar device put in without cutting or puncturing the skin or mucous membrane, the procedure is coded to the root operation CHANGE. Otherwise, the procedure for taking out a device is coded to the root operation REMOVAL
Restoring, to the extent possible, a body part to its normal anatomic structure and function — Used only when the method to accomplish the repair is not one of the other root operations
Correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device — Revision can include correcting a malfunctioning or displaced device by taking out or putting in components of the device such as a screw or pin
Putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part — The biological material is non-living, or is living and from the same individual. The body part may have been previously replaced, and the Supplement procedure is performed to physically reinforce and/or augment the function of the replaced body part
Putting in or on all or a portion of a living body part taken from another individual or animal to physically take the place and/or function of all or a portion of a similar body part — The native body part may or may not be taken out, and the transplanted body part may take over all or a portion of its function
