K The Muscles body system is identified by the character “K” 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.
Section:
0 = Medical and Surgical

Muscles
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
Physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent — None of the body part is physically taken out
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
Pulling or stripping out or off all or a portion of a body part by the use of force — The qualifier DIAGNOSTIC is used to identify extraction procedures that are biopsies
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
Freeing a body part from an abnormal physical constraint by cutting or by the use of force — Some of the restraining tissue may be taken out but none of the body part is taken out
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
Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part — The body part may have been taken out or replaced, or may be taken out, physically eradicated, or rendered nonfunctional during the Replacement procedure. A Removal procedure is coded for taking out the device used in a previous replacement procedure
Moving to its normal location, or other suitable location, all or a portion of a body part — The body part is moved to a new location from an abnormal location, or from a normal location where it is not functioning correctly. The body part may or may not be cut out or off to be moved to the new location
Cutting out or off, without replacement, all of a body part
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
Moving, without taking out, all or a portion of a body part to another location to take over the function of all or a portion of a body part — The body part transferred remains connected to its vascular and nervous supply
