Medical & Surgical Section/Root Operations
The medical and surgical procedure section contains 31 root operations, which are arranged in groups with similar attributes. The root operations are:
Alteration Modifying the anatomic structure of a body part without affecting the function of the body part
Principal purpose is to improve appearance
Bypass 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
Change 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
All Change procedures are coded using the approach External
Control Stopping, or attempting to stop, postprocedural bleeding
The site of the bleeding is coded as an anatomical region and not to a specific body part
Creation Making a new genital structure that does not take over the function of a body part
Used only for sex change operations
Destruction 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
Detachment Cutting off all or part of the upper or lower extremities
The body part value is the site of the detachment, with a qualifier if applicable to further specify the level where the extremity was detached
Dilation Expanding an orifice or the lumen of a tubular body part
The orifice can be a natural orifice or an artificially created orifice. Accomplished by stretching a tubular body part using intraluminal pressure or by cutting part of the orifice or wall of the tubular body part
Division 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
Drainage Taking or letting out fluids and/or gases from a body part
The qualifier Diagnostic is used to identify drainage procedures that are biopsies
Excision Cutting out or off, without replacement, a portion of a body part
The qualifier Diagnostic is used to identify excision procedures that are biopsies
Extirpation 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
Extraction 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 extractions that are biopsies
Fragmentation 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
Fusion Joining together portions of an articular body part rendering the articular body part immobile
The body part is joined together by fixation device, bone graft, or other means
Insertion Putting in a non-biological appliance that monitors, assists, performs or prevents a physiological function but does not physically take the place of a body part
Inspection 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
Map Locating the route of passage of electrical impulses and/or locating functional areas in a body part
Applicable only to the cardiac conduction mechanism and the central nervous system
Occlusion Completely closing an orifice or the lumen of a tubular body part
The orifice can be a natural orifice or an artificially created orifice
Reattachment 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
Release Freeing a body part from an abnormal physical constraint by cutting or by use of force
Some of the restraining tissue may be taken out but none of the body part is taken out
Removal 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 the device is coded to the root operation
Repair 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
Replacement 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
Reposition 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
Resection Cutting out or off, without replacement, all of a body part
Restriction Partially closing an orifice or the lumen of a tubular body part
The orifice can be a natural orifice or an artificially created orifice
Revision 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
Supplement Putting in or on biological or synthetic material that physically reinforces and/or augments the function 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
Transfer 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
Transplantation 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
Character #4 Body Parts
The body part is specified in the fourth character. The body part indicates the specific part of the body system on which the procedure was performed (e.g., duodenum). Tubular body parts are defined in ICD-10-PCS as those hollow body parts that provide a route of passage for solids, liquids, or gases. They include the cardiovascular system, and body parts such as those contained in the gastrointestinal tract, genitourinary tract, biliary tract, and respiratory tract.
