The 3rd character refers to the root operation or the objective of the procedure.

Anatomical Regions, Lower Extremities

  • 0Y0 - Alteration

    Modifying the anatomic structure of a body part without affecting the function of the body part — Principal purpose is to improve appearance

  • 0Y2 - 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

  • 0Y3 - Control

    Stopping, or attempting to stop, postprocedural or other acute bleeding — The site of the bleeding is coded as an anatomical region and not to a specific body part

  • 0Y6 - Detachment

    Cutting off all or a portion 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

  • 0Y9 - 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

  • 0YB - 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

  • 0YH - Insertion

    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

  • 0YJ - 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

  • 0YM - 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

  • 0YP - 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 a device is coded to the root operation REMOVAL

  • 0YQ - 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

  • 0YW - 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

  • 0YU - Supplement

    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
