Two Important ICD-10 Guideline Changes for FY 2022 – October 2021 Coding Tip

Guideline Changes:

B3.7 Control vs. More Specific Root Operations

  • The root operation control is defined as, “Stopping, or attempting to stop, postprocedural or other acute bleeding.” Control is the root operation coded when the procedure performed to achieve hemostasis, beyond what would be considered integral to a procedure, utilizes techniques (e.g. cautery, application of substances or pressure, suturing or ligation or clipping of bleeding points at the site) that are not described by a more specific root operation definition, such as Bypass, Detachment, Excision, Extraction, Reposition, Replacement, or Resection. If a more specific root operation definition applies to the procedure performed, then the more specific root operation is coded instead of Control.


  • If a procedure is performed on a continuous section of a tubular body part, code the body part value corresponding to the anatomically most proximal (closest to the heart) portion of the tubular body part. Example: A procedure performed on a continuous section of artery from the femoral artery to the external iliac artery with the point of entry at the femoral artery is coded to the external iliac body part.
