About the 0J Body System
The ICD-10-PCS codes for the Subcutaneous Tissue and Fascia focus on a variety of Medical and Surgical root operations addressing this specific body region. These operations involve modifying, removing, or repairing different aspects of the subcutaneous tissues and fascia.
For example, Alteration (0J0) refers to modifying the structure without affecting function, while Insertion (0JH) involves placing a non-biological device that supports physiological functions. Procedures like Excision (0JB) remove a portion of tissue, whereas Destruction (0J5) eradicates parts using energy or force. Other operations include Drainage (0J9) to remove fluids, Repair (0JQ) to restore normal anatomy and function, and Replacement (0JR) inserting material that takes the place of tissue. These codes provide precise documentation for surgical or diagnostic interventions involving the subcutaneous tissue and fascia, facilitating accurate clinical communication and billing.
Questions About This Page
How many codes are in the 0J body system?
The 0J body system contains 2,906 ICD-10-PCS codes in FY 2026, organized into 17 root operations. 2,872 of them are billable on inpatient claims.
What is a root operation?
The root operation is the third character of every ICD-10-PCS code and names the objective of the procedure. Drainage takes fluid out, Excision cuts out a portion of a body part, and Resection removes all of one. Picking the right root operation is the central skill of PCS coding, so each one above carries its official CMS definition.
