ICD-10-PCS Code For Left Lower Arm And Wrist Muscle: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 0K8B includes procedures performed to divide muscles in the lower arm and wrist on the left side. These ICD-10-PCS codes are used for inpatient documentation when a surgeon separates or transects muscle tissue of the left lower arm or wrist without draining fluids or gases. Accurate coding within the ICD-10-PCS 0K8B group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

When to Use

Use a code from this group when the operative record documents division of left lower arm or wrist muscle tissue without any concurrent drainage of fluids or gases. These codes apply for inpatient procedures where the primary intent is to divide muscle tissue rather than to excise, repair, or otherwise manipulate other tissue types.

Typical Clinical Scenarios

An adult patient presents after a crush injury to the left forearm with increasing compartmental pressure and focal entrapment of a tight flexor muscle bundle causing ischemic pain and limiting finger movement. In the inpatient operating room the surgeon performs an open division of the affected left lower arm/wrist muscle tissue to release the constriction and restore perfusion and function. This is done without draining fluids or gases, with open visualization of the muscle. Typical codes: 0K8B0ZZ
A middle-aged patient with chronic volar forearm tendon adhesions and a contracted forearm flexor muscle limiting wrist and finger extension is scheduled electively for release. In the inpatient setting the surgeon performs a percutaneous division of the specific left lower arm/wrist muscle fibers to lengthen and reduce contracture under controlled conditions without drainage. Typical codes: 0K8B3ZZ
A patient with prior left forearm surgery develops recurrent scarring and painful muscle tethering around the wrist causing functional impairment and recurrent nerve irritation. To address the complication, the surgeon performs a percutaneous endoscopic division of the scarred left lower arm/wrist muscle tissue to free the muscle and relieve symptoms, using an endoscopic approach without fluid or gas drainage. Typical codes: 0K8B4ZZ
