When to Use

Use a code from this group when an implanted or external device on a lower muscle is removed and replaced with the same type of device without cutting or puncturing the skin or mucous membrane. These codes apply in inpatient settings where documentation shows both removal and replacement of the device during the same encounter.

ICD-10-PCS Codes

ICD-10-PCS Code	Description
0K2YX0Z	Change Drainage Device in Lower Muscle, External Approach
0K2YXYZ	Change Other Device in Lower Muscle, External Approach

Typical Clinical Scenarios

An elderly patient with a longstanding external muscle stimulator pad used for lower leg spasticity presents to the inpatient unit because the adhesive housing failed and the device no longer secures to the gastrocnemius muscle despite intact skin. The device is removed at bedside and an identical external stimulation pad is reapplied to the same lower muscle without incision or puncture. Typical codes: 0K2YX0Z
A middle-aged patient admitted electively for optimization of a transcutaneous drainage catheter interface used over a lower thigh muscle after chronic seroma formation; the external drainage port is exchanged for the same type of drainage device without breaching the skin. The planned change is performed in the inpatient setting to ensure secure placement and monitor output. Typical codes: 0K2YX0Z
A postoperative patient develops malfunction of an external neuromuscular surface device placed on the calf muscle during prior inpatient care; because the device is failing but the skin barrier remains intact, clinicians remove the defective unit and immediately replace it with a similar external device to restore therapy without surgical entry. Typical codes: 0K2YX0Z, 0K2YXYZ
