Non-prs chr ulcer of l forearm with msl invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on the left forearm that extends into the muscle tissue. It specifically indicates that there is no dead tissue (necrosis) present within the ulcer. This type of ulcer often results from underlying systemic conditions, trauma, or vascular insufficiency.

Use this code when documentation clearly states a chronic, non-pressure ulcer located on the left forearm. The ulcer must be documented as extending to or involving the muscle layer, and the absence of necrosis must be explicitly noted. This code is appropriate for ulcers that have been present for an extended period and are not healing spontaneously.

• Differentiate from pressure ulcers (L89.-) and acute ulcers; this code is for non-pressure and chronic.
• Ensure documentation specifies "left forearm" and "muscle involvement without evidence of necrosis" to avoid miscoding.
• Always sequence this code after the underlying cause of the ulcer, if known (e.g., diabetes, venous insufficiency).
