Non-prs chronic ulc unsp prt of r low leg w necros muscle

This code signifies a persistent, open sore on an unspecified area of the right lower leg, not caused by pressure, that has progressed to involve the muscle tissue. The ulceration is characterized by the presence of necrotic (dead) muscle tissue within its base or margins. This indicates a severe and deep tissue injury.

Apply this code when documentation specifies a chronic, non-pressure ulcer on the right lower leg with confirmed muscle necrosis, but the exact anatomical location on the lower leg is not specified. Supporting documentation should clearly state "chronic ulcer," "non-pressure related," "right lower leg," and "necrosis of muscle."

• Ensure the documentation explicitly states "necrosis of muscle" to differentiate from necrosis of fat or bone.
• Avoid using this code if a more specific anatomical site on the right lower leg (e.g., ankle, calf) is documented; instead, use the appropriate site-specific code.
• Always sequence this code after any underlying systemic conditions contributing to the ulcer (e.g., diabetes mellitus with complications).
