Non-prs chronic ulcer of unsp thigh w necrosis of muscle

This code signifies a persistent, non-pressure-related ulcer located on an unspecified thigh, characterized by the presence of necrotic muscle tissue. This indicates a deep tissue injury extending beyond the skin and subcutaneous layers, involving muscle death.

Apply this code when documentation clearly states a chronic, non-pressure ulcer on the thigh with confirmed muscle necrosis. This is appropriate for ulcers resulting from conditions like peripheral vascular disease, diabetes, or trauma, where pressure is not the primary etiology.

• Ensure documentation specifies "non-pressure" and "necrosis of muscle" to support this code.
• Do not use for pressure ulcers; refer to the L89 series for those.
• Laterality (left/right) is unspecified for this code; if known, a more specific code should be sought.
