Non-prs chr ulc of left thigh with msl invl w/o evd of necr

This code signifies a persistent open sore on the left thigh that is not caused by pressure and extends into the muscle tissue. There is no indication of dead tissue (necrosis) present within the ulcer. This condition often arises from underlying vascular insufficiency or neuropathic factors.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer located specifically on the left thigh, with the depth of tissue loss reaching the muscle layer. Supporting documentation should explicitly state the absence of necrosis. This code is appropriate for ulcers stemming from conditions like venous stasis or diabetic neuropathy.

• Ensure documentation specifies "left thigh" and "muscle involvement" to differentiate from other anatomical sites or tissue depths.
• Verify the absence of necrosis; if present, a different subcategory code would be required.
• Always sequence an underlying cause (e.g., chronic venous insufficiency, diabetes mellitus with complications) before this ulcer code.
