L98.A213
ICD-10-CMNon-pressure chronic ulcer of right forearm with necrosis of muscle
This code signifies a persistent, non-pressure-related open sore located on the right forearm, characterized by the presence of dead muscle tissue. This indicates a severe, deep ulceration extending beyond the subcutaneous tissue into the underlying muscle.
Use this code for patients presenting with a chronic ulcer on the right forearm where the etiology is not pressure-related (e.g., venous stasis, arterial insufficiency, neuropathic, traumatic). Documentation must explicitly state the ulcer's location, chronicity, non-pressure origin, and involvement of muscle necrosis.
