Non-prs chr ulc of l forearm with bone invl w/o evd of necr

This code signifies a persistent, non-pressure-related open sore on the left forearm that has progressed to affect the underlying bone structure. Crucially, there is no evidence of tissue death (necrosis) within the ulcer or surrounding area.

Apply this code when documentation clearly indicates a chronic ulcer on the left forearm, explicitly stating bone involvement without necrosis. This typically occurs in patients with conditions like peripheral vascular disease, diabetes, or autoimmune disorders, where the ulcer has eroded through soft tissue to reach bone.

• Ensure documentation specifies "chronic" and "non-pressure" to differentiate from acute or pressure ulcers.
• Verify laterality (left forearm) and the presence of bone involvement, as well as the absence of necrosis.
• Always code any underlying systemic condition (e.g., diabetes mellitus with complications) as a primary diagnosis when applicable.
