Non-pressure chronic ulcer of l up arm with oth severity

This code signifies a persistent, non-pressure-related open sore on the patient's left upper arm that has a specified severity beyond a simple superficial ulcer. It indicates tissue loss extending at least into the dermis, but not necessarily involving muscle or bone, and is not caused by sustained pressure.

Apply this code when documentation clearly identifies a chronic ulcer on the left upper arm that is not a pressure ulcer and the severity is described as something other than unspecified, such as a stage 2, 3, or 4 ulcer, or an ulcer with necrosis. Supporting documentation should include the location, chronicity, etiology (non-pressure), and a specific description of the ulcer's depth or tissue involvement.

• Ensure the documentation explicitly states "non-pressure" to differentiate from pressure ulcers (L89.-).
• Verify the laterality is specifically the "left upper arm"; other locations have different codes.
• Confirm the severity is "other specified" and not simply "unspecified" (L98.A119 for unspecified severity).
