Non-prs chronic ulcer of r up arm with unspecified severity

This code signifies a persistent, non-healing open sore on the right upper arm that is not caused by pressure. It indicates a chronic wound that has failed to progress through the normal stages of healing, often due to underlying systemic conditions or local factors.

Apply this code for patients presenting with a long-standing ulcer on the right upper arm where pressure is explicitly ruled out as the etiology. Documentation should clearly state "chronic ulcer," specify the "right upper arm" as the location, and confirm it is "non-pressure" related.

• Always seek documentation specifying the laterality (right vs. left) and the specific anatomical site (upper arm).
• Avoid using this code if the ulcer is due to pressure; instead, refer to the appropriate pressure ulcer codes.
• If the severity is documented (e.g., stage 1, stage 2), a more specific code within the L98.A1- series should be selected.
