Non-prs chronic ulcer of unsp forearm with unsp severity

This code signifies a persistent open sore on the forearm that is not caused by pressure. The ulcer's specific location on the forearm (e.g., anterior, posterior) and its severity (e.g., stage) are not documented or are unknown.

Apply this code when documentation indicates a chronic, non-pressure ulcer on the forearm, but lacks further specificity regarding the exact anatomical site or the depth/stage of the ulcer. This is appropriate when the provider's notes simply state "chronic forearm ulcer" without additional detail.

• Avoid this code if the ulcer's severity (e.g., stage 1, with necrosis) or specific forearm location (e.g., right anterior forearm) is documented; more specific codes exist.
• Always query the provider for more detailed information on ulcer location and severity to allow for more precise coding.
• Do not use for pressure ulcers; those are coded under category L89.
