Non-prs chr ulcer of chest with bone invl w/o evd of necr

This code signifies a persistent, non-pressure-related ulcer located on the chest wall that has progressed to involve the underlying bone. Importantly, there is no necrotic tissue present within the ulcer bed. This condition typically arises from causes other than sustained pressure, such as trauma, infection, or vascular insufficiency.

Apply this code when documentation clearly indicates a chronic ulcer on the chest, explicitly stating bone involvement without any mention of necrosis. This code is appropriate for ulcers not caused by pressure, such as those resulting from surgical dehiscence, radiation, or chronic infection. Physician notes must specify the chronicity and the absence of necrotic tissue.

• Ensure the documentation explicitly states "non-pressure" and "bone involvement" for the chest ulcer.
• Differentiate from pressure ulcers (L89.-) and ulcers with necrosis (L98.49-).
• Always sequence this code after any underlying systemic condition contributing to the ulcer formation.
