Non-pressure chronic ulcer of buttock with unsp severity

This code signifies a persistent, open sore on the buttock that is not caused by pressure. These ulcers are typically slow-healing and can be associated with underlying conditions like venous insufficiency, arterial disease, or neuropathy, but the specific severity is not documented.

Apply this code when documentation clearly indicates a chronic, non-pressure ulcer located on the buttock, and the physician has not specified the severity (e.g., stage). This code is appropriate when the ulcer's etiology is not pressure-related, such as those due to vascular compromise or diabetic neuropathy.

• Always seek documentation for the specific severity (e.g., stage 1, 2, 3, 4, unstageable) to use a more specific code if available.
• Distinguish carefully between pressure ulcers (L89.-) and non-pressure ulcers; the location is key for this code.
• Code any underlying systemic conditions (e.g., diabetes mellitus, peripheral vascular disease) as additional diagnoses.
