Chronic ulcer of unspecified site

This code signifies a persistent open sore on the skin or mucous membrane that has failed to heal over an extended period. It indicates the presence of an ulcer where the specific anatomical location is not documented or is unknown.

Use this code when documentation clearly states "chronic ulcer" but provides no further detail regarding the affected body site. This is appropriate when the physician's notes lack specificity regarding the ulcer's location, or when the ulcer's site is truly undetermined.

• Avoid using this code if any specific anatomical site (e.g., leg, foot, sacrum) is documented; instead, code to the specific site.
• Query the provider for clarification on the ulcer's location whenever possible to allow for more specific coding.
• This code should be used as a last resort when no other more specific chronic ulcer code can be assigned.
