Diseases of lips

This code encompasses a range of non-specific inflammatory or other pathological conditions affecting the lips, excluding those with a more precise etiology or congenital origin. It describes various acquired lip disorders that are not classified elsewhere.

Use this code for documented conditions such as cheilitis NOS, lip fissures, or other unspecified diseases of the lips when a more specific diagnosis is not provided or cannot be determined. This code is appropriate when the physician's documentation indicates a lip disorder without further detail regarding its cause or specific type.

• Carefully review documentation to ensure no more specific code for lip disorders (e.g., specific types of cheilitis, infectious causes) is applicable.
• Pay close attention to the "Excludes1" notes to avoid co-coding conditions that are mutually exclusive, such as cheilitis due to radiation or candidiasis.
• If a definitive cause for the lip condition is identified (e.g., nutritional deficiency, specific infection), code that specific condition instead.
