Other acne

This code signifies various forms of acne that do not fit into more specific categories like acne vulgaris, acne conglobata, or acne fulminans. It encompasses acneiform eruptions caused by external factors, such as contact with oils or chemicals, or those with atypical presentations not otherwise classified.

Use this code for documented cases of acne that are explicitly described as "other acne," "acne NOS," or acne due to external agents like "oil acne" or "chloracne." Documentation should clearly indicate an acneiform eruption that doesn't align with more specific ICD-9 acne codes.

• Avoid using this code if a more specific acne diagnosis (e.g., acne vulgaris, cystic acne) is documented.
• Ensure documentation specifies the type of "other acne" if possible (e.g., occupational acne, cosmetic acne) to support this less specific code.
• Consider sequencing this code after any underlying systemic conditions if the acne is a manifestation of another disease.
