ICD-10 Code L70.8 – Other acne (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L70.8 – Other acne
What it is
L70.8 identifies acne that does not fit the more specific ICD-10 acne categories. Use it for documented acne variants or atypical presentations when the record supports acne but not a narrower code.
Clinical signs
Clinical features vary; refer to documentation. Acne commonly includes comedones, papules, pustules, or inflammatory lesions on the face, chest, or back, but the specific pattern may differ in this category.
When to use this code
Use L70.8 when the clinician documents “other acne,” “atypical acne,” or a named acne type not captured by a more specific code. It may also fit when the note confirms acne but does not specify a standard subtype. Check documentation if the diagnosis is unclear.
Do not use for
Do not use this code for acne vulgaris, acne conglobata, or acne fulminans when a more specific code is documented. If the condition is not acne or the record is vague, check documentation.
Coding tip
Code the most specific acne diagnosis documented; if the subtype is not stated, use L70.8 only when the record clearly supports “other acne.”
