2025 ICD-10-CM code L70

Acne.

Use additional codes to specify the type of acne (L70.0-L70.9) if documented. Do not use L70 with acne keloid (L73.0).

Medical necessity for acne treatment is based on the severity of the condition and its impact on the patient's quality of life. Treatment is considered medically necessary when acne causes physical discomfort, emotional distress, or scarring.

Diagnosis and management of acne, including assessing severity, prescribing appropriate treatments (topical or oral medications), educating patients on skincare, and considering referral to a dermatologist for severe or resistant cases.

In simple words: Acne is a common skin problem where your skin gets pimples because oil and dead skin cells clog up tiny holes in your skin.

Acne is a common skin condition characterized by the formation of pimples due to clogged hair follicles. It primarily affects areas like the face, neck, back, chest, and shoulders.

Example 1: A 15-year-old patient presents with comedonal acne on their forehead and nose., A 25-year-old patient presents with inflammatory acne, including papules and pustules, on their cheeks and chin., A 30-year-old patient presents with nodulocystic acne on their back and chest.

Type of acne (e.g., comedonal, inflammatory, nodulocystic), location and severity of lesions, associated symptoms (e.g., pain, itching), past treatments, and response to treatment.
