ICD-10 Code L70.0 – Acne vulgaris (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L70.0 – Acne vulgaris
What it is
L70.0 identifies acne vulgaris, a common inflammatory skin condition involving clogged pores, comedones, papules, pustules, or nodules. Use it when the record documents ordinary acne rather than another acneiform disorder.
Clinical signs
Typical findings include blackheads, whiteheads, inflamed bumps, and sometimes deeper tender lesions on the face, chest, or back. Clinical features vary; refer to documentation.
When to use this code
Use L70.0 when the clinician clearly documents acne vulgaris, acne, or comedonal/inflammatory acne consistent with this diagnosis. It is appropriate for routine outpatient visits, follow-up care, or evaluation of acne-related skin lesions. Check documentation if the note suggests another acne type or a medication-related eruption.
Do not use for
Do not use this code for acne rosacea, hidradenitis suppurativa, or drug-induced acneiform eruptions. If the chart does not specify acne vulgaris, check documentation.
Coding tip
Code the documented acne type exactly, and avoid L70.0 when the provider names a different acne disorder.
