Acne varioliformis

This code represents a rare, chronic inflammatory skin condition characterized by recurrent crops of umbilicated papules and vesicles, primarily affecting the forehead and temples. These lesions heal with varioliform (pock-like) scarring, resembling those left by smallpox.

Use this code for patients diagnosed with acne varioliformis, also known as acne necrotica miliaris or folliculitis varioliformis. Documentation should clearly describe the characteristic recurrent papulovesicular lesions, their distribution, and the resulting varioliform scarring.

• Differentiate from common acne vulgaris (706.1) which lacks the characteristic scarring and specific lesion morphology.
• Ensure documentation specifies "varioliformis" or "necrotica miliaris" to support this specific diagnosis.
• Consider additional codes for any associated complications or treatments, if applicable.
