ICD-10 Code B08.1 – Molluscum contagiosum (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B08.1 – Molluscum contagiosum
What it is
B08.1 identifies molluscum contagiosum, a contagious viral skin infection that causes small, raised bumps. Use it when the diagnosis is documented and the lesions are attributed to molluscum contagiosum.
Clinical signs
Typical findings include firm, dome-shaped papules with a central dimple or umbilication. Clinical features vary; refer to documentation if the appearance is atypical or the diagnosis is uncertain.
When to use this code
Use B08.1 when the provider documents molluscum contagiosum as the reason for the visit or as an active diagnosis. It also fits follow-up care for known lesions, including evaluation of spread or persistence. Code only when the condition is confirmed in the record.
Do not use for
Do not use B08.1 for nonspecific viral rash, warts, or other skin growths without documentation of molluscum contagiosum. Check documentation if the lesion type is not clearly identified.
Coding tip
Code B08.1 only when the chart names molluscum contagiosum; otherwise, query for a more specific diagnosis.
