ICD-10 Code B35.0 – Tinea barbae and tinea capitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B35.0 – Tinea barbae and tinea capitis
What it is
B35.0 identifies a dermatophyte fungal infection of the scalp or beard area. Use it for ringworm affecting hair-bearing skin in these locations.
Clinical signs
Typical findings include scaly patches, broken hairs, hair loss, or inflamed lesions in the scalp or beard region. Clinical features vary; refer to documentation.
When to use this code
Use B35.0 when the provider documents tinea capitis, tinea barbae, or both. It also fits confirmed dermatophyte infection limited to the scalp or beard area. If the site is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for fungal infections outside the scalp or beard, or for nonspecific dermatitis without documentation of tinea. Check documentation if the record does not confirm a dermatophyte infection.
Coding tip
Code B35.0 only when the affected anatomic site and fungal diagnosis are both documented.
