ICD-10 Code A60.9 – Anogenital herpesviral infection, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A60.9 – Anogenital herpesviral infection, unspecified
What it is
A60.9 identifies an anogenital herpesviral infection when the site is anogenital but the record does not specify the exact location or episode details. Use it for herpes simplex infection involving the genital or anal area when documentation is nonspecific.
Clinical signs
Typical findings include painful grouped vesicles, ulcers, itching, burning, or dysuria in the anogenital region. Clinical features vary; refer to documentation when the note does not clearly confirm herpes involvement.
When to use this code
Use A60.9 when the provider documents an anogenital herpes infection without naming a more specific anatomic site or subtype. It also fits when the chart confirms herpes simplex in the genital or anal area but lacks enough detail for a more precise code. Check documentation for recurrence or other qualifiers.
Do not use for
Do not use this code for oral herpes, herpes zoster, or non-herpetic genital lesions. If the record identifies a more specific anogenital herpes code, code that instead.
Coding tip
Look for the exact site and whether the note states primary, recurrent, or unspecified infection before assigning A60.9.
