ICD-10 Code A58 – Granuloma inguinale (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A58 – Granuloma inguinale
What it is
A58 identifies granuloma inguinale, also called donovanosis. It is a sexually transmitted infection that causes chronic ulcerative lesions of the genital or perineal area.
Clinical signs
Typical findings include slowly progressive, painless ulcers with a beefy-red appearance and easy bleeding. Clinical features vary; refer to documentation.
When to use this code
Use A58 when the provider documents granuloma inguinale or donovanosis as the confirmed diagnosis. It may also apply when the record clearly describes the characteristic genital ulcer disease and the clinician links it to this infection.
If the note only mentions a genital ulcer without a specific diagnosis, check documentation before coding. You should not infer A58 from nonspecific symptoms alone.
Do not use for
Do not use A58 for other sexually transmitted infections, nonspecific genital ulcers, or skin ulcers without documentation of granuloma inguinale. Check documentation if the diagnosis is uncertain.
Coding tip
Code A58 only when the provider names granuloma inguinale or donovanosis; otherwise, query for clarification.
