ICD-10 Code B60.1 – Acanthamebiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B60.1 – Acanthamebiasis
What it is
Acanthamebiasis is an infection caused by Acanthamoeba, a free-living amoeba. It most often affects the eye, skin, or central nervous system, and the code identifies the confirmed diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Eye involvement may include pain, redness, tearing, photophobia, and blurred vision, while skin or brain infection presents with site-specific findings.
When to use this code
Use B60.1 when the record clearly documents acanthamebiasis or Acanthamoeba infection. Apply it for confirmed disease, not just exposure, suspected infection, or nonspecific keratitis without organism identification. If the site is documented, you may still code the infection when supported by the note.
Do not use for
Do not use this code for other amoebic infections, contact lens irritation, or keratitis without Acanthamoeba documented. Check documentation if the organism or diagnosis is uncertain.
Coding tip
Code B60.1 only when the provider names Acanthamoeba or acanthamebiasis in the assessment.
