ICD-10 Code B87.2 – Ocular Myiasis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B87.2 – Ocular myiasis
What it is
Use this code for infestation of the eye or surrounding tissues by fly larvae. It identifies a parasitic condition affecting the ocular area, not a general eye infection.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include eye irritation, redness, pain, tearing, foreign-body sensation, visible larvae, or eyelid involvement.
When to use this code
Use B87.2 when the record clearly states ocular myiasis or fly larval infestation of the eye. It may apply when the provider documents larvae in the conjunctiva, eyelid, or other ocular structures. If the note only describes nonspecific eye inflammation, check documentation.
Do not use for
Do not use this code for other parasitic infections without eye involvement, or for routine conjunctivitis, blepharitis, or foreign-body sensation alone. Check documentation if the organism or site is unclear.
Coding tip
Assign B87.2 only when the provider documents ocular myiasis or equivalent wording; do not infer it from eye symptoms alone.
