ICD-10 Code H00.13 – Chalazion right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.13 – Chalazion right eye, unspecified eyelid
What it is
This code identifies a chalazion on the right eye when the affected eyelid is not specified. A chalazion is a localized, usually painless eyelid lump caused by blockage of a meibomian gland.
Clinical signs
Typical findings include a firm, round eyelid nodule, mild swelling, and possible tenderness if inflamed. Clinical features vary; refer to documentation.
When to use this code
Use H00.13 when the provider documents a chalazion of the right eye but does not identify the upper or lower eyelid. It also fits when the record clearly states a chalazion and laterality, yet eyelid location remains unspecified. Check documentation if the note is ambiguous.
Do not use for
Do not use this code for stye, blepharitis, or other eyelid infections. If the chart specifies a different eyelid or a different lesion, code that documented condition instead.
Coding tip
Verify laterality and eyelid site in the note before assigning H00.13.
