ICD-10 Code H00.19 – Chalazion unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.19 – Chalazion unspecified eye, unspecified eyelid
What it is
H00.19 identifies a chalazion when the eye and eyelid are not further specified. It is a localized, usually painless eyelid lump caused by blockage and inflammation of a meibomian gland.
Clinical signs
Typical findings include a firm eyelid nodule, mild swelling, and localized tenderness or irritation. Clinical features vary; refer to documentation if the record does not clearly describe the affected eye or eyelid.
When to use this code
Use H00.19 when the provider documents chalazion but does not specify the eye or eyelid involved. It also fits when the note states “unspecified eye” or “unspecified eyelid” without laterality or exact location. If the chart identifies a more specific site, code that instead.
Do not use for
Do not use this code for stye, eyelid cellulitis, or other inflammatory eyelid disorders. If documentation gives a specific eye, eyelid, or laterality, choose the more precise code.
Coding tip
Check the ophthalmology note carefully for laterality and exact eyelid location before defaulting to H00.19.
