ICD-10 Code H00.14 – Chalazion left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.14 – Chalazion left upper eyelid
What it is
H00.14 identifies a chalazion on the left upper eyelid. It is a localized, usually noninfectious blockage of an eyelid oil gland that causes a firm lump.
Clinical signs
Typical findings include a painless or mildly tender eyelid nodule, swelling, and localized redness. Clinical features vary; refer to documentation when the note does not clearly describe the left upper eyelid.
When to use this code
Use this code when the provider documents a chalazion specifically on the left upper eyelid. It fits encounters for evaluation, follow-up, or persistent lesions when the diagnosis is confirmed. If laterality or eyelid location is unclear, check documentation before coding.
Do not use for
Do not use H00.14 for styes, generalized eyelid inflammation, or chalazia on a different eyelid. If the record only says “eyelid lump” or “mass,” check documentation.
Coding tip
Confirm both laterality and upper eyelid location in the note before assigning H00.14.
