ICD-10 Code H00.033 – Abscess of Eyelid Right Eye, Unspecified Eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.033 – Abscess of eyelid right eye, unspecified eyelid
What it is
This code identifies a localized abscess in the right eyelid when the specific upper or lower eyelid is not documented. Use it for a pus-filled eyelid infection on the right side.
Clinical signs
Typical findings include eyelid swelling, redness, tenderness, and a focal area of fluctuance or drainage. Clinical features vary; refer to documentation.
When to use this code
Use H00.033 when the provider documents a right eyelid abscess but does not specify whether it involves the upper or lower lid. It also fits notes describing a right eyelid abscess, eyelid furuncle, or localized purulent infection if coded as an abscess. Confirm laterality and eyelid specificity in the record.
Do not use for
Do not use this code for chalazion, hordeolum, or generalized periorbital cellulitis unless an abscess is specifically documented. Check documentation if the infection site is not clearly the right eyelid.
Coding tip
Assign the more specific eyelid code whenever upper or lower lid is documented; use H00.033 only when the eyelid location remains unspecified.
