ICD-10 Code H00.03 – Abscess of eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.03 – Abscess of eyelid
What it is
H00.03 identifies a localized collection of pus in the eyelid tissue. Use it when the record documents an eyelid abscess, not a generalized eye infection.
Clinical signs
Typical findings include a tender, swollen, red eyelid with a fluctuant or draining area. Clinical features vary; refer to documentation for laterality and whether the abscess is superficial or deeper.
When to use this code
Use H00.03 when the provider documents an abscess of the eyelid as the diagnosed condition. It fits encounters for evaluation, follow-up, or drainage of a confirmed eyelid abscess. Check documentation if the note instead describes hordeolum, cellulitis, or a cyst.
Do not use for
Do not use this code for simple eyelid swelling, conjunctivitis, or infection limited to the eyeball. If the record only says “eyelid lesion” or “lump,” check documentation before assigning H00.03.
Coding tip
Confirm the provider’s exact wording and laterality, because eyelid conditions are often documented imprecisely.
