ICD-10 Code H00.031 – Abscess of right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.031 – Abscess of right upper eyelid
What it is
This code identifies a localized pus-filled infection in the right upper eyelid. It is used when the record specifically documents an abscess in that eyelid.
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 H00.031 when the provider documents an abscess limited to the right upper eyelid. It fits outpatient, emergency, or specialist notes describing a localized eyelid infection. If the chart only says “eyelid infection” or “swelling,” check documentation before coding.
Do not use for
Do not use this code for stye, chalazion, or abscesses in another eyelid location. If the laterality or exact site is unclear, check documentation.
Coding tip
Confirm both laterality and eyelid location before assigning the code.
