ICD-10 Code H00.039 – Abscess of eyelid unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H00.039 – Abscess of eyelid unspecified eye, unspecified eyelid
What it is
This code identifies a localized collection of pus in an eyelid, with no eye laterality or eyelid location specified. Use it when the record states an eyelid abscess but does not name the right or left eye.
Clinical signs
Typical findings include eyelid swelling, redness, tenderness, and a focal painful lump that may drain. Clinical features vary; refer to documentation if the note does not clearly describe an abscess.
When to use this code
Use H00.039 when the provider documents an eyelid abscess and the chart does not specify which eye is affected. It also fits when laterality is unavailable or not recorded, but the diagnosis is clearly an abscess rather than a stye or cellulitis.
Do not use for
Do not use this code for a chalazion, hordeolum, or diffuse eyelid cellulitis unless the record specifically supports an abscess. Check documentation if the lesion type or eye laterality is unclear.
Coding tip
Query for laterality whenever possible, because unspecified codes should be used only when the record truly lacks that detail.
