ICD-10 Code H02.844 – Edema of left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.844 – Edema of left upper eyelid
What it is
H02.844 identifies swelling of the left upper eyelid. Use it when documentation specifies edema limited to that eyelid, without a broader eye or facial diagnosis.
Clinical signs
Typical findings include visible puffiness, fullness, or enlargement of the left upper lid. Clinical features vary; refer to documentation for the exact cause and whether redness, pain, or irritation is present.
When to use this code
Use this code when the provider documents edema of the left upper eyelid as the condition being treated or assessed. It is appropriate for localized eyelid swelling from an unspecified cause when no more specific diagnosis is recorded.
If the note identifies a different eyelid, bilateral swelling, or a more specific disorder, code that condition instead. Check documentation when the swelling is part of a broader ocular or facial problem.
Do not use for
Do not use H02.844 for swelling of the lower eyelid, both eyelids, or generalized facial edema. Do not use it when the record supports a more specific eyelid disorder.
Coding tip
Code only the side and eyelid documented; laterality matters here.
