ICD-10 Code H02.849 – Edema of unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.849 – Edema of unspecified eye, unspecified eyelid
What it is
This code identifies swelling of the eyelid and/or eye area when the provider does not specify the exact eye or eyelid involved. Use it for nonspecific edema documented in the periocular region.
Clinical signs
Typical findings include visible puffiness, fullness, or tissue swelling around the eye or eyelid. Clinical features vary; refer to documentation.
When to use this code
Use H02.849 when the record documents edema of an eye or eyelid but does not identify a side or a more specific eyelid condition. It is appropriate when the note only states “eye swelling” or “eyelid edema.” If laterality or a more precise diagnosis is documented, code that instead.
Do not use for
Do not use this code when the swelling is clearly localized to a specific eyelid, eye, or another diagnosed disorder with a more exact code. Check documentation if the edema is part of a broader condition.
Coding tip
Query for laterality and specificity before assigning H02.849.
