ICD-10 Code H02.842 – Edema of right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.842 – Edema of right lower eyelid
What it is
H02.842 identifies swelling of the right lower eyelid. Use it when the record documents edema limited to that eyelid, without a more specific underlying diagnosis.
Clinical signs
Typical findings include visible puffiness, fullness, or fluid-related enlargement of the right lower lid. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents edema specifically affecting the right lower eyelid. It is appropriate when the note does not identify a more specific cause, such as trauma, infection, or allergy. If the cause is documented, code the condition as directed by the record.
Do not use for
Do not use it for swelling of the upper eyelid, the left eye, or both eyelids. Check documentation if the edema is part of a broader facial, orbital, or systemic condition.
Coding tip
Confirm laterality and eyelid location in the chart before assigning H02.842.
