ICD-10 Code H02.843 – Edema of right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.843 – Edema of right eye, unspecified eyelid
What it is
H02.843 identifies swelling of the right eyelid without a more specific eyelid diagnosis. Use it when the record documents edema of the right eye area and does not name a cause or other eyelid condition.
Clinical signs
Typical findings include visible puffiness, eyelid fullness, or localized swelling on the right side. Clinical features vary; refer to documentation for associated redness, tenderness, or other eye findings.
When to use this code
Use this code when the provider documents right eyelid edema, swelling, or puffiness and does not specify a more precise disorder. It may fit isolated eyelid swelling in outpatient, emergency, or follow-up notes. If the cause is identified, code the documented condition instead.
Do not use for
Do not use it for generalized facial edema, orbital swelling, or bilateral eyelid edema unless the record clearly supports right-sided involvement. Check documentation if the note describes infection, trauma, allergy, or another specific eyelid diagnosis.
Coding tip
Code the laterality exactly as documented, and query if the note says only “eyelid swelling” without specifying the right eye.
