ICD-10 Code H02.31 – Blepharochalasis right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.31 – Blepharochalasis right upper eyelid
What it is
Use H02.31 for blepharochalasis affecting the right upper eyelid. This describes recurrent eyelid swelling that can lead to lax, thinned skin and drooping over time.
Clinical signs
Typical findings include intermittent painless edema of the upper eyelid, often with progressive redundancy or ptosis. Clinical features vary; refer to documentation.
When to use this code
Assign this code when the provider documents blepharochalasis specifically on the right upper eyelid. Use it for encounters focused on the chronic eyelid change, not just a brief episode of eyelid swelling.
If the note describes both eyelids or a different eyelid location, choose the more specific documented code. Check documentation when laterality or eyelid site is unclear.
Do not use for
Do not use H02.31 for nonspecific eyelid edema, allergic swelling, or infection without blepharochalasis. Do not code it when the right upper eyelid is not documented.
Coding tip
Confirm laterality and eyelid site in the assessment, because blepharochalasis codes are location-specific.
