ICD-10 Code H02.34 – Blepharochalasis left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.34 – Blepharochalasis left upper eyelid
What it is
Use this code for blepharochalasis affecting the left upper eyelid. It refers to recurrent eyelid swelling that can lead to lax, stretched skin and a drooping appearance.
Clinical signs
Typical findings include intermittent painless swelling of the upper eyelid, followed by thin, redundant skin or eyelid laxity. Clinical features vary; refer to documentation.
When to use this code
Assign H02.34 when the provider documents blepharochalasis specifically in the left upper eyelid. Use it for chronic or recurrent cases where the laterality and eyelid are clearly identified. Check documentation if the note only says eyelid edema or ptosis without this diagnosis.
Do not use for
Do not use this code for nonspecific eyelid swelling, trauma-related edema, or ptosis without blepharochalasis. If the record does not confirm the left upper eyelid, check documentation.
Coding tip
Verify both laterality and eyelid location in the provider note before coding H02.34.
