ICD-10 Code H02.439 – Paralytic ptosis unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.439 – Paralytic ptosis unspecified eyelid
What it is
Paralytic ptosis unspecified eyelid means drooping of the upper eyelid caused by weakness or paralysis of the muscles or nerves that elevate it. The term unspecified eyelid means the affected side is not documented.
Clinical signs
Typical findings include a visibly low upper eyelid, reduced eyelid opening, and possible visual obstruction. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states paralytic ptosis and does not identify the eyelid side. It fits cases where the provider documents eyelid droop from paralysis, weakness, or neurologic dysfunction without a more specific code.
Code it only when the documentation clearly links ptosis to a paralytic cause. If the note identifies the right or left eyelid, use the more specific code instead.
Do not use for
Do not use this code for congenital ptosis, mechanical eyelid droop, or unspecified ptosis without a paralytic cause. Check documentation.
Coding tip
Verify that the provider documented both paralytic ptosis and an unspecified eyelid before assigning H02.439.
