ICD-10 Code H02.4 – Ptosis of eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.4 – Ptosis of eyelid
What it is
H02.4 identifies drooping of the upper or lower eyelid. Use it when documentation states ptosis and the record does not specify a more detailed eyelid disorder.
Clinical signs
Ptosis is seen as an abnormally low eyelid position that may partially cover the pupil. Clinical features vary; refer to documentation for laterality, severity, or any associated functional impairment.
When to use this code
Use H02.4 when the provider documents ptosis of the eyelid without a more specific subtype. It fits office, specialist, or problem-list documentation that simply notes eyelid droop. If the chart names a cause or a different eyelid condition, code that diagnosis instead.
Do not use for
Do not use this code for general facial weakness, brow ptosis, or other non-eyelid drooping. Check documentation if the eyelid finding is part of trauma, neurologic disease, or a postoperative complication.
Coding tip
Capture laterality and any documented cause whenever the note supports a more specific code.
