ICD-10 Code H02.429 – Myogenic ptosis of unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.429 – Myogenic ptosis of unspecified eyelid
What it is
Myogenic ptosis is drooping of the upper eyelid caused by a muscle disorder affecting eyelid elevation. This unspecified eyelid code is used when the record does not identify right or left.
Clinical signs
Typical findings include a drooping upper lid, reduced palpebral fissure, and possible visual obstruction. Clinical features vary; refer to documentation.
When to use this code
Use H02.429 when the provider documents myogenic ptosis and does not specify the affected eyelid. It fits cases where the cause is muscular rather than neurologic or mechanical. If laterality is documented, select the more specific code instead.
Do not use for
Do not use this code for ptosis caused by nerve injury, trauma, or excess eyelid tissue. Check documentation if the note describes acquired, congenital, or mechanical ptosis.
Coding tip
Confirm both the cause and laterality in the chart before assigning H02.429.
