ICD-10 Code H02.419 – Mechanical ptosis of unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.419 – Mechanical ptosis of unspecified eyelid
What it is
Mechanical ptosis is drooping of the upper eyelid caused by a physical weight or mass, not by nerve or muscle weakness. “Unspecified eyelid” means the record does not identify the right or left side.
Clinical signs
Typical findings include a visibly lowered eyelid that may partially cover the pupil and interfere with the visual field. Clinical features vary; refer to documentation for the underlying cause, such as edema, scarring, or a lesion.
When to use this code
Use H02.419 when the provider documents mechanical ptosis and does not specify which eyelid is affected. This code fits cases where the droop is due to a mass, swelling, or other mechanical factor. Check documentation if the note identifies a side.
Do not use for
Do not use this code for ptosis caused by neurologic, myogenic, or congenital conditions. If the chart specifies a right or left eyelid, use the laterality-specific code instead.
Coding tip
Confirm the cause of the ptosis and the documented laterality before assigning H02.419.
