ICD-10 Code H02.41 – Mechanical ptosis of eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.41 – Mechanical ptosis of eyelid
What it is
Mechanical ptosis is drooping of the upper eyelid caused by a physical weight or mass on the lid, not by nerve or muscle weakness. You code this when documentation identifies a mechanical cause.
Clinical signs
Typical findings include a visibly low upper lid, reduced palpebral fissure, or lid obstruction from swelling, scarring, tumor, or other added weight. Clinical features vary; refer to documentation.
When to use this code
Use H02.41 when the provider documents ptosis as mechanical and ties it to a local eyelid or adjacent structure cause. It may apply when excess tissue, edema, or a mass produces the droop. Check documentation if the cause is not stated.
Do not use for
Do not use this code for congenital, neurogenic, myogenic, or unspecified ptosis. If the record only says “droopy eyelid” without a mechanical cause, you need clearer documentation.
Coding tip
Code the underlying documented cause first when it is separately reportable, and confirm laterality and specificity in the note.
