ICD-10 Code H02.40 – Unspecified ptosis of eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.40 – Unspecified ptosis of eyelid
What it is
H02.40 identifies drooping of the upper or lower eyelid when the record does not specify the cause, side, or type. Use it when the provider documents ptosis but gives no further detail.
Clinical signs
Typical findings include a visibly lowered eyelid margin and possible partial obstruction of the pupil or visual axis. Clinical features vary; refer to documentation.
When to use this code
Use this code when the note states ptosis of the eyelid and does not document congenital, acquired, mechanical, neurogenic, myogenic, or other specified ptosis. It also fits when laterality is not provided and no more specific code can be assigned. Check documentation if the record suggests an underlying disorder.
Do not use for
Do not use H02.40 if the provider documents a more specific eyelid ptosis type or a clearly related condition with its own code. Do not code it for general eyelid swelling or drooping that is not documented as ptosis.
Coding tip
If the chart only says “ptosis,” query for laterality and cause before defaulting to H02.40.
