ICD-10 Code H02.403 – Unspecified ptosis of bilateral eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.403 – Unspecified ptosis of bilateral eyelids
What it is
H02.403 identifies drooping of both upper eyelids when the type or cause is not further specified. Use it when documentation states bilateral ptosis without additional detail.
Clinical signs
Typical findings include visible eyelid droop on both sides and possible obstruction of the visual axis. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents bilateral ptosis but does not name a cause, such as congenital, myogenic, or neurogenic ptosis. It also fits brief assessments that note “bilateral eyelid ptosis” without further characterization. If the provider documents a more specific diagnosis, code that instead.
Do not use for
Do not use H02.403 for unilateral ptosis or for ptosis with a documented specific cause. Check documentation if the eyelid droop is due to trauma, surgery, or another defined condition.
Coding tip
Assign H02.403 only when both eyelids are involved and the chart lacks a more specific ptosis diagnosis.
