ICD-10 Code H02.59 – Other disorders affecting eyelid function (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.59 – Other disorders affecting eyelid function
What it is
H02.59 identifies eyelid function problems that do not fit a more specific eyelid diagnosis. Use it when documentation describes an eyelid disorder affecting movement or closure, but does not name a narrower condition.
Clinical signs
Clinical features vary; refer to documentation. You may see abnormal eyelid position, impaired blinking, poor lid closure, or functional disturbance noted on eye examination.
When to use this code
Use this code when the record clearly states an unspecified or other eyelid functional disorder and no more specific ICD-10-CM code applies. It is appropriate for ophthalmology notes that describe eyelid dysfunction without naming ptosis, ectropion, entropion, or another defined disorder. Check documentation if the exact eyelid condition is unclear.
Do not use for
Do not use H02.59 when the chart supports a specific eyelid diagnosis with its own code. Avoid it for cosmetic concerns or nonspecific eye complaints without documented eyelid dysfunction.
Coding tip
Code the most specific eyelid diagnosis documented; if the note only says “other eyelid dysfunction,” H02.59 is appropriate.
