ICD-10 Code H02.042 – Spastic entropion of right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.042 – Spastic entropion of right lower eyelid
What it is
H02.042 identifies spastic entropion affecting the right lower eyelid, where the lid turns inward because of eyelid muscle spasm. This can cause the lashes to rub the eye.
Clinical signs
Look for inward rotation of the right lower lid, ocular irritation, tearing, and foreign-body sensation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents spastic entropion specifically in the right lower eyelid. It is appropriate when the note distinguishes the right lower lid from other eyelids or from unspecified entropion. Check documentation if the cause or eyelid side is unclear.
Do not use for
Do not use H02.042 for entropion of another eyelid, unspecified entropion, or ectropion. If the record does not confirm the right lower eyelid, use the documented site only.
Coding tip
Verify laterality and eyelid level in the ophthalmology note before assigning H02.042.
