ICD-10 Code H02.159 – Paralytic ectropion of unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.159 – Paralytic ectropion of unspecified eye, unspecified eyelid
What it is
This code identifies outward turning of an eyelid caused by facial nerve weakness or paralysis, when the eye and eyelid are not further specified. Use it when the record documents paralytic ectropion but lacks laterality detail.
Clinical signs
Typical findings include lower eyelid eversion, tearing, irritation, and incomplete eyelid closure. Clinical features vary; refer to documentation for the affected eye and eyelid specifics.
When to use this code
Use H02.159 when the provider documents paralytic ectropion and does not specify right or left eye, or the exact eyelid involved. It also fits when the note confirms facial palsy-related eyelid malposition but laterality is missing. Query if the chart supports a more specific code.
Do not use for
Do not use this code for involutional, cicatricial, or mechanical ectropion, or for simple eyelid laxity without paralysis. If documentation names a different cause, code that condition instead.
Coding tip
Check the note for laterality and cause first; unspecified codes are appropriate only when those details are truly absent.
