ICD-10 Code H02.156 – Paralytic ectropion of left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.156 – Paralytic ectropion of left eye, unspecified eyelid
What it is
This code identifies outward turning of the left eyelid caused by facial nerve weakness or paralysis. “Unspecified eyelid” means the record does not name the upper or lower lid.
Clinical signs
Typical findings include lid eversion, tearing, irritation, and incomplete eyelid closure on the left side. Clinical features vary; refer to documentation for the affected eyelid and cause.
When to use this code
Use H02.156 when the provider documents paralytic ectropion involving the left eye and does not specify which eyelid is affected. It may apply after facial nerve palsy, trauma, or other documented paralysis. Code from the provider’s stated diagnosis, not from symptoms alone.
Do not use for
Do not use this code for nonparalytic ectropion, bilateral disease, or right-eye involvement. If the record specifies upper or lower eyelid, choose the more specific code.
Coding tip
Check the note for laterality and eyelid detail before assigning H02.156.
