ICD-10 Code H02.155 – Paralytic ectropion of left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.155 – Paralytic ectropion of left lower eyelid
What it is
Use this code for outward turning of the left lower eyelid caused by facial nerve weakness or paralysis. The lid no longer rests against the eye, which can leave the surface exposed.
Clinical signs
Typical findings include lid eversion, tearing, irritation, and poor eyelid closure on the left side. Clinical features vary; refer to documentation.
When to use this code
Assign H02.155 when the record clearly identifies paralytic ectropion affecting the left lower eyelid. Use it for documented facial nerve palsy or paralysis with eyelid malposition, when laterality and lower lid are specified.
Check documentation if the chart only says ectropion, eyelid droop, or facial weakness without stating paralytic cause and left lower lid involvement.
Do not use for
Do not use this code for involutional, cicatricial, or mechanical ectropion. Also avoid it when the condition involves the upper eyelid or the side is not documented.
Coding tip
Confirm both paralytic cause and left lower eyelid laterality before coding; otherwise, check documentation.
