ICD-10 Code H02.225 – Mechanical lagophthalmos left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.225 – Mechanical lagophthalmos left lower eyelid
What it is
H02.225 identifies mechanical lagophthalmos affecting the left lower eyelid. It means the eyelid cannot close fully because of a physical obstruction or tissue problem.
Clinical signs
Typical findings include incomplete eyelid closure, exposed eye surface, and possible irritation or dryness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states mechanical lagophthalmos of the left lower eyelid. It fits cases where a structural cause prevents full closure, such as scarring, mass effect, or eyelid deformity. You should confirm laterality and that the condition is mechanical, not neurologic.
Do not use for
Do not use this code for nonspecific eye irritation or for lagophthalmos without documented left lower eyelid involvement. Check documentation if the cause is paralytic or the side is not stated.
Coding tip
Verify the exact eyelid and mechanism in the note before assigning H02.225.
