ICD-10 Code H02.206 – Unspecified lagophthalmos left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.206 – Unspecified lagophthalmos left eye, unspecified eyelid
What it is
This code identifies lagophthalmos affecting the left eye when the eyelid does not close fully, and the eyelid is not further specified. Use it when documentation confirms incomplete closure without a more precise cause or eyelid detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see incomplete eyelid closure, visible sclera during attempted closure, eye dryness, irritation, or exposure symptoms on the left side.
When to use this code
Use H02.206 when the record states lagophthalmos of the left eye and does not specify the eyelid involved. It also fits when the provider documents incomplete eye closure without naming a more specific disorder or cause.
If the note identifies a different eyelid, an underlying neurologic or traumatic cause, or a more specific lagophthalmos type, code that documented condition instead. Check documentation for laterality and specificity before assigning this code.
Do not use for
Do not use this code for bilateral or right-eye lagophthalmos, or when the provider documents a specific eyelid not matching the left eye. Also avoid it when another diagnosis better explains the incomplete closure.
Coding tip
Confirm both laterality and eyelid detail in the chart; if the left eye is specified but the eyelid is not, H02.206 is the correct choice.
