ICD-10 Code H02.203 – Unspecified lagophthalmos right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.203 – Unspecified lagophthalmos right eye, unspecified eyelid
What it is
H02.203 identifies lagophthalmos affecting the right eye when the eyelid cannot close fully. Use this code when the documentation does not specify the cause or the eyelid involved beyond the right side.
Clinical signs
Typical findings include incomplete eyelid closure, visible sclera during attempted closure, and exposure-related irritation. Clinical features vary; refer to documentation.
When to use this code
Use H02.203 when the provider documents lagophthalmos of the right eye and does not name a more specific cause or eyelid abnormality. It also fits cases described as unspecified lagophthalmos with right-sided involvement. Code only what is documented; check documentation if the record is unclear.
Do not use for
Do not use this code for left eye or bilateral lagophthalmos, or when a more specific diagnosis is documented. Avoid it if the chart identifies a distinct eyelid disorder instead of unspecified lagophthalmos.
Coding tip
Confirm laterality and specificity in the note before assigning H02.203.
