ICD-10 Code H02.21B – Cicatricial lagophthalmos left eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.21B – Cicatricial lagophthalmos left eye, upper and lower eyelids
What it is
This code identifies inability to fully close the left eye because scarring has shortened or tightened both eyelids. It applies when the upper and lower lids are involved and the cause is cicatricial, or scar-related.
Clinical signs
Typical findings include incomplete eyelid closure, visible lid scarring, and exposure of the ocular surface. Clinical features vary; refer to documentation for laterality and whether both eyelids are affected.
When to use this code
Use H02.21B when the record clearly documents cicatricial lagophthalmos of the left eye with both upper and lower eyelids involved. This may follow trauma, surgery, burns, or other scarring conditions, but code only what is documented.
If the note does not specify the left side or does not confirm both lids, check documentation before assigning this code. Use the most precise lagophthalmos code available.
Do not use for
Do not use this code for non-scar-related lagophthalmos, unspecified eyelid closure problems, or right-eye involvement. Check documentation if the cause or laterality is unclear.
Coding tip
Verify both laterality and the cicatricial cause in the chart, because these details determine whether H02.21B is correct.
