ICD-10 Code H11.213 – Conjunctival adhesions and strands (localized), bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.213 – Conjunctival adhesions and strands (localized), bilateral
What it is
Use this code for localized fibrous adhesions or strands involving the conjunctiva in both eyes. It describes a structural eye finding, not a general redness or infection.
Clinical signs
Findings may include visible conjunctival bands, tethering, or scarring on exam. Clinical features vary; refer to documentation.
When to use this code
Assign H11.213 when the record clearly documents bilateral localized conjunctival adhesions or strands. Use it for chronic or residual conjunctival scarring when the provider identifies both eyes and does not describe a different primary disorder. Check documentation if laterality is unclear.
Do not use for
Do not use this code for conjunctivitis, pterygium, or generalized conjunctival scarring without documented adhesions or strands. If the note does not specify bilateral involvement, check documentation.
Coding tip
Confirm the provider’s laterality and anatomic wording; bilateral must be stated or clearly implied in the record.
