What This Code Means

H11.242 is the ICD-10-CM diagnosis code for scarring of conjunctiva, left eye. Scarring or permanent damage to the clear membrane covering the white part of the left eye, often resulting from injury, infection, or inflammation. H11.242 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of conjunctiva (h10-h11).

H11.242 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.

Verify the laterality is specifically documented as left eye in the medical record.
