What This Code Means
H11.10 is the ICD-10-CM diagnosis code for unspecified conjunctival degenerations. Deterioration or breakdown of the conjunctiva (clear membrane covering the white of the eye) that cannot be more specifically classified. H11.10 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).
H11.10 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.
Use only when specific type of conjunctival degeneration cannot be identified.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for H11.10 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
