What This Code Means
H20.039 is the ICD-10-CM diagnosis code for secondary infectious iridocyclitis, unspecified eye. Inflammation of the iris and ciliary body caused by or secondary to an infection when the specific eye is not documented. H20.039 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of sclera, cornea, iris and ciliary body (h15-h22).
H20.039 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.
