What This Code Means
H44.521 is the ICD-10-CM diagnosis code for atrophy of globe, right eye. Shrinkage or wasting away of the eyeball tissue in the right eye, often resulting from severe eye disease or injury. H44.521 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of vitreous body and globe (h43-h44).
H44.521 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Document the underlying cause of globe atrophy when possible, such as previous trauma, inflammation, or glaucoma.
