What This Code Means
H53.122 is the ICD-10-CM diagnosis code for transient visual loss, left eye. A temporary loss of vision in the left eye that resolves on its own, lasting from seconds to minutes. H53.122 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering visual disturbances and blindness (h53-h54).
H53.122 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.
Transient visual loss is temporary; document duration and resolution in medical record.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H53.122 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Transient visual loss is temporary; document duration and resolution in medical record
