What This Code Means
H47.612 is the ICD-10-CM diagnosis code for cortical blindness, left side of brain. Complete loss of vision caused by damage to the visual processing area on the left side of the brain, resulting in blindness despite healthy eyes. H47.612 sits in the ICD-10-CM chapter for diseases of the eye and adnexa (h00-h59), within the section covering disorders of optic nerve and visual pathways (h46-h47).
H47.612 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.
Verify the laterality is documented as left side in the clinical record before assigning this code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for H47.612 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Verify the laterality is documented as left side in the clinical record before assigning this code
- •Ensure the blindness is specifically due to cortical damage, not other causes like cataracts or retinal disease
