H47.619 ICD-10-CM Code: Cortical blindness, unspecified side of brain

H47.619 is the ICD-10-CM diagnosis code for cortical blindness, unspecified side of brain. Cortical blindness is vision loss caused by damage to the part of the brain that processes sight (the visual cortex), rather than from problems with the eyes themselves. The unspecified side notation means the documentation does not indicate whether the damage is on the left side, right side, or both sides of the brain. H47.619 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).

H47.619 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.

Query the provider if documentation specifies which side of the brain is affected, as codes H47.611 (right side) and H47.612 (left side) are more specific and may be more appropriate than the unspecified code.
