ICD-10-CM Code H47.649
Disorders of visual cortex in (due to) vascular disorders, unspecified side of brain
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
H47.649 is a billable ICD code used to specify a diagnosis of disorders of visual cortex in (due to) vascular disorders, unspecified side of brain. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code H476 is used to code Cortical blindness
Cortical blindness is the total or partial loss of vision in a normal-appearing eye caused by damage to the brain's occipital cortex. Cortical blindness can be acquired or congenital, and may also be transient in certain instances. Acquired cortical blindness is most often caused by loss of blood flow to the occipital cortex from either unilateral or bilateral posterior cerebral artery blockage (ischemic stroke) and by cardiac surgery. In most cases, the complete loss of vision is not permanent and the patient may recover some of their vision (Cortical visual impairment). Congenital cortical blindness is most often caused by perinatal ischemic stroke, encephalitis, and meningitis. Rarely, a patient with acquired cortical blindness may have little or no insight that they have lost vision, a phenomenon known as Anton–Babinski syndrome.
