ICD-10-CM Code R48.3
Visual agnosia

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

R48.3 is a billable ICD code used to specify a diagnosis of visual agnosia. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code R483 is used to code Prosopagnosia

Prosopagnosia /ˌproʊsoʊpæɡˈnoʊziə/ (Greek: "prosopon" = "face", "agnosia" = "not knowing"), also called face blindness, is a cognitive disorder of face perception where the ability to recognize familiar faces, including one's own face (self-recognition), is impaired, while other aspects of visual processing (e.g., object discrimination) and intellectual functioning (e.g., decision making) remain intact. The term originally referred to a condition following acute brain damage (acquired prosopagnosia), but a congenital or developmental form of the disorder also exists, which may affect up to 2.5% of the population. The specific brain area usually associated with prosopagnosia is the fusiform gyrus, which activates specifically in response to faces. The functionality of the fusiform gyrus allows most people to recognize faces in more detail than they do similarly complex inanimate objects. For those with prosopagnosia, the new method for recognizing faces depends on the less-sensitive object recognition system. The right hemisphere fusiform gyrus is more often involved in familiar face recognition than the left. It remains unclear whether the fusiform gyrus is only specific for the recognition of human faces or if it is also involved in highly trained visual stimuli.

Psychophysical visual disturbances (approximate match)

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code R48.3 and a single ICD9 code, 368.16 is an approximate match for comparison and conversion purposes.
