About coding fugax amaurosis
The ICD-10-CM code for fugax amaurosis is G45.3 (Amaurosis fugax).
Within G45 (transient cerebral ischemic attacks and related syndromes), G45.3 is specifically for Amaurosis fugax. Related codes cover Vertebro-basilar artery syndrome (G45.0), carotid artery syndrome (hemispheric) (G45.1), multiple and bilateral precerebral artery syndromes (G45.2), transient global amnesia (G45.4), other transient cerebral ischemic attacks and related syndromes (G45.8) and transient cerebral ischemic attack, unspecified (G45.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
In MS-DRG v44.0, it is part of the grouping logic for DRG 123 (Neurological Eye Disorders, relative weight 0.822), in MDC 02 (Diseases and Disorders of the Eye), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
