As you know, F01.50 requires a "first code" – psychological condition or sequelae of CVD/CVA. My coding book also has additional notes that specify "this type may also be related to other CVD including vascular hypertension and cerebral atherosclerosis." If the physician doesn’t specify a cause for the VD and there’s no history of CVD or a stroke, how would you fundamentally code without being able to query the physician? (Patient does have hypertension but no other cardiovascular issues.) Thanks coding community!
