Question: If my cardiologist documented orthostatic hypotension, what ICD-10 code should I report for this condition? Delaware Subscriber Answer: You should report I95.1 (Orthostatic hypotension) for orthostatic hypotension. Orthostatic hypotension defined: Orthostatic hypotension (aka postural) relates to a drop in blood pressure when patients go from sitting to standing. This reading is in comparison to the patient’s blood pressure while sitting. Caution: You must check the medical record carefully to make sure the cardiologist specifically documented orthostatic hypotension, along with the patient’s vitals.
