I want to find patients with a diagnosis of essential (primary) hypertension (I10) and diabetes mellitus (E08-E13) in any encounter, with 100% accuracy and no specificity scale, and the panel is set to "ANY" timing. The query will include two panels, the first panel focusing on essential (primary) hypertension and the second panel focusing on diabetes mellitus.
