I want to find patients with a diagnosis of coronavirus as the cause of diseases classified elsewhere (ICD10_ICD9 code: B97.2) who have also had contact with and suspected exposure to communicable diseases (ICD10_ICD9 code: Z20). This query includes patients with any timing for both diagnoses and contact/exposure, and has a specificity scale of 0 and an accuracy scale of 100 for each panel. The query is not inverted and has a total of 1 occurrence for each item in the panel. The hlevel for the first item is 4 and the hlevel for the second item is 3.
