I want to find all encounters where patients were screened for coronavirus infection, unspecified, using the ICD-10 and ICD-9 diagnosis codes, within a certain timeframe. The specificity scale is set to 0, meaning that all cases will be included, and the panel accuracy scale is set to 100, indicating high accuracy. The query will include two panels: the first panel will focus on diagnoses related to certain infectious and parasitic diseases, while the second panel will concentrate on encounters for screening for infectious and parasitic diseases.
