I want to find all patients with a diagnosis of diseases caused by Coronavirus, classified under ICD-10 codes B95-B97, specifically under the subcategory B97.2, where the cause is specified as a Coronavirus infection. The query will return results with any timing and has a specificity scale of 0, indicating a broad search, with an accuracy scale of 100, indicating a high level of confidence in the results. This query will focus on a single panel, with a single item occurrence, and will not be inverted. The hierarchy level is set at 4, and the query will return results for Coronavirus as the cause of diseases classified elsewhere, using the provided tooltip as a guide for further understanding.
