I want to find all patients with a diagnosis of hyperlipidemia, specifically other and unspecified hyperlipidemia, within the category of disorders of lipoid metabolism under the broader category of metabolic and immunity disorders. The search will include any time period, and the specificity scale is set to 0, meaning that all relevant cases will be included. The accuracy scale is set to 100, indicating a high level of accuracy. This query is part of a panel with a panel number of 1, and the panel timing is set to ANY. The panel's accuracy scale is also set to 10. There is only one item in this panel, and the item is not inverted. The hierarchy level is set to 4, and the icon used for this item is LA. The tooltip provided is "Diagnoses \ Metabolic and immunity disorders \ Disorders of lipoid metabolism \ Other and unspecified hyperlipidemia." The class for this item is ENC, and it is marked as a synonym.
