I want to find patients with a diagnosis of Esophageal reflux, with any specificity and time range, using the ICD-10 code (530.81) for Other specified disorders of the esophagus, in the Digestive system category, within the Diseases of the esophagus subcategory, under the broader category of Diagnoses. This query should be applied to all data and has a high accuracy scale of 100.
