I want to find all encounters where the patient has a diagnosis related to the respiratory system (codes 460-519) and has been prescribed medications related to respiratory agents (LME219). This query is designed to identify patients with respiratory conditions who have been treated with respiratory agents, with no specific timing requirements and a high level of accuracy.
