How do insurance companies interfere with doctors' ability to provide necessary care to patients?

Insurance companies frequently obstruct medical care through mechanisms like prior authorization, where they evaluate whether prescribed treatments are merited despite the doctor's clinical judgment. Dr. Reinhart describes situations where physicians know exactly what patients need—especially in critical cases like suicidal patients—yet insurance companies can delay or deny treatment. This creates a frustrating scenario where doctors must wait for insurance approval, which can take days or weeks, potentially leaving vulnerable patients without necessary medication. The process undermines physicians' expertise and creates dangerous gaps in care delivery, highlighting a system where insurance companies effectively override medical decisions made by trained professionals.
