I’ve worked in medicine my whole career and have seen how money infects the profession. Treatment is usually determined by what doctors can bill for and not always what is best for the patient.
Hospitals are no better. They tell doctors how to treat patients based on how they are be reimbursed.
The most powerful organizations in medicine are CMS and insurance companies. They dictate treatment with their reimbursement. If they aren’t reimbursing medical professionals and facilities for a treatment, nobody is getting that treatment.
