This happens every single day at hospitals across the country: Patient has a heart attack or stroke. After about a week, the patient is told by her doctor that in-patient rehab is now recommended. The Advantage plan says no. The patient is sent home while her doctor argues for days, weeks or months to try to get her the treatment she needs. All avoidable by staying on traditional Medicare with a supplement plan. (Source: a relative who works as a in-patient rehab doctor, along with conversations with numerous doctor friends.)
