It won't matter in this case
Health care reform has not kicked in yet, except in minor ways. And even when it does, in general it will not affect traditional Medicare coverage. Under Medicare Part A (hospital insurance) the patient pays an $1100 deductible and then an additional daily copay if the stay is longer than 60 days.
Extra unnecessary hospital days is one of the things that drives Medicare spending up, which is a negative impact to everyone.
