Hospitals’ growing practice of re-labeling Medicare patient readmissions as “observation stays,” or treating returning Medicare patients in the emergency room, has allowed many hospitals to skirt Medicare’s financial penalties for poor-quality performance that were mandated by the Affordable Care Act, researchers say.

Another benefit of a single payer national health insurance system is that it gets rid of the obscenity of the revolving door between the health insurance industry and the government payer.

There is no revolving door because there is no door.
