Imagine your mom has a stroke. Once she is stabilized, she is sent to a skilled nursing facility for rehab. Then she goes home and gets some home health care and additional physical therapy. Medicare may pay, but for how long?
For many years, that was decided by the “improvement standard.” In other words, as long as this care helped mom become more mobile or improve her speech, Medicare would pay at least some of the cost (up to a maximum of 100 days per spell of illness). But once she stopped getting better, Medicare would stop paying.
