My 83 mom has just been moved to a SNF for rehab after being in ICU for 2 weeks. Her rehab will most likely be at at minimum 2 weeks. I know Medicare will pay for 20 days at 100% and then an additional 80 at 80%. She fell, broke 11+ ribs, punctured a lung, and has mitral valve regurgitation. Despite all these issues, she is of sound mind, and I anticipate she may refuse treatment in the SNL after a couple days. If she does, will Medicare cut her off from future SNF benefits?
