If you want to be a supervisor in a SNF, it seems you should at least have a basic knowledge of the regs. MDS=minimum data set....questions which need to be answered according to the rules and the set schedule and submitted to medicare for payment. Medicare rules are cumbersome but certainly a supervisor needs to have more than a nodding acquaintance with them. Medicare pays for certain things not for others...pays the entire bill for the first 20 days, then there is a copay. Working in a SNF is not just about nursing skills these days. You have to be an accountant as well.
Case managers in LTC deal more with insurance companies...you follow the pt from the day she is admitted to maximize the amount of money you get paid and maximize the benefit to the patient.
