What does Medicare NOT cover regarding private duty nursing?

Medicare does not cover care considered not medically necessary, which is why this choice is the correct answer. Medicare has specific guidelines regarding what constitutes medically necessary services, and any care that does not meet these criteria will not be covered.

Private duty nursing often includes personalized care that may not align with Medicare's definition of medically necessary services, especially if the care is deemed to be for convenience rather than essential health needs. Therefore, if a patient's required care is classified as non-essential, Medicare will not provide coverage for those services.

The other choices involve aspects of care Medicare does address under certain circumstances. For instance, while there may be limits, Medicare does cover some nursing services provided they meet the criteria for necessity and appropriateness. Care provided by registered nurses (RNs) can be covered when it's part of a personalized plan under the patient's home health services. As for short-term rehabilitation, it can also be eligible for coverage, particularly if it's part of a recovery process following an illness or surgery. However, if any of these services are deemed not medically necessary, they would fall under the same exclusion as other forms of non-essential care.
