What should you ask Mt. Sinai at Home before starting care?
Ask who answers after hours
Problems rarely wait for office hours. Ask whether the night and weekend line reaches one of their own nurses or an answering service, and how long a call-back usually takes.
Ask how many visits a week to expect
Home health is intermittent: visits, not shifts. Ask for the planned number of nursing and therapy visits per week so the family knows which hours still need covering.
Ask whether your plan treats it as in-network
Original Medicare pays any certified agency. Medicare Advantage plans use networks, and an out-of-network agency can mean a denied claim. Give them the exact plan name on the card.
