Do I need a doctor’s note to have a nurse help my mother with her medications??

Have a very Happy Easter and/or Spring.

Thank you vhiett and Lilliput. I'll use this going forward. My Mom went in for a pacemaker and has been home 1 week and all of the sudden is experiencing trouble with her puffer.(She has used an inhaler off and on for the last 6 months.) Can't seem to use it right and is having a hard time all the way around. I'm worried about her so thank you for your input and help. Have a nice Easter---not PC but if you are both Christian then I hope you enjoy your day otherwise, have a nice weekend and thanks again.

You can hire a private RN either on your own or through an agency. If you want Medicare to pay for it you will have to go through the doctor. Also Medicare has a cap on $ for home health care. They also limit the number of times they come by setting a criteria that they establish and then say they met at which time they will stop coming and then you will have to hire your own.

You, personally, can hire anyone for in-home care. However, if you are trying to qualify for Medicare benefits or need to follow insurance guidelines, you need to speak directly to those entities.
As far as I know, Medicare only provides in-home care after a hospital stay - and only for a few weeks. (If your Mom qualifies for Medicaid, they may have different rules. Also, have you looked into veterans benefits, if applicable?)
And yes, you always need a doctor's order for any Medicare covered assistance. Check with your insurance - I will assume it is the same.
However, if you hire privately (out-of-pocket), you do not need "permission" from anyone. RNs cost more than CNAs or other paid caregivers.
good luck

Thanks Lilliput. Just to clarify, I can hire an RN without a Dr. order to do so? I'm in the process of figuring out Medicare and my parents supplemental coverage so wasn't sure if to get it covered somewhat by either source I needed an order.

CNAs and paid caregivers, in general, cannot administer medication. They can give their charges reminders and help them with water, etc.
As far as I know, if you need someone who will measure out any medicine or pills and give them to her directly, it will have to be an RN.
