You said you read it, but did you call and ask. I generally get better answers when I call Medicare or whoever your insurance carrier is.

I think hospice is well defined because it's at one end of the spectrum and so much of what's covered makes sense. When my dad was in hospice he bounced between skilled nursing (the closest thing to ICU) to hospice care at home and Medicare paid for every thing except the mandatory 24X7 care provider. I learned more about my father and changed more of his diapers with lover than I imagined.
I am with a great palliative care provider here in Col Sp. To me they are #1 a supliment to pain management. They work with me on my ever changing pain issues. #2, They ask about and deliver quality of life issues and provide solutions. Psychic, emotional, spiritual, physical, limitations. They are a great consier into the "healing" world/business/solutions. And if I can get insurance to pay for it, I'll go to a WWII morphine drip dispenser aperatic in Sunny South Beach Miami.
You definitely need to get a good definition of "HomeBound". Bring some examples of what you think each is. I also palliative has much looser rules and you can talk them into stuff.

I’m using palliative care and I’m definitely not homebound. So far they’ve augmented my regular treatment with alternative medication when I had an issue. Of course I checked their suggestions with my doctor. I’ve had 2 appointments and will go again later this week. But as you said it may depend on your insurance coverage.

I experienced bilateral neuropathy in my feet to the point I was in tears sometimes. My oncology team referred me to palliative care. I never had an issue with my insurance covering my palliative care. I would definitely recommend that you contact your insurance company directly for clarification. If the insurance is denying palliative care then I suggest that your oncology team do a peer to peer whereas the oncologist explains to the insurance physicians why you need this care. I hope this helps.
