My 84-year-old mother has level 5-6 dementia and COPD. I have been told by a hospice provider that because she is not on oxygen for the COPD and is not diagnosed with anything other than COPD and dementia that she does not meet the criteria for hospice services. However, she can barely walk even with a walker and has to have assistance bathing and dressing and sometimes eating.
I should add my mom had no concrete diagnosis of anything other than FTT. She had lost over 10% of her weight in two months down to 72 pounds when she finally let us bring hospice into the picture. If you can demonstrate a very rapid decline, that should bring hospice into the picture.
I wish my mom would've allowed it earlier. She went through needless pain with her stubborn attitude.
I hope you get the support you and your mom deserve on your journey together.
