Thanks for the input. I do have Medicare along with the Aetna Direct I signed up for after my retirement from the federal government. Pretty good coverage. Neither my wife nor I have had a medical bill since my retirement in 2017.

I think I will contact the PA at my local VA to inquire further about VA footing the bill. While my VA oncologist seems to know something about Waldenstrom's, she is certainly not a WM expert or a hematologist/pulmo doc. A case might be made here.

As a former Marine, I will never give in and never, ever give up. Thanks.
