Not Rummy but I did a search for Monoclonal Antibody infusion requirements in TN. Do a search for your state. Mine came from the TN Dept. of Health. In TN you can be eligible if you have pulmonary issues. I’m 66 with asthma so I qualify either way. Husband is 83. I think different states have different requirements.

Monoclonal Antibody database of locations where it’s available, all 50 states.
Closest place to me was a pharmacy so I guess one would have to ask the pharmacy for the names of doctors or hospitals that are providing the treatment.
