Some of you misunderstood my post which was badly phrased. Sorry.
Medicare pays for Tom's meds in the nursing and/or at home. In order to get coverage for intravenous antibiotics while living AT HOME, through Medicare, the maximum allowed dosage is three shots per week. And that has to be administered in a "medical" setting.

Tom requires six per day. The only way Medicare will pay for that is if he is in a nursing home. The link I posted takes you to several sites discussing the merits (or lack of)of this rule.

If he had Supplemental Insurance, there would be no question. So it is not related to quality of care and since it costs much more it is not a savings for Medicare. In short, it makes no sense.

But it is a "rule" so it appears Tom is stuck. We'll see.
