What the payments were

Each payment as the manufacturer categorized it when reporting it to CMS, across 2019–2025. Together they are the general payments above. A category is the reporter’s, and nothing in the record says a payment in any of them was improper.

By program year

CMS reports a program year at a time and also publishes its own total across them, which is what the figures above are. These rows are that total taken apart, not a second set of payments.

Interventional Cardiology

Prescriber type

As CMS classifies this prescriber. Credentials: MD.

A blank is not a zero. CMS withholds a value between 1 and 10, and withholds the next lowest alongside it so the first cannot be worked out by subtraction — so a withheld figure is not even evidence that the number was small. Rows for ten or fewer claims are removed from the file altogether, which is why the parts of a total can be withheld while the total is published.
