Notes:

In the the original Medicare plan (also known as fee-for-service), accepting assignment means that the physician agrees to accept Medicare's approved amount as payment in full.

The assignment rate refers to the percent of Medicare-allowed charges for physicians' services billed on assignment. The rates are calculated based on the ratio of assigned allowed charges to total allowed charges (which reflects both assigned and unassigned allowed charges) for all physician services. Supplier services are excluded from this table.
