Medicare is the largest insurer and payer for medical treatment In the
USA.  As such, it has its own price schedule of what those who
participate in its program may charge  for each medical procedure, and
what portion of it will be paid by Medicare.  Moreover, Medicare
dictate that in most cases no additional amount over the approved rate
may be charged to the patient.

For the sake of the issue I wish to raise, I will ignore the
complexities of Medicare Part A, Part B and medigap with its various
plans.  In essence, doctors and medical institutions are paid less
(substantially less) for treating medicare patients.

My question is how these facts affect the quality and quantity of care
and treatment provided to Medicare patients.
