I'm not sure what your locale is.
Here in the midwest (where there are a lot of old people) this doesn't seem to be the case, thankfully.
For better or worse, I've had a lot of personal experience with medical providers since I retired.
Nationally the percentage is about 91% of doctors take medicare patients.
That is good to know. Perhaps the "discount" is not as great a hit as I believed.
nasc...... I live in Golden CO. My doctor no longer accepts Medicare or Medicaid patients. Can’t afford to. :-(
