Oh, so when my Medicare patients can't get coverage/approval for the medications that actually work and have to settle for cheaper, oftentimes less-effective, generic options that are covered (because they can't afford to pay out of pocket), that's "having little to no impact on physician choice or treatment options?"
And, of course, physicians have the choice to opt out of seeing Medicare patients. It's just an all or nothing deal. The physician either is or is not a Medicare provider. As for the reimbursement rates, they are just "ok." The difference between Medicare (in the real world) and the privately insured patient is that the physician effectively has no hope of ever being able to recoup the balance from the Medicare patient between what is reimbursed and what the service provided actually costs.
Oh, and then there's that lovely little habit Medicare has of simply suspending payment when they run out of money. I went SIX WEEKS last December and this January without a single penny being reimbursed. Why? No money. Then it takes FOREVER for them to play catch-up. My medical billing people are only NOW receiving the final payments from that lovely little glitch ten months ago. In 2008 or 2009 (I forget which) I went for MONTHS without reimbursement for the same reason.
Government-run health care SUCKS for physicians. The ONLY reason I still accept it is out of loyalty to my older patients. That's it. I'm BLEEDING money because no one else will take care of them to the standard I can.
Medicare is not a monolith in many of the respects to which you are referring.
As far as the treatment options point, it's unclear if you're talking about inpatient and physician-administered drugs (Parts A & B) or otherwise (Part D). Big difference here in terms of federal funding and its effect on the patient. Furthermore, generics
must be bioequivalent (.8-1.25 at 90% CI) to the brand, so, yes, I would characterize that as "little" difference. I have seen an increasing number of commercial plan tiered formularies that are as bad or worse than just about anything you see in the Medicare program as far as patient cost-sharing goes.
Regarding the coinsurance, Medigap plans are a wise investment for any Medicare beneficiary and inexpensive relative to their value of coverage. I can't imagine the gnashing of teeth over the cost of Medicare if the coinsurance was even half what it is now.
Being "government-run" for instance, the payment issues to which you refer could very likely be the fault of your regional fiscal intermediary, which is a
private entity providing processing and other administrative services for Medicare under a generally very strict contract. This is aside from the Medicare Advantage and Part D plans.
Despite one's feelings about Medicare, caring for seniors is a costly endeavor, and, if you look at the costs of Medicare Advantage plans versus traditional Medicare, it's not something the private sector insurance industry (with a few exceptions) has been able to show it can do more cost-effectively.
