This nytimes article just reminds me how much I dislike Medicare Advantage as a concept and especially Private Fee for Service (PFFS). I do owe my extreme familiarity with the CMS website and Medicare Advantage in particular to it however. The Wellpoint PFFS plan started operating about one month after I started my first real job working in their Senior actuarial department. Unfortunately everyone who had worked on the product development or on the national Senior products in general had left the department already so I was thrown into tracking down and interpreting the data pretty much out of thin air. It was fairly stressful to say the least. I ended up with a crash course in all things Medicare Advantage - how payments to Health Plans were transmitted, demographic and risk adjustment, county payment rates, the working aged adjustment. Also a crash course in finding and interpreting incredibly obtuse data.
As for private health plans doing anything beneficial for Medicare - this testimony is spot on and proved to be quite accurate. I found it while looking for some inside dirt on why the plans were passed in the first place - I had a vague recollection of hearing or reading that it was because of some senator's wife wanting a private plan option. I wasn't aware of the right-to-life movement's large role in enacting that option. This brief has a lot of good information about the history and dynamics of PFFS. Just more examples of how all those hardcore right wingers work together to the detriment of the majority.
