The USPSTF is an artifact of Obamacare. If it concludes tah something is essential then it gets covered. If it concluded it is not then it is not covered.
As the NY Times notes:
Under the Affordable Care Act, most insurance plans must fully cover services that it assigns an “A” or “B” grade. That gives the panel’s 16 volunteer members significant influence over the care Americans can afford. Over the past year, Mr. Kennedy has undermined the task force’s work, including by not replacing members whose terms ended in December. The task force issued fewer recommendations than is typical last year and missed a deadline for a legally mandated report to Congress after Mr. Kennedy postponed its meetings indefinitely.
Well the classic incompetence in my opinion and in my experience was their rejection of PSA tests for older men. It was based upon flawed trials in Europe and the US. One key flaw was the PSA tests were given just once every 4 years. Aggressive prostate cancer goes from nothing to death in less time. Annual PSA would likely save these lives. This fifteen years later the extended trial demonstrated this but the USPSTF never got the message.
Likewise breast cancer kills women in their 80s but they were denied screening by this jumbled mass of bureaucrats.
Now Kennedy and in turn is dumping this deadly organization which in my opinion is essential and far to late for the lives lost by their incompetence.
