Physicians gather a treasure trove of data on care they provide to Medicare
beneficiaries. The aggregate information is invaluable and has been the basis
for scientific studies published in the Journal of the American
Medical Association and elsewhere.
However, such data have not been routinely collected on care provided
to the 6 million beneficiaries in Medicare + Choice plans (health maintenance
organizations [HMOs] and other private plans under contract with Medicare).
That is changing, and physicians need to know why and how it affects them.
