Two separate reports by the Centers for Medicare and Medicaid Services (CMS) and Health Affairs builds upon earlier research to conclude that private insurance plans under the Medicare Advantage program drive up Medicare spending. Ultimately, those private plans raise health care costs by encouraging seniors to cherry pick their health plans respective to their health, Kaiser Health News reports.

Private insurance plans under Medicare Advantage are often able to attract healthier Medicare beneficiaries by offering cheap — but bare-bones — health plans. When those healthier seniors encounter a medical problem that’s too extensive for their private coverage, they switch over to the more generous traditional Medicare program in order to take advantage of its more expansive benefits. That in turn, raises spending in the traditional Medicare pool:

A study released Thursday, by Gerald Riley, a researcher at the Centers for Medicare & Medicaid Services (CMS), adds to those concerns. The study looked at more than 240,000 people who dropped out of Medicare Advantage plans in 2007, and compared them with beneficiaries who remained in traditional Medicare the entire time. In the six months after leaving the private plans, the former Medicare Advantage patients used an average of $1,021 in medical services each month, while the patients in the control group cost Medicare $710 a month, the study found.

Another study in the December issue of the journal Health Affairs found thatpeople “disenrolling were much more likely than other beneficiaries to report health declines.” Those researchers, led by J. Michael McWilliams, a Harvard Medical School professor, surmised that beneficiaries who developed serious ailments might leave the plans to get unfettered access to physicians and treatments through traditional Medicare, but neither that study nor Riley’s determined what motivated the changes.
