On Jan. 1, 2020, a new Medicare policy is scheduled to go into effect that will eventually require doctors to use a computer algorithm to vet imaging tests to determine “appropriateness.” If the tests, such as CT scans and M.R.I.s, do not meet certain “appropriate-use criteria,” Medicare may not reimburse the cost. Intended to reduce unnecessary imaging, the policy may penalize doctors who don’t comply by requiring them to get “prior authorization” before ordering imaging tests in the future — in other words, to follow another regulation.
Predictably, many doctors want the policy reversed or at least delayed so that they can come up with an alternative. They say that there is little evidence that the regulation will achieve its intended aim. They have concerns about how the computer algorithm will interact with existing electronic medical records. More generally, they complain of burdensome regulations, created largely without physician input, that doctors already must follow. The new policy, they say, is another intrusion on physicians’ decision-making authority — an authority gained over many years of difficult training.
These are all valid points, and yet after almost six years of delays — the law was passed in 2014 — doctors have not advanced an alternative solution. Meanwhile, billions of dollars continue to be spent every year on unnecessary imaging, creating not just financial waste but also real risks to patients, including excess radiation and false-positive diagnoses. If doctors can’t or won’t fix a problem that is almost universally acknowledged in our profession, should we act outraged or surprised when an outside agency tries to do it for us?
To be fair, medical specialty societies such as the American Board of Internal Medicine have published lists of imaging tests that are generally not beneficial to patients, including M.R.I.s for most lower back pain and stress tests when there are no signs of heart disease. Using these criteria, doctors on their own have been able to reduce the volume of imaging.
