"The forecast shortage of doctors has become a real problem. It started in 2014 when the ACA cut $716 billion from Medicare to accommodate 30 million newly "insured" people through an expansion of Medicaid. More important, the predicted shortage of 42,000 primary-care physicians and that of specialists (such as heart surgeons) was vastly underestimated. It didn't take into account the ACA's effect on doctors retiring early, refusing new patients or going into concierge medicine. These estimates also ignored the millions of immigrants who would be seeking a physician after having been granted legal status.Read the whole thing (subscription required, sorry). Not surprisingly, it's not pretty.
It is surprising that the doctor shortage was not better anticipated: After all, when Massachusetts mandated health insurance in 2006, the wait to see a physician in some specialties increased considerably, the shortage of primary-care physicians escalated and more doctors stopped accepting new patients. In 2013, the Massachusetts Medical Society noted waiting times from 50 days to 128 days in some areas for new patients to see an internist, for instance.
But doctor shortages are only the beginning.
Even before the ACA cut $716 billion from its budget, Medicare only reimbursed hospitals and doctors for 70%-85% of their costs. Once this cut further reduced reimbursements, and the ACA added stacks of paperwork, more doctors refused to accept Medicare: It just didn't cover expenses.
Then there is the ACA's Medicare (government) board that dictates and rations care, and the board has begun to cut reimbursements. Some physicians now refuse even to take patients over 50 years old, not wanting to be burdened with them when they reach Medicare age. Seniors aren't happy."
Medicaid in 2016 has similar problems. A third of physicians refused to accept new Medicaid patients in 2013, and with Medicaid's expansion and government cuts, the numbers of doctors who don't take Medicaid skyrocketed. The uninsured poor now have insurance, but they can't find a doctor, so essentially the ACA was of no help.
The loss of private practice is another big problem. Because of regulations and other government disincentives to self employment, doctors began working for hospitals in the early 2000s, leaving less than half in private practice by 2013. The ACA rapidly accelerated this trend, so that now very few private practices remain."
