A Checkup for Obamacare

Some facts (space doesn't permit me to go into every detail) to back up these assessments:

Coverage. More than 16 million Americans have gained insurance, including through the state and federal exchanges, the expansion of the Medicaid and Children's Health Insurance Program, and the requirement that children be allowed to remain on parents' policies until age 26, according to the Department of Health and Human Services.

The increase would be even greater had the Supreme Court not made the Medicaid expansion optional for states, of which 27 have accepted generous federal funding to cover those earning up to 138 percent of the poverty level. Still, the share of uninsured among the nonelderly (those over 65 obtain health care through Medicare) is at its lowest level ever recorded.

As predicted, millions remain without coverage. According to a January analysis by the Congressional Budget Office, in 2015, 36 million nonelderly people will be uninsured. By 2025, that number will drop to 31 million, one in nine nonelderly residents.

Of those, about 30 percent are unauthorized immigrants ineligible for help; 10 percent are ineligible for Medicaid because their states chose not to expand coverage; 15 percent to 20 percent are people eligible for Medicaid but not enrolled; and the rest (40 percent to 45 percent) simply decided not to purchase insurance.

Costs. Health care costs and premiums for employer-sponsored insurance (the way most of us obtain coverage) have been rising at their lowest levels in years. On the exchanges, premium increases during the law's second year mirrored that modest growth -- averaging 2 percent on some midrange plans and 4 percent on the lowest-cost ones, according to the Kaiser Family Foundation.

Subsidies are available for those with incomes up to 400 percent of the poverty level; 85 percent of those purchasing insurance on exchanges obtained monthly subsidies, averaging $263 in the 37 states participating in the federal exchange, according to HHS. More than half selected plans with monthly premiums of $100 or less, after subsidies.

Still, some individuals encountered sticker shock. While average premiums fell in 14 states, 10 states saw double-digit increases, according to The Commonwealth Fund.

Relatedly, slower growth in health spending has saved the government money. According to the CBO, the net cost of coverage provisions for the five years ending in 2019 will be 20 percent ($139 billion) less than originally projected.

That's a snapshot of the reality of reform. Not that it's apt to make much of a dent in the overheated rhetoric.
