Thirteen million people could become uninsured under the House Republican healthcare plan by 2026, according to an analysis from the Trump administration.

The analysis, completed by the chief actuary at the Department of Health and Human Services, differs substantially from an analysis of the same bill released last month by the Congressional Budget Office.

The CBO estimated that at least 23 million people could become uninsured under the American Health Care Act (AHCA) over a decade.

The actuary noted, however, that allowing states to waive out of some ObamaCare regulations could lead to a "deteriorating or possibly failing individual market," which is similar to a conclusion made in the CBO report.

"If such actions were implemented, we would expect that the individual market in these areas would destabilize such that premiums for comprehensive coverage for a significant proportion of the population would become unaffordable and the coverage would cease to be offered," the actuary wrote.

The new report will likely provide fodder for Senate Republicans trying to repeal ObamaCare, some of whom have cast doubt on the accuracy of the CBO report.

Senate GOP leaders have said they will write their own bill, but may take some ideas from the House bill.
