The American Medical Association (AMA) blasted the Senate GOP's newly released "skinny" ObamaCare repeal bill Thursday evening as a "toxic prescription that would make matters worse."

The bill, released hours before it will be voted on, would repeal ObamaCare's individual insurance mandate and medical device tax, repeal the employer mandate for eight years as well as defund Planned Parenthood and increase contribution limits to health savings accounts for three years.

"Eliminating the individual mandate will lead to adverse selection , triggering higher premiums and further destabilizing the individual market," AMA President David O. Barbe said in a statement.

"The stated goal was to advance policies to lower premiums, but the ‘skinny’ bill would do the exact opposite, harming patients across the country."

Barbe urged senators to oppose the bill and pivot to a bipartisan effort "working through appropriate committees of jurisdiction and regular order to fix problems and gaps in current law to enable Americans to obtain quality, affordable health insurance.”

Leaders want to pass a "skinny" bill that contains provisions that they think can get the 50 votes needed to pass a healthcare bill out of the Senate.

Senate Republicans have struggled to coalesce around a comprehensive repeal and replace effort, and the "skinny" plan is a last-ditch effort to move a measure.

GOP leaders want to go to a conference with the House on the measure, hoping that it will result in a more comprehensive plan.
