Insurance companies working under the Obamacare umbrella have secretly added a surcharge to cover the cost of abortions, an apparent violation of federal law that forbids the practice, congressional leaders charge.

Consumers signing up for insurance in an Obamacare exchange won't find a single sentence telling them that they will pay at least $1 a month to fund abortions.

"The president promised when the health care bill passed that it would not cover abortion. We knew that was an empty promise as the bill stipulated a $1 a month surcharge for plans that covered abortions," said Rep. Joe Pitts, R-Pa., who chairs the House's Energy and Commerce subcommittee on Health. "On top of that ... it's near impossible to decipher which plans include abortion and at what cost!"

To fix this, a House bill will be introduced this week to demand full disclosure and a separate itemized premium. It also will prohibit federal subsidies for Obamacare insurance plans that cover abortion. That bill, HR-7, or the "No Taxpayer Funding for Abortion Act," will be introduced by House Majority Leader Eric Cantor.

On Oct. 9, Rep. Chris Smith, R-NJ, introduced a bill on the disclosure issue, which now has been folded into the broader HR-7. Smith is co-chairman of the Bipartisan Congressional Pro-Life Caucus.

Aides with both Pitts and Smith have researched numerous Obamacare policies and have yet to find any mention of abortion.

"We can't find any insurance plans where this is disclosed," said Andrew Wimer, communications director for Pitts.
