The Supreme Court said it will hear oral arguments on March 4 in a lawsuit over whether the Obama administration is improperly providing tax credits to consumers who purchase health insurance through the federal exchanges.

California's health insurance exchange said 144,178 people have newly enrolled in Obamacare coverage during the first month of sign ups.

Just days before the requirement for most large employers to provide health insurance takes effect, a new poll finds the public easily swayed over arguments for and against the policy.

Even though more Americans have access to health insurance because of the health law, getting access to mental health services may still be challenging.

More than 1 million people selected a health plan during the fourth week of the health law's open enrollment and nearly 2.5 million have done so since it began Nov. 15, federal officials said Tuesday.

People without insurance are running out of time to avoid the hefty ObamaCare penalties that the IRS will be handing down in 2016.
