The Obama administration released new regulations Monday on some key provisions of the Patient Protection and Affordable Care Act, including Medicaid expansion and state exchanges.

Health and Human Services Secretary Kathleen Sebelius said the proposed rule promotes consistent policies and processes for eligibility notices and appeals in Medicaid, the Children's Health Insurance Program and exchanges and give states more flexibility when operating their Medicaid programs. HHS said they encourage all Americans to review and submit comments on the proposed rule.

"Before the health care law was passed, millions of Americans were unable to obtain or afford quality health coverage," Sebelius said in a statement. "Today, we are proposing a rule to provide Americans with access to affordable, high quality health coverage and give states more flexibility to implement the law in a way that works for them."
