Can Adults Get Health Insurance Coverage under Obamacare Despite Having a Pre-Existing Condition? - YES
The Centers for Medicare and Medicaid Services (CMS) stated in their Feb. 23, 2012 annual report “Covering People with Pre-existing Conditions: Report on the Implementation and Operation of the Pre-existing Condition Insurance Plan Program,” available at www.cciio.cms.gov:
"The law [PPACA] ends discrimination against people with pre-existing conditions. Insurers can no longer deny coverage to children because of a pre-existing condition and starting in 2014, refusing to cover anyone with a pre-existing condition is prohibited.”
Abby Matienzo, Communications Specialist at the National Academy of Elder Law Attorneys (NAELA), wrote in a Mar. 23, 2012 press release "National Academy of Elder Law Attorneys Celebrates Two-Year Anniversary of Affordable Care Act," available at www.naela.org:
"Coverage despite pre-existing conditions: In 2014, health insurance companies will no longer be able to deny coverage to beneficiaries due to a preexisting condition. Protections are already in place for certain individuals with pre-existing conditions, with the ACA's sponsorship of high-risk health insurance plans for individuals with pre-existing conditions. As of November 2011, 450,000 individuals were participating in these plans."
