The Obama administration recently cautioned that unanswered questions regarding immigration status and the legitimacy of citizenship may result in hundreds of thousands of people losing their taxpayer-subsidized insurance, which was recently granted to uninsured individuals nationwide under the Affordable Care Act, otherwise known as Obamacare.

The health care law granted subsidized insurance to those not offered insurance through their jobs. As a result, more than 80 percent of enrollees presently receive subsidies to assist with payments on premiums, and a smaller number receive assistance with the cost of copays and deductibles. To access this assistance, consumers were questioned about their income, home town, family size and other factors, resulting in consumers receiving the premium tax credit, which varies depending on an individual's responses.  

Now, individuals with questionable standing, based on discrepancies, have only until Sept. 5 to upload their documentation to HealthCare.gov or mail it in, otherwise their coverage will end Sept. 30.

At least 2 million of the 8 million people who signed up for private coverage through HealthCare.gov had files that showed discrepancies at one point or another, muddying their eligibility and access. During May, nearly 970,000 people experienced issues with citizenship and immigration, resulting in their access to health care being threatened.

Approximately half of those cases were closed, another 20 percent are being actively investigated, and the remainder remain unclear.   

The Health and Human Services Department has shared that approximately 310,000 people will receive letters in English and in Spanish about immigration and citizenship documentation issues, which reminds recipients that undocumented residents in the U.S. are not allowed health care subsidies.

The letters are expected to reach many in the Latino community. Florida (93,000 cases) and Texas (52,700 cases) top the list for unresolved cases, and both states have huge Latino populations. Georgia, Virginia and Pennsylvania round out the top five.

Officials report that many recipients have not responded to outreach efforts. However, there are a number of reasons that an eligible consumer may not be responsive: certain eligible consumers may simply maintain poor record-keeping, the government could be faulted due to mix ups and/or errors, or the letter could have simply gotten lost in the mail. This can potentially result in a loss of insurance for the year, though officials have communicated that a majority of cases are decided in favor of enrollees.

Thirty-six states will be affected by the new policy, though it's unclear how the policy will apply to states such as New York and California, which run their own insurance exchanges.  

Letters began being sent out Tuesday, Aug. 12, 2014. However, the letters won't be the final attempt to reach consumers with unresolved issues. The Department of Health and Human Services reports that they will attempt to reach each consumer two times by phone, and once through email. Also, the Obama admiration will attempt to reach people directly in their homes.

Those with unresolved discrepancies regarding income will be sent notices at a later date as well. Also, notices pertaining to both matters will only affect this year's coverage.

Enrollment for 2014 has ended, and open enrollment season for 2015 will begin on Nov. 15, when insurance purchasers will be able to renew or make changes to their current coverage plans. Additionally, uninsured individuals, who are new to the marketplace, will be able to shop around for the plan that is right for them, securing mandated health insurance, or face a fine.    

Consumers with discrepancies are encouraged to contact the HealthCare.gov call center at 1-800-318-2596 to inquire about what documents are required and to check on whether their information has been received.
