Coverage Protection Act of 2013 - Authorizes the Secretary of Health and Human Services (HHS), in the case of an individual who enrolls in a qualified health plan offered through a health care exchange established under the Patient Protection and Affordable Care Act (PPACA) before February 1, 2014, to require the issuer of the plan to treat such individual as enrolled as of December 23, 2013, if the individual:

• attests, not later than January 31, 2014, to making reasonable, good-faith attempts to successfully enroll in such a plan through an exchange before December 23, 2013, or was initially determined through an exchange to be eligible to enroll in a Medicaid plan but is not eligible to so enroll in such a plan and, because of the incorrect eligibility determination, was subsequently unable to enroll in a qualified plan before December 23, 2013; and
• pays, not later than January 31, 2014, the monthly premiums for the plan in which such individual enrolls for January and February 2014, taking into account the amount of any premium assistance made available under the Internal Revenue Code.

Counts coverage provided under a qualified plan for January and February 2014 under this Act as coverage under such a plan by or through an exchange for such months for all purposes, including premium assistance, PPACA cost-sharing reductions, and the requirement to maintain minimum essential coverage.

Directs the Secretary to require a health insurance issuer that offers a qualified plan through an exchange to:

• allow in-network providers in the plan to treat a receipt of payment of premiums by an individual enrolled for January or February 2014 who has not received a health insurance card from the issuer in the same manner as if such receipt were such a health insurance card issued for services furnished during such month; and
• notify such in-network providers of that policy.
