Health Care Choice Act of 2013 - Repeals the health insurance and health coverage expansion requirements of the Patient Protection and Affordable Care Act and related requirements of the Health Care and Education Reconciliation Act of 2010. Restores provisions of law amended or repealed by such provisions. Amends the Public Health Service Act to provide that the laws of the state designated by a health insurance issuer (primary state) shall apply to individual health insurance coverage offered by that issuer in the primary state and in any other state (secondary state), but only if the coverage and issuer comply with the conditions of this Act. Exempts issuers from any secondary state's laws that would prohibit or regulate the operation of the issuer in such state, subject to certain restrictions imposed by such state. Specifies the notice that an issuer must provide in any insurance coverage offered in a secondary state and at renewal of the policy. Requires each issuer issuing individual health insurance coverage in both primary and secondary states to submit to the insurance commissioners of such states: (1) a copy of the plan of operation or feasibility study, (2) written notice of any change in its designation of its primary state and of its compliance with all the laws of the primary state, and (3) a quarterly financial statement. Prohibits an issuer from offering, selling, or issuing individual health insurance coverage in a secondary state if the state insurance commissioner does not use a risk-based capital formula for the determination of capital and surplus requirements for all issuers. Gives sole jurisdiction to the primary state to enforce the primary state's covered laws in the primary state and any secondary state. Requires the Comptroller General to study the effect of this Act on specified health insurance issues.
