COLUMBIA — An insurance company said it's leaving South Carolina because of regulations related to health care reform.

Medical Mutual of Ohio is the parent company of the Carolina Care health plan, which covers 28,000 policyholders in South Carolina.

Medical Mutual spokesman Ed Byers said on Friday the company plans to pull out of South Carolina by the end of the year to focus on its home market of Ohio, where it covers 1.6 million members.

Byers said changes under the federal health care act that go into effect this year and next year played into the company's decision to leave South Carolina.

He said policyholders covered under Carolina Care are being transitioned to UnitedHealthcare.

Sen. Lindsey Graham, R-S.C., said, “I hate to say I told you so, but I told you so. Every day we see stories like this about Obamacare – rising prices, fewer choices, and more confusion for patients and providers. We now have one less choice for health insurance in South Carolina. In the days to follow, people will likely lose their choice of doctor as well. Unfortunately, this is just the beginning of the disaster that will befall our country if Obamacare is fully implemented.”
