CareSource vs. UHC: What Types of Plans Do They Offer?

CareSource offers several different types of insurance plans:

  • Individual health insurance on the Marketplace, sometimes referred to as Obamacare 
  • A Medicare Advantage HMO plan, a Medicare Advantage Dual-eligible Special Needs Plan (D-SNP) and a Medicare-Medicaid plan available only in select counties in Ohio. 

UHC offers a wide variety of insurance plans including Medicare Advantage, Medicare Part D, Medicare Supplement Insurance, Medicare-Medicaid plans, supplemental standalone plans such as dental and vision packages and health insurance plans for both groups and individuals. 

CareSource vs. UHC: Plan Reviews and Star Ratings

Both CareSource and UHC maintain A+ ratings with the Better Business Bureau. However, UHC maintains high ratings of its own with an AA- rating with Fitch Ratings, an A1 rating with Moody’s and an A ratings with AM Best.  

Each year, the Centers for Medicare and Medicaid Services (CMS) rates the quality of each carrier’s Medicare plans. A licensed insurance agent can help you compare Star Ratings for plans where you live, or you can compare your local plan options online.

Is a CareSource or UnitedHealthcare Medicare Plan Right for You?

UHC is a large company that serves customers all over the U.S. with a wide variety of high-quality plans. CareSource has a more limited service area in which its plans are offered, meaning that residents of only a few states are able to apply for a CareSource plan. 

But deciding which carrier to do business with is often less about which company is considered the best and more about which carrier more directly addresses your needs. CareSource may be a good option for you if you live where CareSource Medicare plans are available, particularly if you qualify for Medicaid benefits. UHC may be for you if you live outside the CareSource service area or if you’re looking for a wider variety of plan selection. 

You can compare Medicare Advantage plans available where you live, including D-SNP plans if any are available, by searching for plans online. You can also call to speak with a licensed insurance agent who can help you compare plans and enroll in one that meets your needs.
