Why your county matters for coverage
In Texas, the health plans you can choose depend on where you live. Medicare Advantage and Part D plans are offered by service area, usually county by county, and marketplace premiums and carriers are set by area as well. Living in Collin County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: Texas HICAP (Health Information, Counseling and Advocacy Program) gives free, unbiased counseling at 800-252-9240. Ask which plans serve Collin County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Collin County ZIP code to see what is offered.
- Medicaid: apply through Texas Health and Human Services Commission (HHSC).
Texas note: Texas has not expanded Medicaid to all low-income adults, so Texas Medicaid eligibility rules can differ meaningfully from states that did expand -- worth confirming directly with HHSC or by phone rather than assuming another state's rules apply.
