At 11.0% uninsured among under-65 residents — the 3rd lowest of the 254 counties in Texas — Collin County is among the best-covered parts of Texas, well below the state's 19.1%. Only about 120,068 people here have no coverage. That is good news with one edge to it: near-universal employer coverage means very little local familiarity with the individual market when a job ends.

What you can actually buy here
10 insurers sell into Collin County — among the most competitive individual markets in the country. That much competition holds premiums down, and it produces a plan list long enough that choosing at random is a genuine risk. Narrowing by hospital system first is the only reliable way through it. Between them they offer 127 plans, about 13 for each insurer, which is a normal-sized list to work through once you know which network you need. The count is unchanged from last year, so the networks you compared previously still stand.
168,207 marketplace plan selections were recorded in Collin County for 2026, or 154 per thousand under-65 residents — above the 127 typical of the counties covered here. Enough people locally have done this that the process is not unfamiliar territory. Of those, 46,619 were new to the marketplace and 121,588 were renewing. A 28% new share is high, and new enrollees are disproportionately people who lost job-based coverage during the year rather than people shopping by choice.
