Short Term Health Insurance vs. COBRA

COBRA keeps your exact comprehensive plan at full price; a short term plan costs less but is underwritten, limited and temporary. The side by side and four questions that decide it.

When you leave a job, two temporary options often come up: continuing your old employer plan through COBRA, or buying a short term health plan. They solve the same timing problem, a coverage gap, in very different ways, and one of them keeps the comprehensive coverage you already had.

Bottom line up front: COBRA lets you keep your exact employer plan for a limited time, it's comprehensive and counts as minimum essential coverage, but you typically pay the full cost yourself. A short term plan is cheaper-looking but temporary, medically underwritten, non-comprehensive, and not minimum essential coverage. If you have any health needs, COBRA (or an ACA marketplace plan) is usually the safer choice.

COBRA specifics, how long it lasts and exactly what you pay, depend on your employer and plan. Confirm the details with your HR department or plan administrator.

When a short term plan can make sense

Short term coverage is a niche bridge, not a default. It can be reasonable when all of these are true:

  • Your gap is short and clearly defined, you know when new coverage begins.
  • You're generally healthy, with no ongoing treatment or prescriptions you can't pause.
  • You can't enroll in a marketplace plan right now and don't qualify for a Special Enrollment Period.
  • You accept it won't cover preexisting conditions or the essential health benefits, and it isn't minimum essential coverage.

Duration limits are set by your state, so confirm what applies where you live before buying.

When COBRA is the better choice

COBRA tends to win when continuity and comprehensiveness matter:

  • You have a preexisting condition, take prescriptions, or are mid-treatment, COBRA keeps the same plan and network with no new underwriting.
  • You want to stay with your current doctors and avoid restarting deductibles by keeping the same plan year.
  • You value comprehensive coverage and minimum essential coverage status during the gap.
  • Losing job based coverage may also open a Special Enrollment Period for an ACA marketplace plan, worth comparing, since subsidies can make comprehensive coverage more affordable than it first appears.

How to decide in four questions

  1. 1How long is your gap, really? A short, certain gap may suit short term coverage; an open-ended or longer gap favors keeping comprehensive coverage.
  2. 2What's your health like? Any conditions or ongoing care strongly favor COBRA or a marketplace plan, which can't exclude preexisting conditions.
  3. 3Did you just lose job based coverage? That's a qualifying life event, check the ACA marketplace, where subsidies may beat COBRA on cost.
  4. 4Do you need minimum essential coverage? Only COBRA and comprehensive plans provide it; a short term plan does not.

Common mistakes to avoid

  • Choosing short term while mid-treatment. It's underwritten and typically excludes preexisting conditions, a bad fit if you're already receiving care.
  • Skipping the marketplace comparison. Losing coverage usually opens a Special Enrollment Period; a subsidized ACA plan may cost less than both alternatives.
  • Assuming COBRA numbers. How long it lasts and what you pay depend on your employer and plan, confirm with HR rather than guessing.
  • Treating short term as equivalent to your old plan. It isn't comprehensive and isn't minimum essential coverage.

Key takeaways

  • COBRA continues your exact employer plan, comprehensive and minimum essential coverage, but you typically pay the full cost; specifics depend on your plan.
  • Short term coverage is temporary, underwritten, non-comprehensive, and not minimum essential coverage.
  • Losing job based coverage usually opens a Special Enrollment Period, so compare a subsidized ACA plan before deciding.
