Which Insurers Are Leaving Oklahoma’s Marketplace in 2027?

Published August 28, 2026 · Daniel Griffin, Licensed Independent Advisor · NPN #22052447

Two insurers stop selling individual marketplace plans in Oklahoma on January 1, 2027 — Medica and Mending. Medica’s exit alone affects about 8,400 Oklahomans.

Oklahoma had seven marketplace carriers last year. Losing two in a single cycle is a bigger proportional hit than most states are taking, and it is happening for a reason that is about to show up on your own premium.

Oklahoma Is Losing Two Insurers, Not One

Most of the 2027 exit coverage has been about Cigna. Cigna is not leaving Oklahoma — it is not one of the eleven states in that announcement. Oklahoma’s problem is a different one, and it is arguably worse: two separate insurers are leaving at once.

• Medica stops offering individual marketplace plans in Oklahoma on January 1, 2027, affecting roughly 8,400 members. Medica is also leaving Iowa and Kansas in the same move.
• Mending announced its Oklahoma exit first. Its co-founder pointed to rising health costs and the expiration of the enhanced premium tax credits as the reasons.

Oklahoma had seven carriers on the marketplace last year. Losing two of them in one cycle thins the field enough that plan comparison actually matters this year, particularly outside the Oklahoma City and Tulsa metros.

Why the Second Reason Matters More Than the First

Mending naming the enhanced-credit expiry is worth sitting with, because it is the same thing that is about to hit your own premium. The enhanced subsidy schedule expired on 31 December 2025. For 2026 and 2027 the credit cuts off completely above 400% of the federal poverty level — about $62,600 for a single filer — with no taper. One dollar over the line and the entire credit disappears.

When enough healthy, unsubsidised people respond to that by dropping coverage, the risk pool gets sicker and insurers leave. That is the mechanism playing out in Oklahoma right now. Check where you fall against the cliff →

What Happens to Your Plan Automatically

Your current Medica or Mending plan runs through 31 December 2026. You are not dropped mid-year. At open enrollment the exchange will try to auto-enrol you into a plan from a remaining carrier — and that is the part to watch. Auto-enrolment matches on metal tier and price, not on your doctors or your prescriptions. People who let it happen routinely discover in February that their specialist is out of network.

If you are on a Medica or Mending plan in Oklahoma, treat this open enrollment as an active decision, not a renewal.

What To Do in Oklahoma

1. Confirm who your carrier is. It is on your ID card, not always the name you remember signing up with.
2. List your doctors and drugs before you shop, then check them against the remaining carriers rather than the other way round.
3. Re-run your subsidy. Your 2027 income estimate, not your 2025 one, decides your credit — and the cliff is unforgiving.
4. Do not auto-renew. With two carriers gone, last year’s equivalent plan may not exist.

If You Are Above the Subsidy Line, This Is a Different Decision

Most advice about a carrier leaving assumes you have a premium tax credit softening the replacement. If your household is above 400% of the federal poverty level — about $62,600 for one person, $84,600 for a couple and $128,600 for a family of four in 2026 — you do not. You pay the full filed price of whatever you move to, and the enhanced rules that used to cap that at 8.5% of income expired on 31 December 2025.

That changes what you are choosing between. With a credit, moving to a pricier replacement costs you comparatively little, because the credit absorbs most of the difference. Without one, every dollar of the increase is yours.

So before you pick a replacement, do two things in this order:

1. Confirm you are actually above the line. The test is modified adjusted gross income, not revenue, and a retirement or HSA contribution can move a household back under it. How the cliff arithmetic works →
2. If you are clearly above it, price both markets. Marketplace plans charge everyone your age the same regardless of health. If you are healthy and getting no credit, that pooling is costing you something and returning nothing. Your options above the cliff →

If anyone in your household has a meaningful health history, stay on the marketplace — guaranteed issue is exactly what you are paying for, and it is worth it. Why premiums jumped this year →
