Group Health Insurance for Mid-Size Texas Employers (50–500 Employees)

Once a Texas employer passes 50 employees, group health insurance stops working the way it did at 20. The ACA employer mandate applies at 50 full-time-equivalent employees, Texas moves you out of small-group rating at 51, your own claims experience starts driving your renewal, and level-funded and self-funded plans become realistic options next to fully insured. This guide covers what changes, which funding option fits which group, and how to get the claims data you are entitled to under Texas law.

It is written for employers in the 50-to-500 range in Texas and Oklahoma who already have a plan and want to buy it better. If you are buying a first plan, start with our guide to group health insurance for small business in Texas instead.

What Changes at 50 Employees

Fifty employees is a legal line, not just a size milestone. Cross it and four things change at once:

• You become an Applicable Large Employer (ALE). The ACA’s employer mandate applies: you must offer affordable, minimum-value coverage to full-time staff, and file Forms 1094-C and 1095-C with the IRS each year. The IRS counts full-time equivalents from the prior calendar year, so part-time hours count toward the 50. The affordability and penalty figures change by plan year; see our ACA compliance guide for the current numbers.
• You leave small-group rating. The Texas Department of Insurance defines a small employer as 2 to 50 employees, rated on a standard formula that cannot be raised for your employees’ health. At 51 and up, carriers underwrite your group on its own demographics and claims history, which cuts both ways but opens real room to negotiate if your group is healthy. The two lines do not quite match: the ACA counts full-time equivalents from 50, Texas counts employees from 51, so a company with exactly 50 can be an ALE and still be rated as a small group.
• More funding options open up. Level-funded and self-funded plans with stop-loss coverage move from theoretical to realistic. See our breakdown of level-funded vs. self-funded plans.
• Renewals start running on data, not guesswork. A mid-market employer should be reviewing its own claims experience, not just a renewal letter, and starting that review months ahead of the plan’s effective date.

Medcore focuses on employers with 50 or more employees in Texas and Oklahoma, and works with smaller groups on the way there.

Fully Insured vs. Level-Funded at 50-500 Employees

Every group at this size can still stay fully insured: predictable premiums, no claims exposure, simplest to administer. What changes is that it stops being the default. At 50 and up, your broker should quote at least one funding alternative alongside the fully insured renewal every year, not just forward the incumbent carrier’s number.

Funding type	How it works	Where it tends to fit at 50-500 employees
Fully insured	Carrier sets a fixed premium and carries all claims risk.	Groups that want budget certainty or don’t yet have stable claims history.
Level-funded	Employer pays a fixed monthly amount covering expected claims, admin, and stop-loss; often reconciled with a refund if claims run low.	Groups with reasonably predictable claims that want a path toward self-funding without taking on full risk.
Self-funded with stop-loss	Employer pays actual claims directly, with a stop-loss policy capping exposure above a set threshold.	Larger, more stable groups with enough claims volume and a comfortable risk appetite.

When Self-Funding Becomes Realistic

There is no single headcount where self-funding switches on. What matters is whether your claims experience is stable enough, and your group large enough, that a bad year does not threaten the budget once stop-loss coverage is in place. A few signals that it is worth modeling:

• You have had at least two to three years of consistent enrollment and claims history with the same carrier or TPA.
• Your group has not had a single catastrophic claim that skews the average well above your market.
• Leadership is comfortable with month-to-month claims variability in exchange for the upside when a year runs light.
• You have, or are willing to get, the reporting in place to track claims against budget throughout the year.

If those hold, level-funded and self-funded quotes are worth running side by side with your fully insured renewal, with real numbers rather than a theoretical savings projection.

Getting Access to Your Own Claims Data

This is the piece that is easiest to skip and most expensive to skip. Below 50, your rate comes from a pooled formula, so your own claims barely move it and few small employers ever ask for them. At 50-plus, your claims experience increasingly sets your rate, and the report is yours to request.

If your plan is fully insured, Chapter 1215 of the Texas Insurance Code requires your carrier to deliver a written claims report within 30 days of a written request. The report covers up to the previous 36 months and must include:

• Paid claims by month, split into medical, dental and pharmacy
• Premiums paid by month
• Covered employees by month and coverage tier
• Total claims pending on the date of the report
• Claim detail for any individual whose paid claims exceeded $15,000 in the prior 12 months (identifying detail is released only after the plan sponsor signs a HIPAA certification)

The carrier only has to produce it twice in any 12-month period, and the statute has no employer-size threshold, so an insured group of 20 can ask as well. If you are level-funded or self-funded, the reporting comes from your administrative agreement rather than the statute; ask your carrier or TPA what it provides and how often. See the claims experience report FAQs for the request itself.

Ask for the claims and large-claims report well before renewal, not during it.

What a Mid-Market Service Model Looks Like

Account management at this size should look different from a small-group relationship: a renewal process that starts months ahead rather than weeks, ACA reporting handled as part of the service rather than billed as an add-on, help structuring group life, disability and critical illness lines you will need to compete for talent, and carrier knowledge in the metros where your people actually are, since network strength varies between Dallas, Houston, Fort Worth and San Antonio.

Mid-Size Group Health Insurance: Frequently Asked Questions

Is 50 employees a large group in Texas?

Not quite. Texas defines a small employer as 2 to 50 employees, so large-group underwriting starts at 51. The ACA employer mandate, however, starts at 50 full-time equivalents. A company with exactly 50 can be an Applicable Large Employer under the ACA and still be rated as a small group by Texas carriers.

How do I get our claims experience report from the carrier?

Send the carrier a written request. For a fully insured plan, Texas Insurance Code Chapter 1215 gives it 30 days to deliver a written report covering up to 36 months of paid claims, premiums, enrollment by tier, pending claims, and detail on anyone over $15,000 in paid claims in the prior 12 months. You can request it up to twice in any 12-month period.

What is the difference between level-funded and self-funded?

Both put you on the hook for your own claims up to a limit, with stop-loss above it. In a level-funded plan the carrier bundles expected claims, administration and stop-loss into one fixed monthly payment and settles up at year end, so cash flow looks like a fully insured premium. In a self-funded plan you pay claims as they occur through a TPA, so costs vary month to month but you keep every dollar of a good year.

Does a 50-employee group need stop-loss insurance?

Only if the plan is level-funded or self-funded. A fully insured carrier already carries the claims risk. For a funded plan, specific stop-loss caps what you pay for any one person’s claims and aggregate stop-loss caps total claims for the year; at 50 to 100 employees most groups need both.

Do mid-size employers get better rates than small groups?

Not automatically. Leaving small-group rating means your own demographics and claims history set your price, which rewards a healthy group with stable claims and penalizes one with a bad year. The advantage at this size is leverage: you can take your claims data to market and negotiate, which a pooled small group cannot.
