Mississippi Level-Funded Market at a Glance
Level-Funded Health Insurance in Mississippi: What Employers Need to Know
Mississippi has among the lowest health insurance costs in the nation, with a cost index of 0.80 reflecting costs that are 20% below the national average. This creates a favorable foundation for level-funded plans, as the lower baseline claims reduce the risk component of the arrangement. However, Mississippi also has higher-than-average chronic disease prevalence, which can affect claims experience for individual employer groups.
The level-funded market in Mississippi is more limited than in larger states, with Blue Cross Blue Shield of Mississippi dominating the fully insured market and national carriers providing the primary level-funded alternatives. UnitedHealthcare and Cigna have the strongest level-funded presence, while Aetna also offers products in the state. The limited carrier competition means Mississippi employers may need to be more diligent in comparing terms.
Mississippi has not expanded Medicaid and has minimal state-specific benefit mandates, keeping both fully insured and level-funded plan costs relatively low. The state's smaller employer base and lower population density mean fewer carriers see Mississippi as a primary market, but the low cost environment and minimal regulatory burden make it an attractive location for level-funded arrangements when carriers do participate.

Calculation Methodology
Fully Insured Cost: Current PEPM x number of employees x 12 months. Projected forward using the annual renewal increase rate.
Level-Funded Breakdown:
- Claims Fund: PEPM x claims ratio x state cost index (0.8 for Mississippi) x age factor x industry adjustment x plan tier multiplier. This is held in a claims account to pay medical expenses.
- Admin Fee: PEPM x admin percentage. Covers TPA fees, network access, compliance, and reporting.
- Stop-Loss Premium: Based on attachment point selected. Adjusted by Mississippi's stop-loss factor (0.88) and group demographics.
- Total Level-Funded: Claims Fund + Admin Fee + Stop-Loss Premium.
Scenario Modeling:
- Best Case: Actual claims at 55% of expected. Employer receives ~50% of surplus (unused claims fund) as a refund.
- Expected Case: Actual claims match the expected claims fund. Typical savings vs fully insured.
- Worst Case: Claims run 130% of expected, but stop-loss caps total exposure at 125% of expected claims fund.
State Cost Index: Mississippi's index of 0.8 adjusts base claims for state-level provider costs, utilization patterns, and regulatory environment. Based on CMS Geographic Practice Cost Index and Mississippi DOI rate filings.
Data Sources: SOA Group Health Experience Study, Mercer National Survey 2025, KFF 2025 Employer Health Benefits Survey, TrustMark/Voya level-funded reference data, Sun Life stop-loss rate manuals, NAIC stop-loss model regulations, CMS Federal Age Rating Curves, Mississippi Department of Insurance filings.
Analyst Notes: Mississippi Level-Funded Market
Actuarial Context: Mississippi's cost index of 0.8 reflects the state's position relative to the national average for employer-sponsored health insurance. The level-funded discount potential of 14% is achievable for groups with favorable demographics, but actuarial credibility requires sufficient enrollment -- typically 2+ employees for most carriers in Mississippi. Groups below this threshold face wider confidence intervals in claims projections, which carriers compensate for through higher stop-loss premiums and reduced surplus return percentages.
Methodology Disclosure: This calculator uses a simplified actuarial model that applies age factors (CMS 3:1 curve), industry adjustments (SOA experience studies), and state-specific cost indices (CMS GPCI) to the user's inputs. The stop-loss pricing is based on reference rate schedules from major reinsurers, adjusted by Mississippi's stop-loss factor of 0.88. Actual carrier quotes will incorporate additional underwriting factors including census-level age/gender distribution, prior claims experience, SIC code, plan design details, and network selection.
Risk Assessment: The limited carrier market in Mississippi provides limited competitive dynamics for level-funded pricing. Limited carrier competition but low baseline costs offset concern. Employers should request quotes from at least 2-3 carriers to ensure competitive terms on admin fees, stop-loss pricing, and surplus return provisions.
