What Are Your Health Insurance Options as a Plumbing Business in Centralia?

Small businesses in Centralia, particularly those in the plumbing industry, have several pathways to providing health insurance. Your options will largely depend on the size of your workforce and your budget.

Small Group Health Plans: These are traditional employer-sponsored plans for businesses with 1-50 full-time equivalent employees. They offer a range of benefits, and employers typically contribute a portion of the premiums. These plans are available both on and off the GetCoveredIllinois marketplace.
Individual Marketplace Plans (ACA): If your business is very small, or if employees prefer to choose their own plans, individual plans through GetCoveredIllinois are an option. Eligible individuals may qualify for premium tax credits and cost-sharing reductions based on household income.
Health Reimbursement Arrangements (HRAs): HRAs, such as the Qualified Small Employer HRA (QSEHRA) or Individual Coverage HRA (ICHRA), allow employers to reimburse employees for health insurance premiums and medical expenses tax-free. This provides flexibility while allowing employees to choose individual plans.

Understanding the nuances of each option is key to selecting the best fit for your Centralia-based plumbing company and its employees.

Eligibility and Requirements for Small Business Plans in Illinois

To offer a small group health plan, your plumbing business in Centralia must meet specific criteria, primarily related to employee count and participation.

Typically, to qualify for a small group plan, you need at least one full-time equivalent employee who is not the owner or a spouse. The Affordable Care Act (ACA) defines small businesses as those with 1 to 50 full-time equivalent employees. In Illinois, small group plans are guaranteed issue, meaning carriers cannot deny coverage based on health status.

Many carriers also require a minimum participation rate, often around 70% of eligible employees, to enroll in a group plan. This helps ensure a balanced risk pool for the insurer. For example, if you have 10 eligible employees, at least 7 would need to enroll in the plan. Employees who have other coverage (like a spouse's plan or Medicare) are usually waived from this calculation.

For individual plans, employees would apply through GetCoveredIllinois, and eligibility for subsidies depends on their household income relative to the Federal Poverty Level (FPL). For 2026, individuals with income between 100% and 400% FPL may qualify for premium tax credits. Illinois expanded Medicaid in 2014, so adults up to 138% FPL may qualify for Illinois Medicaid instead of marketplace subsidies.

Understanding Plan Types and Coverage in Centralia's Rating Area 9

Health insurance plans in Centralia, located in Illinois Rating Area 9, come in various structures, each with different network rules and cost-sharing models.

This is a significant advantage, as PPO plans ARE available on-exchange in Illinois, offered by carriers like Blue Cross and Blue Shield of Illinois, providing more choice and flexibility compared to some other states.

EPOs are similar but usually don't require PCP referrals, though you must stay within the network for covered care. PPOs offer the most flexibility, allowing you to see out-of-network providers (at a higher cost) without a referral, making them a popular choice for those who value broader access.
