Open enrollment impact on clinic revenue (2026)
Open enrollment reshuffles your payer mix every year. Some changes help you. Others erode revenue quietly. Here is what to watch and how to prepare.
How enrollment changes affect your payer mix
Every November through January, your patients make insurance decisions that directly affect your revenue. Patients switching plans can change your payer mix without your practice doing anything differently. A single large employer in your area changing their health plan can shift 5-10% of your patient volume to a different payer.
The financial impact depends on which direction the shift goes. Patients moving from a plan where you are in-network to one where you are not may stop coming entirely. Patients moving from a high-reimbursement commercial plan to a lower-reimbursement MA plan reduce your per-visit revenue.
Patient volume shifts to expect
January through March typically sees a volume spike as patients with new insurance seek care. Patients with new plans often schedule appointments they deferred, especially if they switched to a plan with lower deductibles.
Conversely, patients who lose coverage or gain high-deductible plans may defer care. Track no-show rates and new patient volume separately in Q1 to identify which trend is dominant in your practice.
Copay and deductible changes
When patients change plans, their copay and deductible structures change. High-deductible health plans (HDHPs) continue to grow in market share, which means more patients owe larger amounts out of pocket before insurance pays anything.
Your front desk collection process matters more when deductibles are high. If you are not collecting copays and estimated patient responsibility at the time of service, your patient AR will spike in Q1. Implement or tighten your point-of-service collection policy before January.
- Verify insurance eligibility for all patients at the start of the year, not just new patients
- Update copay and deductible information in your system for returning patients
- Train front desk staff on collecting estimated patient responsibility upfront
- Consider offering payment plans for patients with high deductibles
Credentialing for new plans
If a significant number of patients switch to a plan you are not credentialed with, you either lose those patients or need to get credentialed quickly. Credentialing typically takes 60-120 days, so acting in November when open enrollment starts is already late for January.
Review the plans offered by the top employers in your service area. If any major employer is switching to a plan you do not participate in, start the credentialing process immediately. Losing 50 patients because of a credentialing gap is a $50,000-$150,000 annual revenue loss depending on specialty.
Marketplace and Medicaid enrollment trends
ACA marketplace enrollment has grown significantly, and the expanded subsidies affect which plans patients choose. If your practice sees marketplace patients, understand which silver and gold plans dominate in your market and ensure you are in-network.
Medicaid redeterminations continue to affect patient eligibility. Patients who lose Medicaid coverage may gain marketplace coverage or become uninsured. Track the conversion patterns in your patient population.
What to do now
Identify the top 5 employers in your service area and research their 2027 health plan offerings.
Check your credentialing status with any new plans being offered by major local employers.
Implement or tighten point-of-service collection policies for copays and estimated patient responsibility.
Set up an insurance verification process that runs for all patients in the first two weeks of January.
Track new patient volume and payer mix weekly through Q1 2027 to catch shifts early.
