High Turnover and the Coverage Cliff: What Happens to Workers Who Churn Through Level Funded

LFP-06.08 | Sharp Analysis | Series 06: The Populations

Industries with high employee turnover are structurally incompatible with the plan-year assumptions of level funded design. The plan year runs 12 months. The restaurant and hospitality industries turn over the majority of their workforces annually. Home health care runs annual turnover rates that frequently exceed 60%. The mathematics do not reconcile.

A worker employed for four months, covered for three of them after satisfying the waiting period, and then separated faces a coverage cliff. COBRA continuation coverage is available at full premium cost that most workers at this income level will not pay. The ACA marketplace is available, but enrollment is restricted to special enrollment periods that may not align with the timing of separation. The gap between coverage periods is where emergency department visits accumulate, prescriptions lapse, and chronic conditions progress untreated.

The workers who churn through level funded plans bear the cost of the incompatibility between the plan-year structure and the workforce reality. Both the employer and the plan register the enrollment and termination as administrative completions. Neither registers what happened to the worker in the months without coverage.

Turnover Rates in Level Funded Industries

#

The Bureau of Labor Statistics Job Openings and Labor Turnover Survey provides monthly separation rate data by industry. Converting monthly rates to annual approximations, the leisure and hospitality sector, which includes accommodation and food services, has shown total annual separation rates approaching 70% to 80% in recent years. The 2024 annual average total separations rate across all private industry was 3.3% per month, but leisure and hospitality runs at approximately double that rate. Health care and social assistance, while lower overall, includes the home health subsector where PHI National, the workforce research organization for direct care workers, documented turnover rates of 77% annually among home health aides nationally in 2021, driven by low wages, physical demands, and limited advancement pathways.

Seasonal industries show different patterns with the same structural result. Construction employment fluctuates with weather and project cycles. A worker hired in April may be laid off in November, rehired by a different contractor in March, and laid off again in October. Each new employment period resets the waiting period clock. The worker cycles through coverage eligibility and termination multiple times per year with no mechanism to carry coverage across the transitions.

Staffing agencies present a specific case. Staffing agencies are the employer of record for workers placed at client sites, and level funded adoption among staffing agencies is growing because the agency controls the group and can purchase coverage across placements. But workers in staffing arrangements have high turnover by design. When an assignment ends, employment terminates unless a replacement assignment is immediately available. The staffing model creates systematic coverage gaps as a structural feature, not an administrative failure.

The Waiting Period and the Coverage Window

#

The ACA limits waiting periods for group health coverage to 90 days. Most employers impose shorter periods. The KFF 2024 Employer Health Benefits Survey shows that among small employers, approximately 24% impose waiting periods of 30 days or less, 27% impose 31 to 60 days, and 15% impose 61 to 90 days.

The waiting period determines the coverage window for short-tenure workers. A worker employed for four months and subject to a 60-day waiting period has two months of coverage. The employer contributes to the claims fund for two months. The stop loss premium is paid for two months. The administrative cost of enrollment, ID card issuance, eligibility verification, and termination processing is incurred regardless of tenure length.

For high-turnover employers, the coverage window arithmetic changes plan economics. An employer with 60% annual turnover is not covering a stable population of 30 employees. The employer is covering a rotating population in which the majority of enrolled members at year-end were not enrolled at year-start. The claims fund is sized for expected claims from a stable population with predictable utilization patterns. A rotating population has different characteristics: more acute care from members without established primary care relationships, more deferred care from members who were not covered long enough to address preventive needs, and more administrative cost per claims-dollar from the enrollment and termination processing of high-churn membership.

The waiting period functions as adverse selection mitigation from the employer’s perspective: it ensures coverage attaches only to workers who have demonstrated some employment stability. The worker who is employed for 89 days and separated on day 90 was never covered.

The COBRA Cliff

#

COBRA continuation coverage is the statutory mechanism for maintaining group health coverage after employment separation. An employer with 20 or more employees in the prior calendar year is subject to federal COBRA. Smaller employers are subject to state mini-COBRA laws, with coverage periods and terms varying by jurisdiction.

Under COBRA, the separated employee may continue group coverage for up to 18 months by paying the full premium, both employer and employee shares combined, plus a 2% administrative fee. The KFF 2024 Employer Health Benefits Survey reports that the average total annual premium for employer-sponsored single coverage was $8,951 in 2024. For a worker previously contributing $150 to $200 per month as her employee share, COBRA premiums of $750 to $800 per month represent a fourfold increase in out-of-pocket cost. For family coverage, COBRA premiums can exceed $2,100 per month.

For workers earning $25,000 to $35,000 annually, COBRA is economically inaccessible. Monthly take-home pay for a worker earning $30,000 is approximately $2,100 after taxes. COBRA premiums of $750 per month for single coverage consume 36% of take-home pay. COBRA for family coverage would exceed take-home pay for most of this income range.

DOL data on COBRA elections confirms the pattern. Among eligible separated workers, election rates are substantially below 100%, with available estimates suggesting election rates of 20% to 25% in typical years, substantially lower among low-wage workers for whom the premium is economically prohibitive. The workers for whom COBRA was designed, those experiencing temporary job transition who need coverage continuity and can afford the premium, use it. The workers churning through level funded plans in high-turnover industries largely cannot.

The Gap and Its Consequences

#

The coverage gap between employment termination and the next coverage event produces measurable health consequences documented in the literature.

Emergency department utilization increases during coverage gaps. National Center for Health Statistics data shows that adults reporting a coverage gap in the prior 12 months have emergency department visit rates substantially higher than continuously covered adults. The mechanism is legible: when primary care is unaffordable or inaccessible without coverage, acute conditions accumulate and present at the emergency department when they can no longer be deferred.

Prescription medication adherence deteriorates during coverage gaps. A worker taking maintenance medications for hypertension, diabetes, or depression faces immediate out-of-pocket costs when coverage lapses. The cash price for branded or specialty medications can reach hundreds of dollars per month. Nonadherence during coverage gaps produces preventable hospitalizations and disease progression that are visible in the claims of the next plan that covers the worker.

Sommers and colleagues documented health consequences of coverage loss in research published in the Journal of General Internal Medicine examining Medicaid coverage disruptions. Adults who experienced Medicaid coverage losses showed higher rates of unmet medical needs, delayed care, and emergency department utilization in the months following coverage loss. The research examined Medicaid populations, but the physiological and economic mechanism of coverage loss applies to commercial coverage gaps as well: when coverage ends, care is deferred, and the consequences accumulate.

The cost of the coverage gap is not borne only by the worker. Emergency department uncompensated care shifts cost to the hospital system. Community health centers absorb increased demand. The next employer’s health plan absorbs the cost of conditions that progressed during the gap. The level funded plan that covered the worker for two months and then terminated the coverage has externalized those costs to systems outside the plan’s accounting.

The workers churning through high-turnover industries do not experience level funded as a coverage solution. They experience it as temporary access that disappears when employment ends, replaced by a gap they cannot afford to fill. The coverage exists for the months of employment. The gap is the structural feature.
