How a Large Healthcare Employer Saved $2.9M with Dependent Eligibility Verification
Rising healthcare costs are a constant concern for employers, but few recognize how much of that spend is driven by ineligible dependents. Dependent eligibility issues are one of the most overlooked sources of waste in healthcare benefit plans as they quietly drive up costs, create compliance risks, and burden both members and employers.
Business Situation
A healthcare organization with over 5,200 employee families and 11,000+ dependents contracted with BMI Audit Services to conduct a Dependent Eligibility Verification Audit. The goal was to determine whether all enrolled dependents met the eligibility criteria outlined in the organization’s Summary Plan Descriptions (SPDs). With limited prior verification efforts, the employer recognized the need to validate eligibility ahead of the upcoming open enrollment cycle to reduce unnecessary claims and protect overall plan integrity.
The Solution: A Comprehensive Dependent Eligibility Verification Audit
To solve this problem, BMI implemented a comprehensive dependent verification plan, customized to the client’s health plan documents and enrollment data. The strategy included:
100% audit of all dependents using Summary Plan Description (SPD) guidelines as the source of truth
Secure collection and review of verification documentation such as birth certificates and marriage certificates
A bilingual call center offering live support
Ongoing communication campaigns to drive a 98%+ response rate
Daily reporting via a secure, password-protected web portal
Audit Findings
The audit uncovered 338 confirmed ineligible dependents and an additional 431 unverified dependents due to incomplete documentation or no response, totaling 769 dependents, nearly 7% of all dependents reviewed during the audit.
Using an estimated cost of $3,812 per dependent annually, the results were significant, with total projected savings of $2.93 million in the first year alone.
Among those confirmed as ineligible:
38.5% were voluntarily removed by employees
57.1% were eligible for group medical coverage through their own employer but had not enrolled
1.8% were divorced spouses no longer eligible under plan terms
2.7% were classified as other ineligible relationships reported by employees
These findings highlight the importance of ongoing verification reviews to reduce exposure, ensure compliance with plan definitions, and safeguard benefit spend.
The Results: $2.9M in First-Year Savings = Nearly 3,000% ROI
With an average annual cost of $3,812 per dependent, the healthcare employer identified nearly $2.93 million in potential annual savings by removing ineligible dependents.
Estimated First-Year Savings: $2,931,428
ROI: 2,887.91%
This outcome wasn’t just about recovering costs, it reflected a strategic investment in benefit accuracy, operational efficiency, and long-term plan sustainability. By acting early, the employer reduced financial exposure and set a plan for more responsible, compliant administration.
Conclusion
In today’s healthcare landscape, Dependent Eligibility Verification isn’t just a compliance box to check; it’s a strategic decision.
This audit reinforced the value of Ongoing Verification in maintaining benefit integrity and reducing plan spend. The process allowed the client to identify ineligible dependents, improve documentation requirements, and establish stronger internal controls moving forward.
As benefits teams prepare for future enrollment periods, this healthcare employer’s success demonstrates that dependent audits are not just about cost recovery; they are a practical, high-impact strategy for better plan management.
Whether you’ve never conducted a verification or it’s been several years, a structured audit process offers both immediate value and long-term clarity.
