What Interactive Medical Systems does

Interactive Medical Systems (IMS), founded in 1981 and headquartered in Wake Forest, North Carolina, is a privately held third-party administrator (TPA) that processes and administers self-funded employee benefit plans for mid-market and large U.S. employers. The company's six core service lines are self-funded medical plan administration, self-funded dental plan administration, Flexible Spending Accounts (FSA), Health Savings Accounts (HSA), Health Reimbursement Accounts (HRA), and COBRA administration (which also extends to retiree billing, direct billing, and leave-of-absence billing). The company is independently owned and operated with no carrier affiliation, and it sells through a combination of direct employer outreach and an insurance broker/consultant channel that serves as its primary acquisition motion.

The technology stack is anchored by proprietary member-facing tools including the IMS Flex WealthCare Portal and the IMS Flex Mobile Application (iOS and Android), which provide balance viewing, transaction tracking, claims management, online HSA employer payroll contributions, and online balance transfers. Consumer account administration is supported by benefits debit cards with Inventory Information Approval System (IIAS) and Merchant Category Code (MCC) technology for automatic eligibility verification at point of sale. IMS integrates with multiple HSA custodians (Avidia Bank, WealthCare Saver, HSA Bank), national dental PPO networks (DenteMax, CIGNA Dental Network, NovaNet), consumer storefronts (FSA Store, HSA Store), and the Employee Navigator benefits administration marketplace. Add-on modules include stop-loss coverage coordination, pharmacy benefits, care management, cafeteria plan / Section 125 POP administration, and Summary Plan Document preparation.

Revenue is generated through managed-services TPA fees negotiated per client based on employee count, plan type, and scope of services, with annual billing cycles. Pricing is custom and not publicly disclosed. The company employs 11-50 staff led by CEO Eric Ludwig (with the organization since the 1980s/1990s) and COO Brent Monroe, and operates a single U.S. office. Compliance coverage spans ERISA, HIPAA, COBRA, and PPACA, and the company supports both new plan implementations and ongoing renewals, vendor coordination, and stop-loss placement.
