Antum Risk

What Antum Risk does

Antum Risk is a Columbia, South Carolina-based healthcare risk management firm that operates three group self-insurance programs — workers' compensation (Palmetto Hospital Trust, founded 1977), professional and general liability (PHLIP, founded 2001), and medical stop-loss (PHSLP, founded 2011) — alongside consulting, physician practice risk assessments, and OSHA training services. The company is structured as a member-owned captive, meaning the healthcare organizations it serves participate in governance and share in surplus returns, aligning incentives and creating a distinct alternative to commercial insurance for South Carolina hospitals, health systems, and physician practices. Underlying technology consists of proprietary risk assessment processes, specialized audit tools developed for healthcare settings, a Physician Practice Toolkit of best practices and sample policies, and a client portal that supports electronic claims reporting for both workers' compensation and professional liability lines.

The business model combines recurring premium revenue from the three captive programs, fee-based consulting and risk management services, and unit-priced training programs (e.g., OSHA 10-Hour at $200, OSHA 30-Hour at $600 for non-members). Pricing is largely quote-based and not publicly disclosed for insurance and consulting engagements. The company employs 11-50 staff and sells primarily through direct enterprise relationships with healthcare organizations in South Carolina, while the PHSLP stop-loss program has been extended nationally to self-insured employers in most U.S. states. Named anchor customers include AnMed Health, McLeod Health, Self Regional Healthcare, Conway Medical Center, and Anderson County, with documented member outcomes including $5.3M in savings for Self Regional Healthcare over nine years and 50%+ stop-loss savings for Anderson County in year one. Marketing and member education are driven through a content ecosystem spanning a blog, podcast series, webinars, and in-person training events.
