Overview

Sun Life U.S. stop-loss is the medical excess-risk product of Sun Life Assurance Company of Canada (Wellesley Hills, MA) in most states and Sun Life and Health Insurance Company (U.S.) (Lansing, MI) in New York (policy form series 07-SL REV 7-12 / 22-SL and New York 07-NYSL / 22-NYSL). The employer stop-loss page says Sun Life has offered stop-loss more than 40 years, is the largest independent stop-loss provider, covers over 6 million members, and has $3.0 billion of in-force premium. Offerings named include traditional stop-loss, comprehensive health solutions, and captive arrangements. Stop-loss is not approved for use in New Mexico; availability varies by state.
