Hawaii Medical Service Association

The Hawaii Medical Service Association (HMSA) is a health plan headquartered on Oahu with centers statewide. It describes itself as the most experienced health plan in Hawaii, covering more than half of the state's population, and is an independent licensee of the Blue Cross and Blue Shield Association. HMSA works with employers, partners, physicians, and other health care providers to promote wellness, develop reliable and affordable health plans, and support members with guidance. Its stated vision is a Hawaii where families and communities enjoy ever-healthier lives, and its purpose is to improve the lives of its members and the health of Hawaii.

HMSA's own history page describes its activities across the 2020s. It states that HMSA supported the community in times of need, particularly in response to the devastating Maui wildfires and the COVID-19 pandemic. Its Maui Wildfire Taskforce coordinated support for the Maui community through member outreach and care coordination as well as premium deferrals for affected employers, and HMSA provided more than $175 million in COVID-19-related support and financial relief to members, employers, providers, and communities. The page notes milestone anniversaries: HMSA commemorated 85 years of caring for families, friends, and neighbors in 2023, and its Centers in Hilo, Honolulu, and Pearl City turned 10 in 2023, with centers also in Kahului and Lihue. In 2024, HMSA's Online Care celebrated 15 years of providing members and anyone in Hawaii with access to virtual non-emergency care, and in 2025 the HMSA Kaimana Awards & Scholarship program reached its 20th year of honoring outstanding high school seniors and schools with scholarships and awards. The page also describes HMSA continuing to support providers by advancing value-based care and payment models, reducing administrative burden, and launching a new mobile self-service tool and new provider portal, HHIN+. It states that the U.S. Office of Personnel Management transitioned U.S. Postal Service members to a Postal Service Health Benefits Program, which HMSA supports by providing health plan options to eligible post office employees, retirees, and their family members starting in 2025, and that HMSA introduced a new strategy, branded We Care, to invest in its employees and support the company's mission by focusing on its purpose, people, work, and total rewards.
