Provider Credentialing in Hawaii | Arctic Health

Hawaii is unique in the US healthcare landscape because of its 1974 Prepaid Health Care Act, which requires most employers to provide health insurance to employees working 20+ hours per week. This law — predating the ACA by 36 years — has produced some of the lowest uninsured rates in the country and a mature managed care market. The vast majority of Hawaii residents have commercial or managed Medicaid coverage, making network participation essential for sustainable practice.

Hawaii Medical Service Association (HMSA) is the Blue Cross Blue Shield plan for Hawaii and by far the dominant commercial insurer on Oahu and statewide. Kaiser Permanente Hawaii is the second largest carrier, operating as a staff-model HMO with its own employed physician network — independent providers cannot credential with Kaiser but must credential with HMSA and other plans.

MedQUEST is Hawaii's Medicaid managed care program, operating through HMSA and United Healthcare Community Plan of Hawaii (formerly ʻOhana Health Plan). Each plan requires separate credentialing. Hawaii expanded Medicaid under the ACA, though the expansion impact was smaller than most states given existing coverage laws.

Arctic Health helps Hawaii providers credential with HMSA and all MedQUEST managed care plans, with expertise in Oahu's concentrated market and the inter-island credentialing logistics for providers serving neighbor island practices.
