Medical Mutual

What Medical Mutual does

Medical Mutual Insurance Company of Maine is a mutual insurance company founded in 1978 that provides medical professional liability (malpractice) insurance to physicians, surgeons, hospitals, health systems, nursing homes, and allied healthcare facilities across Maine, New Hampshire, Vermont, and Massachusetts. The company holds a 36.81% market share in Northern New England — more than double the #2 carrier at 14.48% — and is exclusively endorsed by the Maine Hospital Association, Maine Medical Association, Maine Osteopathic Association, and Vermont Medical Society. It is rated A (Excellent) by A.M. Best and reports over $240M in policyholder surplus and $450M in admitted assets, with 3,700+ physicians insured and a 99% policyholder retention rate. The company is policyholder-owned (mutual structure) and has declared 24 dividends since inception totaling more than $85M returned to policyholders, with dividends in 17 of the last 18 years.

The core product portfolio centers on Medical Professional Liability Insurance (standard $1M/$3M claims-made coverage) for physicians and practices, Hospital & Health Systems Coverage (integrating professional and general liability), Nursing Home Insurance, and Allied Healthcare Services Insurance. Differentiated add-ons include the rShare risk-sharing program (customizable deductibles from $5K per claim plus co-participation), Slot Coverage (insuring a position rather than an individual physician), integrated $100K base cyber coverage (up to $10M available), Physicians Administrative Defense (PAD), Umbrella Excess, Group Policies, and Locum Tenens Coverage. Pricing is quote-based with flexible payment options including an industry-only 9-month interest-free installment plan; rates have been flat for five years. Technology infrastructure is built on the Oasis policy administration platform with a DocuSign integration for credentialing workflows.

The business model generates revenue through recurring premium subscriptions (claims-made and occurrence-based), with surplus returned to policyholders as dividends when loss experience is favorable. Distribution is hybrid: a network of authorized independent insurance agents across all four states (Cross Insurance, Clark Insurance, Arthur J. Gallagher, PIMA, USI, Willis, NFP) plus direct application for physicians in ME/MA/NH, and dedicated enterprise underwriting for hospitals and large practices. Marketing relies on thought leadership via risk management webinars, an annual educational seminar, on-site presentations, and newsletters, with the physician-led Claims Committee serving as the central credibility mechanism for claims outcomes (80% closed without indemnity payment, 90% trial success rate).
