AM Best has upgraded the credit ratings of The Doctors Company and its core subsidiaries following the recent acquisition of ProAssurance Corporation. As the second-largest writer in the U.S. medical professional liability market, the group is now rated A+ for financial strength.
Why it matters
The ratings upgrade reflects an improved business profile and enhanced scale for the insurer. While the acquisition of ProAssurance is expected to pressure underwriting performance in the near term, the firm maintains a strong level of risk-adjusted capitalization.
The Doctors Company, the second-largest U.S. medical professional liability insurer, received an upgrade to an A+ financial strength rating from A. This shift follows its June 2026 acquisition of ProAssurance Corporation, intended to bolster long-term earnings through greater scale.
The players

The details
The upgrade follows an assessment of the company's favorable business profile and its diversified book of business.

Medical practices and healthcare facilities should monitor how these shifts in the liability market impact coverage stability and premium costs. Operators should consult with their insurance brokers to assess whether their specific carrier's financial profile remains aligned with long-term risk management needs.
The takeaway
The upgrade signals improved stability for the firm despite the integration risks following a major acquisition. Healthcare operators should keep the A+ financial strength rating in mind when performing their annual reviews of professional liability coverage and carrier risk profiles.
