The American Medical Association asked U.S. antitrust regulators to block two proposed mergers that could reshape the health insurance industry.

Anthem Inc. shouldn’t be permitted to buy Cigna Corp. and Aetna Inc. should be blocked from acquiring Humana Inc., the lobbying and professional organization for physicians said in a letter Wednesday to the head of the Justice Department’s antitrust division.
