The New Mexico Office of Superintendent of Insurance (OSI) published a bulletin announcing changes made to the Medical Malpractice Act and what that means for insurers writing medical professional liability policies in the state.

The Superintendent expects that the changes made to the Act should result in less costly premiums for medical professionals. The Act places new rules and caps on punitive damages, redefines the meaning of occurrence, and adds a definition for "value of accrued medical care and related benefits."

Insurers must formally file their new rates through SERFF, or if no premium decreases are expected, they must file a notice in Case No. 2026-0088. The amended Medical Malpractice Act is effective May 20, 2026.
