requiring periodic evaluation of mental health access adequacy by an independent third party.

HB 1812 requires health insurers in New Hampshire to conduct third-party evaluations of mental health network adequacy every three years. These evaluations must measure appointment availability (within 7-14 days), ensure at least 70% of appointments are in-person, and assess provider distribution by specialty (like psychiatry and child services) across the state. The bill directly affects health insurers, mandating they report findings to regulators and the public, with violations subject to administrative fines up to $5,000 per covered person. It aims to ensure mental health services are accessible without unreasonable delays, particularly for vulnerable groups like those with substance use disorders or developmental disabilities.
