NH| Bulletin #INS 26-019-AB from the New Hampshire Insurance Department provides 2027 plan year guidance for all licensed medical and dental issuers, including QHP and non-QHP products, outlining legal authority, cost-sharing limits, network adequacy expectations, MHPAEA quantitative treatment limit reporting, No Surprises Act and state ground ambulance balance billing compliance, and substance use disorder attestation filing. It sets specific form and rate filing deadlines and procedures, including dual “with waiver” and “without waiver” rate submissions for the state’s Section 1332 reinsurance program, and clarifies that NHID will lead network adequacy reviews using its service-centric tool and review formularies using federal templates and CMS drug tools without requiring issuers to submit tool outputs except upon request.
