The proposed bill aims to mandate insurance coverage for the medically necessary treatment of port-wine stains in individuals aged 18 and younger. It introduces a new section, 47VV, to Chapter 175 of the General Laws, defining key terms such as "port-wine stains," "medically necessary treatment," and "early intervention treatment." The bill stipulates that various insurance policies, including accident and sickness insurance, medical service agreements, and health maintenance contracts, must provide coverage for early intervention treatments related to port-wine stains. However, treatments solely for cosmetic purposes are excluded unless they meet specific medically necessary criteria. Additionally, the bill prohibits imposing more restrictive deductibles or limits on these treatments compared to other medically necessary services.

Furthermore, the bill mandates the Center for Health Information and Analysis to conduct a review of the proposed health benefit to assess the impact of requiring coverage for medically necessary treatments of port-wine stains. This review will consider various factors, including functional impairments and medical complications, while excluding purely cosmetic treatments unless they meet the defined criteria. The findings of this review are to be submitted to several legislative committees by January 1, 2026, ensuring that the implications of the mandate are thoroughly evaluated before implementation.
