All MassHealth providers are required to understand and comply with the rules that apply to their specific provider type, as well as rules that apply to all providers.
This page provides important information for all providers, such as Subchapters 1 through 3 (billing regulations) and Subchapter 5 (billing instructions).
While all of these subchapters are important for all providers, providers should also pay close attention to Subchapter 4, which outlines the requirements and conditions of a specific program. Providers must comply with the rules in Subchapter 4 at all times.
Providers should also review Subchapter 6, which outlines covered services (services and codes) for each program.
