Effective September 1, 2026, MassHealth requires providers to transition maternity care billing for new patients to evaluation and management (E/M) codes with TH modifier instead of global maternity CPT codes (59425, 59426, etc.). Existing patients with first prenatal visits before September 1, 2026 continue using legacy codes; new patients after that date must use appropriate E/M codes (99202-99205 for new patients, 99211-99215 for established patients, plus telemedicine codes) based on medical decision-making level.
