Maryland Medical Assistance Program and Health Insurance - Collaborative Care Model - Cost Sharing Prohibition

SB 428 prohibits the Maryland Department of Health and certain insurers from charging copays, coinsurance, or deductibles for services delivered under the Collaborative Care Model. This model integrates mental/behavioral health services with primary care in clinics serving Medicaid recipients (Maryland Medical Assistance Program). The law applies to all health insurance plans (including nonprofit plans and health maintenance organizations) covering these services, with one exception: high-deductible health plans may still require deductibles for these services. The bill takes effect January 1, 2027, for new insurance policies and July 1, 2026, for the law itself.
