Blog 3: How Policy Change Happens — Statutes, Regulations, and Advocacy

Improving behavioral health access requires more than awareness; it requires navigating statutory and regulatory systems that determine how care is delivered and funded. If access gaps are shaped by policy decisions, then meaningful change must also occur through legislative and regulatory action.

Statutory Mechanisms: Laws That Shape Behavioral Health Access

Statutory mechanisms refer to laws passed by legislative bodies.

At the federal level, Congress shapes behavioral health access through coverage and funding laws. Examples include:

• The Mental Health Parity and Addiction Equity Act (2008), which requires that mental health and substance use disorder benefits be no more restrictive than medical and surgical benefits.

• The Affordable Care Act expanded behavioral health coverage and classified mental health services as essential health benefits.

At the state level, legislatures determine funding and policy direction for Medicaid, workforce development, and behavioral health systems.

Arizona Legislative Example: In recent years, the Arizona Legislature passed funding for expanding the state’s crisis response system, including the implementation of the 988 mental health crisis hotline and related mobile crisis teams. This legislative action allocated state resources to crisis infrastructure and helped operationalize federal policy within Arizona. These legislative decisions demonstrate how statutes can directly influence behavioral health systems and access.

Regulatory Mechanisms: Turning Law into Practice

Once a law is passed, regulatory agencies interpret it through rules and guidance.

At the federal level:

• Centers for Medicare & Medicaid Services (CMS) determines how Medicaid and Medicare reimburse behavioral health services and enforces parity requirements.

• The Substance Abuse and Mental Health Services Administration (SAMHSA) administers grant programs, establishes program standards, and disseminates best practices.

• Health Resources and Services Administration (HRSA) identifies mental health professional shortage areas and funds training and workforce support.

In Arizona:

• Arizona Health Care Cost Containment System (AHCCCS) manages Medicaid behavioral health benefits and determines provider reimbursement structures.

• Arizona Department of Health Services (ADHS) oversees behavioral health program standards and crisis system implementation.

Through these regulatory processes, agencies shape which services are sustainable, how providers are paid, and how programs are enforced.

What Policy Advocates Must Navigate

To accomplish policy change, advocates must understand both legislative and regulatory pathways:

1. Monitoring proposed legislation at the federal and state levels

2. Participating in public comment periods for regulatory rulemaking

3. Meeting with lawmakers and agency staff to share data and stories

4. Providing testimony during committee hearings

5. Collaborating with coalitions and advocacy organizations to amplify influence

Advocates must also understand budget cycles, because many access barriers are tied not to lack of awareness, but to how funding is allocated.

Why This Matters for Nursing Leadership

As a nurse and graduate student, understanding statutory and regulatory processes allows me to think beyond bedside care. Workforce shortages, reimbursement gaps, and crisis-driven systems are not accidental — they emerge from policy decisions in legislative chambers and agency offices.

Improving behavioral health access requires nurses to be engaged with these systems. Policy advocacy is not separate from nursing practice — it is an extension of it.

If behavioral health access is a policy problem, then nurses must be part of the policy solution.
