Mental Health CPT Codes Introduction

Mental health billing can be complex, but having a clear understanding of the correct CPT codes is critical. Proper coding helps ensure accurate reimbursement, reduce claim denials, and streamline operations for behavioural health and psychiatric practices.

What Are Mental Health CPT Codes and Why Are They Important in Mental Health Billing?

CPT (Current Procedural Terminology) codes are standardized codes used by healthcare providers to describe medical, surgical, and diagnostic services. In the context of mental health services, they are essential for documenting care, billing insurance companies, and supporting continuity of care.

Misused or outdated codes can result in claim denials and lost revenue, which makes staying up to date on the latest codes more important than ever. Learn more about CPT code structures and updates at AAPC.com.
