Which of the following is NOT one of the four HIPAA code sets?

The correct choice identifies PCT as not being one of the four HIPAA code sets. Under the Health Insurance Portability and Accountability Act (HIPAA), the designated code sets include ICD-10-CM, which is used for diagnosis coding; HCPCS (Healthcare Common Procedure Coding System), which encompasses codes for procedures, supplies, and services; and CDT (Current Dental Terminology), specifically for dental procedures.

PCT, or the Procedure Coding Terminology, does not exist as an official code set under HIPAA regulations. Understanding the recognized code sets is crucial for compliance with HIPAA and ensuring accurate billing and documentation in healthcare practices. This knowledge is foundational for those managing physician practices, as it helps in navigating coding standards and regulatory requirements effectively.
