What type of codes does PC/TC indicator 4 specify?

The correct answer highlights that PC/TC indicator 4 designates diagnostic tests that include both professional and technical components. This classification is important in medical billing and coding as it recognizes procedures where separate reimbursement applies.

When a service is categorized under this indicator, it typically means that it requires both professional interpretation (the medical provider’s service) and technical execution (the equipment and support staff needed to perform the test). Understanding these distinctions is crucial for accurate billing, ensuring that both components of the service can be appropriately reimbursed.

In contrast, the other choices indicate specific components or types of tests that don’t apply under indicator 4. Technical component only codes refer solely to the technical aspects without a professional component, while professional component only codes focus exclusively on the provider's interpretation without the technical side. Global test codes encompass a bundled approach where both elements are combined into a single code, which differentiates them from the codes indicated by PC/TC indicator 4 that specifically separates the professional and technical components.
