Should notes in CPT be applied to all codes located under a heading?

Yes, notes in the Current Procedural Terminology (CPT) should be applied to all codes located under a heading. These notes provide essential guidance on coding and billing practices, clarifying the appropriate use and context of the codes. Ignoring these notes may lead to incorrect coding, which can affect reimbursement and compliance with regulations. Therefore, it's important for coders to review and apply the notes to ensure accurate coding.
