What does the "star" symbol indicate in CPT coding?

The "star" symbol in CPT coding signifies that a particular code has been deleted. This symbol serves to inform coders that the code is no longer active and should not be used for reporting services. Deletions may occur because the service may no longer be performed, has been replaced with a new code, or has been deemed unnecessary based on changes in medical practice.

The other choices represent various aspects of coding but do not align with the function of the "star" symbol. For example, new codes added to the system are usually denoted with a different symbol (upward arrow), while codes that have been replaced are likely noted with a different marker indicating that they have been superseded. Codes that are frequently used do not have a specific symbol associated with them, as their usage is determined by the context in which they are applied rather than indicated by a special character in the code itself. Understanding the significance of symbols like the "star" helps coders accurately interpret the coding guidelines and maintain proper billing practices.
