Which symbol in the CPT Manual indicates a change in the code description since the last edition?

The symbol that indicates a change in the code description since the last edition in the CPT Manual is the triangle. This symbol, when used next to a code, signifies that there has been a modification in the language of the code description, which requires users to review the details carefully as there may be important updates to note for accurate coding.

The triangle helps coders quickly identify which codes have undergone changes, facilitating better compliance and a more accurate understanding of the services they represent. Being attentive to these symbols is crucial for healthcare professionals to ensure proper coding practices and reimbursement processes.

While the other symbols serve different purposes — such as the bullet indicating new codes, the plus sign indicating add-on codes, and the circle with a line indicating deleted codes — they do not signify changes to code descriptions, highlighting the unique role of the triangle in this context.
