What symbol indicates multiple procedure exemption codes in CPT coding?

The symbol that indicates multiple procedure exemption codes in CPT coding is represented by a circle with a line through it. This symbol serves to highlight codes that are exempt from the multiple procedure payment reductions that typically apply when more than one procedure is performed during the same session. By using this visual cue, coders and billers can easily identify which procedures may be billed at full value, ensuring that proper reimbursement can be achieved without inadvertently applying reductions that are not applicable.

The other symbols, while each has its own significance within the CPT coding system, do not denote exemption codes. For instance, the plus (+) symbol indicates add-on codes that are used in conjunction with primary codes, and the square symbol denotes unrevised codes, which can lead to confusion if misinterpreted. The pound (#) symbol is used for codes that have special instructions or guidelines, but none of these represent the multiple procedure exemption specifically. Therefore, understanding the meanings behind these symbols is crucial for accurate coding practices.
