Which symbol indicates exemptions to modifier 51?

• A. Circle with a slash through it
• B. Asterisk
• C. Hash
• D. Star

Answer: (A)

Understanding exemptions to Modifier 51 helps ensure proper reimbursement when multiple procedures are performed. In CPT coding, the circle with a slash through it is the symbol used to mark codes that are exempt from Modifier 51. This means that even if several procedures are billed in one encounter, this particular code should not have Modifier 51 appended to it. The symbol signals that the code already reflects its scope or is not eligible for multiple-procedure reporting, so applying 51 would be incorrect. The other symbols listed don’t indicate 51 exemptions; they’re used for different coding instructions or conventions in the CPT system.
