How frequently are CPT codes updated?

• A. Monthly
• B. Annually
• C. Daily
• D. Every five years

Answer: (B)

CPT codes are updated annually by the American Medical Association. Each year, new codes are added, existing codes are revised, and some are deleted to reflect advances in medical practice and technology. The changes are published in a new edition and become effective January 1 of the following year, so clinics, insurers, and billing systems adopt a single updated set each year. This makes annual updates the standard, rather than monthly, daily, or every five years.
