How often are ICD codes updated?

• A. Monthly
• B. Yearly
• C. Weekly
• D. Every five years

Answer: (B)

ICD codes are updated annually. Each year new codes are added for new conditions and treatments, existing codes are revised for clarity, and some codes are retired or merged to keep the system current with medical practice and payer requirements. In the United States, updates to ICD-10-CM (diagnoses) and ICD-10-PCS (procedures) are published each year by the relevant agencies, with the new codes typically taking effect on October 1. This yearly cadence ensures coding stays aligned with evolving medicine and billing rules. Monthly or weekly updates would cause unnecessary disruption, while updates every five years would miss important changes in diagnoses and procedures.
