Which value is entered in the ICD-10-CM version field after October 1, 2015?

• A. 10
• B. 9
• C. 0
• D. 1

Answer: (A)

The value in the ICD-10-CM version field indicates which coding system version is being used for diagnosis codes. After October 1, 2015, the standard became ICD-10-CM, so you enter 10 to denote ICD-10-CM. This reflects the mandatory transition implemented under HIPAA, ensuring payers recognize the codes as ICD-10-CM rather than ICD-9-CM. Using 10 confirms the claim uses the newer, more detailed code set; older or invalid values wouldn’t indicate ICD-10-CM and could cause processing issues.
