The patient's birth date on the CMS-1500 claim form is entered in what format?

• A. MM/DD/YYYY
• B. DD/MM/YYYY
• C. YYYY-MM-DD
• D. YYYY/MM/DD

Answer: (A)

Dates of birth on the CMS-1500 claim form are entered in the US standard month/day/year format, using four digits for the year and separated by slashes. This means something like 04/12/1985. This convention avoids ambiguity for month and day order and keeps the year clear across centuries, which is important for patient identification and eligibility checks on a national form. The other formats would swap month and day (day/month/year), or place the year first (year/month/day), or use different separators (such as dashes) that aren’t part of the CMS-1500 design. Therefore, the correct format is MM/DD/YYYY.
