Item 24A – Dates of Service (how to format)
For Items 11B, 12, 14, 16, 18, 19, 24A, and 31 of the CMS-1500 claim form, either a 6 or 8-digit date may be entered. If an 8-digit date is used for Items 11B, 12, 14, 16, 18, 19, 24A, or 31, please note the following:
• Item 24A must be reported as one continuous number (e.g., MMDDCCYY), without any spaces
between month, day, and year. By entering a continuous number, the date(s) in Item 24A will penetrate
the dotted, vertical lines used to separate month, day, and year. This will not result in a return or reject.
However, all 8-digit dates reported must stay within the confines of Item 24A.
• The “from” date in Item 24A must not run into the “to” date field, and the “to” date must not run into
Item 24B.
• Dates reported in Item 24A must not be reported with a slash between month, day, and year.
