What is the required format for the date of current illness or injury in Block 14?

In Block 14 of the CMS-1500 form, the date of the current illness or injury must be recorded in either a 6-digit format (MM/DD/YY) or an 8-digit format (MM/DD/YYYY), but it is essential to use one format consistently throughout the claim. This requirement ensures clarity and uniformity in reporting dates, which is crucial for processing claims accurately and efficiently.

Using a consistent format helps avoid confusion and potential delays in processing due to misinterpretation of the date. Therefore, choosing either format is acceptable as long as the same one is used throughout the document, which enhances the overall integrity of the claim submission.
