Instructions in §§2010.1 and 2010.2 (see below) that require the reporting of 8-digit dates
in all date of birth fields (items 3, 9b, and 11a), and either 6-digit or 8-digit dates in all
other date fields (items 11b, 12, 14, 16, 18, 19, 24a, and 31) are effective for providers of
service and suppliers as of 10/01/98.

Providers of service and suppliers have the option of entering either 6 or 8-digit dates in
items 11b, 14, 16, 18, 19, or 24a. However, if a provider of service or supplier chooses
to enter 8-digit dates for items 11b, 14, 16, 18, 19, or 24a, he or she must enter 8-digit
dates for all these fields. For instance, a provider of service or supplier will not be
permitted to enter 8-digit dates for items 11b, 14, 16, 18, 19 and a 6-digit date for item
24a. The same applies to providers of service and suppliers who choose to submit 6-digit
dates too. Items 12 and 31 are exempt from this requirement.
