Determine and assign distance between 2 dates

[cnn96]

Hello people

For my work I have to create age groups. For this I have birth dates and claim dates. I need to determine the grouping based on the distance between claim date and birth date.

For example, if the distance between claim date and birthdate is 28 days then the patient ID comes in the group 3, otherwise it comes in the group 2.

Can anyone help me how to code this?

Thank you in advance.

If your variables contain actual numeric SAS date values, the difference between the two dates is found by subtracting.
