When billing Novitas for a HH recertification, do I have to wait for the recertification period to be over before submitting a claim? For example, the recert period is 7/1/14 - 8/29/14. Do we have to wait until after 8/29/14 to submit a claim? Or can I submit a claim on, say, 8/8/14? Any help, and resource links is greatly appreciated?
