Am hoping someone can provide direction on 5010 changes with Part A outpatient claims dates of service.

On closer review of the X12 spec for this DTP segment I now see that in 4010 it said:
Required on outpatient claims when revenue, procedure, HIEC or drug
codes are reported in the SV2 segment.
But in 5010 it now reads:
Required on outpatient service lines where a drug is not being billed and
the Statement Covers Period is greater than one day.
These service lines dates of service are key in our processing and adjudication of claims.
Under 5010 do I now need to cover the possibility of NOT receiving service line dates of service for Part A outpatient claims? More specifically, when the claim statement date is one day, to default the service line dates of service (if none provided) to the statement date?
