HealthFirst does seem to hint at that on the example, but I don't see that it is required when reading the policy. In fact, it would be pretty impossible to submit all the services on the same claim for a variety of logistics reasons.
1) The POS for the 0500F, 0502F, 0503F would not be the same as for the delivery.
2) They also state in the paragraph above that example to assign the appropriate Z codes for the 0500F, 0502F, 0503F. If you are doing so with Z34.9__ AND Z3A.____ for week of gestation, you would have too many diagnoses to submit on one claim.
3) Each visit will be coded (and therefore submitted) soon after the visit, and each would be linked to a different encounter.
4) You could have multiple providers. Any EHR system I used automatically splits claims with different providers.
They way they provided the example with date range and units I don't think is feasible for the reasons above (and probably others I'm not even realizing).
I guess we'll find out when the policy starts in October 2025 if they don't update by then.
