When to bill global maternity?

Could you please elaborate on the concept of "billing global maternity"? Are you referring to the timing of when to invoice or charge for maternity-related services that span multiple countries or regions? Or is it perhaps a question about how to handle billing for international maternity insurance coverage? Clarifying the context would help me provide a more accurate and informative response. In general, billing for maternity services can be complex, especially when it comes to global coverage, so understanding the specifics of the situation is crucial.
