While we’re updating our billing system, your bills will be split into two separate balances. The legacy billing system will show the balance for medical services that you received before [MM/DD/YYYY], and the new, current system will show the balance for medical services that you receive after [MM/DD/YYYY]. You’ll have different billing account numbers for the legacy billing system and the current one.
