Update to billed claim status

The "billed" status in Thrive reports when a claim has been exported from Thrive and sent to a clearinghouse. It is not an accurate representation of when the claim was sent to the payer. Claims can sit at the clearinghouse for days, weeks, or even months before they are submitted to the payer. This means the billed but unpaid report in Thrive is always overstated, even if only by one day, though some are grossly overstated depending on various issues that occur at the clearinghouse. My idea is to create a new claim status that will indicate when the claim was transmitted to the payer, using data (such as a 277 file or copy of the 837) from the clearinghouse. This new claim status should be reportable. We could create a new report, or add it as a column on the billed by date range and billed but unpaid reports.
