The disposition is likely to be implemented in the next update to the HL7 QRDA-I, DSTU Release 3 standard. This disposition is to HL7 QRDA-I, DSTU R3 only, it does not apply to HL7 QRDA-I, R2 and has no impact to the reporting for the 2015 reporting year.
For the 2015 reporting year, the HQR receiving system is aware of this issue and will provide a workaround fix.
