Resubmitting NMS Transactions

When a prescription for a narcotic or controlled medication is filled and sent to NMS, the transaction can fail or be rejected. Any issues must be fixed before resubmitting the transactions. It is crucial that NMS transactions be completed.

If there is an error when submitting a claim to NMS, it will appear in the 3rd Party tab.

To resolve any errors:

  1. Review the response messages and take the necessary corrective action.
  2. Select Submit.
