At the Centers for Medicare & Medicaid Services (CMS) Town Hall meeting on May 25, 2010, CMS provided an alert and information regarding a new process they have developed for small volume RRE users. This is called the Direct Data Entry (DDE) option.
To use this, an RRE must have a volume not to exceed 500 submissions per year. Keep in mind that a query could count as one submission and a report as a second on the same claim. In some situations there could be several submissions per claim. Also, the limit is per RRE, so if an entity has filed one RRE for liability and a second for comp, they would have 500 each available to them.
The alert announcement is available for your reference.
