I'm hearing from sources that the extent of the failed documents was at such a high level that the fed has expanded the investigation to include all current and former pps locations, sales representatives, former mid level managers, the current and former executive teams. Another item was a marketing gimmick telling large referral sources that they were performing a study about o2 saturation levels on conserving devices that requested the referral to order o2 with pps and there was no charge for the study or to the patient and they went ahead and billed. So the investigation is ongoing and will take more time than the ordinary investigations usually do.
