Change Scenario 2 to the following: Mrs. Smith is a 75-year-old female on a Medicare Fee-For-Service plan with long standing chronic obstructive pulmonary disease (COPD) who has had slowly and progressively worsening shortness of breath with activity. In the office, her room air saturation after a 5-minute walk is found to be 84%. She has additional evaluation that reveals no new findings. Dr. Good wants to initiate home oxygen therapy for Mrs. Smith. Dr. Good is completing an order for home oxygen therapy.  The EMR initiates a query to the CRD Server used by her payer that includes the code for a portable oxygen generator. An alert appears on the EMR order entry screen notifying Dr. Good that specific testing and documentation is required to substantiate the need for a home oxygen therapy and specifically for a portable oxygen generator. The EMR allows Dr. Good to immediately document the required information by starting DTR. DTR retrieves specific documentation templates which have already been populated with information from their EMR. They complete the remaining documentation requirements that require clinical input, signs the documentation, and includes it in Mrs. Smith’s medical record. They leave the remaining portion of the documentation to be completed by their administrative staff who will find an appropriate supplier and forward the order and documentation. * Note: This flow envisions the use of the Order Sign hook, which allows guidance to be returned while the user is in the process of signing the order.
