When patient data is loaded into the Clinigence system, many data items are automatically mapped to items in the Code Lists. This occurs when the match is simple and unambiguous, such as Birth dates from the patient profile, CPT codes matching numerically, and ICD codes matching numerically or by description. Other items must be mapped manually from the patient data to an appropriate Code List. This is generally accomplished by selecting the appropriate Domain for the patient data item (Diagnosis, Treatment, Vital Signs, etc) and searching for a counterpart in one of the Code Lists. Then the person mapping the data will determine what is a match based on description of the patient data item and the available code list item.
As you can see from the graphic, several items in the patient data can be mapped to a single item in the code list.
Patient data that is documented in free-text fields or as comments are much more difficult to map than data documented in a structured format (such as selectable observation results, treatments and diagnoses). In addition, if the patient data is documented as text or assigned to an unexpected domain, it will not be mapped. For example, if the measure requires the patients to have a diagnosis of Diabetes and the patient data item is labeled “Notes” or "Reason" that item will not be mapped and the patient will not qualify for the measure.
