["Diagnostic Study, Order": "DXA (Dual energy Xray Absorptiometry) Scan"]
Data Element Scope: This value set may use a model element related to Diagnostic Study.
Inclusion Criteria: Includes concepts that represent a diagnostic study for bone density using DXA scans of the femur, radius, ulna, lumbar spine, hip, calcaneus and skeletal system.
Exclusion Criteria: Excludes order only codes.
Constrained to codes in the DXA (Dual energy Xray Absorptiometry) Scan value set (2.16.840.1.113883.3.464.1003.113.12.1051)
"Diagnostic Study, Order"
Data elements that meet criteria using this datatype should document a request by a clinician or appropriately licensed care provider to an appropriate provider or organization to perform the diagnostic study indicated by the QDM category and its corresponding value set. The request may be in the form of a consultation or a direct order to the organization that performs the diagnostic study. Diagnostic studies are those that are not performed in the clinical laboratory. Such studies include, but are not limited to, imaging studies, cardiology studies (electrocardiogram, treadmill stress testing), pulmonary function testing, and vascular laboratory testing.
Timing: The time the order is signed; author dateTime.
Note: negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype-related actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod.
authorDateTime
The time the data element was entered into the clinical software. Note, some datatypes include both relevant dateTime and author dateTime attributes. When both are present, author dateTime is included to accommodate negation rationale.
The author dateTime addresses when an activity is documented. Documentation can occur at the beginning, during, at the end, or subsequent to the end of the activity. The author dateTime should be used only if the relevantPeriod cannot be obtained or to represent the time negation rationale is documented.
Note: negation rationale indicates a one-time documentation of a reason an activity is not performed. Negation of QDM datatype related actions for a reason always use the author dateTime attribute to reference timing and must not use relevantPeriod.
