LOINC Code 78973-5: CT scanogram Lower extremity - bilateral for leg measurement WO contrast

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Multisection for leg measurement^WO contrast. It is commonly used with the system or sample type Lower extremity.bilateral.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Order vs observation: Both
• Method: CT.scanogram

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• CT scanogram Lower extremity - bilateral for leg measurement WO contrast
• Multisection for leg measurement^WO contrast
• A computed tomography (CT) scanogram is a low-dose, non-contrast radiation imaging modality used for a variety of indications, including ante version, femur length and tibial length. A CT scanogram can be used for leg measurement when there are flexion contractures that would distort anteroposterior images, and when lateral images from a CT can provide bone leg measurement in patients with leg inequalities (e.g., ununited fracture). CT measurements of anteversion are based on the angle of rotation of the femoral neck relative to the femoral condyles and are used to determine whether there are rotational components, not simply a discrepancy in leg length.
