LOINC Code 81398-0: Mitral valve Maximum E-wave velocity/Flow propagation velocity.E wave by US.M-mode+doppler.A4C

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 Blood flow velocity.E wave.max/Flow propagation velocity.E wave. It is commonly used with the system or sample type Mitral valve.

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: US.M-mode+doppler.A4C

What it does not mean

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