LOINC Code 89927-8: CT Heart and aortic root WO contrast for calcium scoring + CTA W contrast IV

89927-8 is a LOINC code used to identify CT Heart and aortic root WO contrast for calcium scoring + CTA W contrast IV in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Multisection for calcium score^WO contrast && Multisection^W contrast IV. It is commonly used with the system or sample type Chest>Heart+Aortic root.

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 calcium score^WO contrast && Multisection^W contrast IV. It is commonly used with the system or sample type Chest>Heart+Aortic root.

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 && CT.angio

What it does not mean

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

Key facts

CT Heart and aortic root WO contrast for calcium scoring + CTA W contrast IV
Multisection for calcium score^WO contrast && Multisection^W contrast IV
CT scan of the heart and aortic root without contrast for calcium scoring followed by CT angiography with contrast. Calcium scoring is typically done based on the coronary arteries, but evaluating aortic valve calcification may be done as part of the radiologic assessment prior to transcatheter aortic valve replacement.
