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 Axis measurement increment. It is commonly used with the system or sample type Lensmeter.

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: Observation

What it does not mean

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

Key facts

  • Lensmeter Axis measurement increment
  • Axis measurement increment
  • Axis measurement increment is the specificity to which a lensmeter can measure the axis, typically 1 or 5 degrees. For example, a 5 degree increment allows measurement of 5, 10, 15 degrees, etc., while a 1 degree increment allows finer measurement to a single degree.
