LOINC Code 81176-0: Distance of tumor from circumferential resection margin Macroscopy (Spec) [Length]

81176-0 is a LOINC code used to identify Distance of tumor from circumferential resection margin Macroscopy (Spec) [Length] 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 Distance of tumor from circumferential resection margin. It is commonly used with the system or sample type Specimen.

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 Distance of tumor from circumferential resection margin. It is commonly used with the system or sample type Specimen.

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
  • Method: Macroscopy

What it does not mean

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

Key facts

Distance of tumor from circumferential resection margin [Length] in Specimen by Macroscopy
Distance of tumor from circumferential resection margin
The distance between the tumor and circumferential resection margin (CRM) is recorded for tumors of the gastric cardia. This measurement is facilitated by horizontal sectioning through the tumor. To increase accuracy, the distance between the tumor and the CRM is subsequently measured microscopically [LOINC81184-4]. Involvement of the circumferential resection margin is an indicator of poor prognosis.
