LOINC Code 90094-4: Rheumatoid arthritis disease severity level [RAPID3]

90094-4 is a LOINC code used to identify Rheumatoid arthritis disease severity level [RAPID3] 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 Rheumatoid arthritis disease severity level. It is commonly used with the system or sample type ^Patient.

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: RAPID3

What it does not mean

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

Key facts

Rheumatoid arthritis disease severity level [RAPID3]
Rheumatoid arthritis disease severity level
The RAPID3® is an index to assess and monitor patients with rheumatoid arthritis, without formal joint counts.[PMID19962621] The cumulative score is the sum of the results of the 10 physical function questions reduced to a score between 0 and 10, the score for pain severity [LOINC: 90036-5], and the patient's global assessment of overall health [LOINC: 90037-3]. The cumulative score is converted to a weighted score that is interpreted as follows: 0-1.0 is near remission (NR); 1.3-2.0 as low severity (LS); 2.3-4.0 as moderate severity (MS); and 4.3-10.0 as high severity (HS). Alternatively, the activity level may be based on the RAPID3 cumulative score as follows: 1-3 is near remission; 4-6 as low severity; 7-12 as moderate severity; and 13-30 as high severity.[https://www.rheumatology.org/Portals/0/Files/RAPID3%20Form.pdf]
