75890-4

LOINC code 75890-4 identifies "Abbreviated Injury Scale predot code AAAM". The Abbreviated Injury Scale (AIS©) predot code that reflects the patient's injuries. The predot code is the six digits preceding the decimal point of an associated AIS severity code, shown as 12(34)(56).7 where 1 = body region, 2 = type of anatomical structure, 3,4 = specific anatomical structure, 5,6 = level of injury and 7 = severity score based on predot code. For example, a femoral shaft fracture may be coded as 851814.3 where 851814 if the numerical identifier (predot code) and 3 is the AIS severity score [LOINC: 75891-2]. The predot code is further defined as 8 = Body Region: Lower Extremity, 5 = Type of Anatomic Structure: Skeletal, 18 = Specific Anatomic Structure: Femur, and 14 = Level of injury: Shaft.

This code measures Abbreviated Injury Scale predot code in ^Patient. It belongs to the TRAUMA class in the LOINC classification.

LOINC (Logical Observation Identifiers Names and Codes) is a universal standard for identifying laboratory and clinical observations. It is maintained by the Regenstrief Institute and used worldwide for health data exchange.
