Definition: This field contains the DRG for the transaction. Interim DRG's could be determined for an encounter. Refer to External Table 0055 - Diagnosis Related Group in Chapter 2C, Code Tables, for suggested values.
Definition: This field indicates the determined Major Diagnostic Category (MDC) value. Refer to External Table 0118 - Major Diagnostic Category in Chapter 2C, Code Tables, for suggested values.
Components:
Definition: This field contains the lower and upper trim points as calculated for this DRG..
Example as used in Germany: The "lower trim point" is equivalent to 1/3 of the average length of stay for patients having this DRG. The "upper trim point" is equivalent to 3 times the average length of stay. It is marked as the right dotted line within the graphics below.
The following graphics provides an overview of the German usage:
The gray boxes represent the amount of cases according to the length of stay. The higher and lower 2,5% outliers (white boxes) are cut off. The average length of stay is calculated thereof and is represented by the middle dotted line. From that the lower trim point is calculated by dividing by 3, the upper trim point is the average multiplied with 3.
Definition: This field contains the average length of stay in days, calculated as the geometric mean value, allocated to the determined DRG.
Definition: Each DRG has its own relative weight (cost weight) which is calculated (defined) by official institutions. This value is the basis for calculating other values, e.g., the effective weight.
