About coding transaminase level elevated
The ICD-10-CM code for transaminase level elevated is R74.01 (Elevation of levels of liver transaminase levels).
Within R74.0 (nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH]), R74.01 is specifically for elevation of levels of liver transaminase levels. Related codes cover lactic acid dehydrogenase [LDH] (R74.02).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 947 (Signs and Symptoms with MCC, relative weight 1.261) and DRG 948 (Signs and Symptoms without MCC, relative weight 0.7835), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
