Elevated Liver Enzymes ICD-10-CM codes

How to code Elevated Liver Enzymes

R74.01 is elevation of levels of liver transaminase levels, and it is the code for transaminitis, transaminasemia, elevated ALT, and elevated AST. Elevated LDH is R74.02. Elevated alkaline phosphatase and other hepatic enzymes are R74.8, and R74.9 is an abnormal serum enzyme level, unspecified.

The index sends an abnormal liver function test without detail to R79.89, and an abnormal liver function study to R94.5. The index sends elevated bilirubin to R17 (unspecified jaundice), even without visible jaundice. Gilbert syndrome is E80.4 and other disorders of bilirubin metabolism are E80.6.

These are findings, so they are not coded once the cause is diagnosed, for example K76.0 for fatty liver or K75.81 for NASH. See the fatty liver disease guide for those codes.
