Our providers use a couple different diagnosis codes when they are referring to AST/ALT being elevated/abnormal in a CMP panel. The codes they use are R74.8 - Abnormal Levels of other serum enzymes or R94.5 - Abnormal results of liver function studies or K76.89 - Other specified diseases of the liver. Which would be more appropriate to code when patients AST/ALT is abnormal/elevated? Thanks for your expertise!

ICD-10-CM Code R74.8 (Abnormal levels of other serum enzymes) is a applicable to: Abnormal level of acid phosphatase, Abnormal level of alkaline phosphatase, Abnormal level of amylase, Abnormal level of lipase [triacylglycerol lipase].

Also, common medical terminologies for this diagnosis can be used as follows:

  • Alkaline phosphatase raised
  • Elevated alkaline phosphatase
  • Elevated amylase
  • Elevated CPK
  • Hyperamylasemia
  • Increased Creatine Kinase Level
  • Macroamylasemia
  • Serum amylase raised


For R94.5 (Abnormal results of liver function studies), common medical terminologies for this diagnosis can be used as follows:

  • Abnormal liver enzymes
  • Abnormal liver function
  • Abnormal liver function study
  • Elevated liver function test
  • Liver enzymes abnormal
  • Liver function tests abnormal


For K76.89 (Other specified diseases of liver), common medical terminologies for this diagnosis can be used as follows:

  • Hepatoptosis
  • Hydrohepatosis
  • Lesion of liver
  • Liver cyst
  • Liver lesion
  • Liver nodule
  • Nodule of liver

And code K76.89 can be applicable to, Cyst (simple) of liver, Focal nodular hyperplasia of liver, Hepatoptosis.

However, for ALT and AST raised level diagnosis code leads to R74.0 (Nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH]).

For the code R74.0, common medical terminologies can be used as follows:

  • ALT (SGPT) Raised Level
  • AST/SGOT Raised Level
  • Elevated alanine aminotransferase (ALT)
  • Elevated AST (liver function test)
  • Elevated lactate dehydrogenase (LDH)
  • Elevated transaminase measurement
  • Increased aspartate transaminase level
  • Increased transaminase level
  • Serum lactate dehydrogenase level elevated

Hope this helps!
