ICD-10-CM Code For Abnormal Serum Enzyme Levels: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R74 includes abnormal serum enzyme levels such as elevated transaminases, alkaline phosphatase, and other enzyme abnormalities that indicate possible liver, biliary, or muscle pathology. These ICD-10-CM diagnosis codes are used to document laboratory-detected enzyme abnormalities when a definitive underlying diagnosis has not been established, capturing severity and organ involvement when specified. Accurate coding within the ICD-10-CM R74 group supports complete clinical documentation and appropriate claim adjudication.

ICD-10-CM R74: Abnormal Serum Enzyme Levels Overview
This group represents abnormal findings of serum enzyme concentrations detected on laboratory testing, typically involving hepatic or muscle enzymes. It targets biochemical abnormalities rather than a specific disease diagnosis and may signal liver injury, muscle damage, or other metabolic disturbances. Accurate coding matters because it distinguishes laboratory abnormalities from definitive disease diagnoses and supports appropriate clinical documentation and claim processing.
