R74.8 is a billable ICD code used to specify a diagnosis of abnormal levels of other serum enzymes. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code R748 is used to code Elevated alkaline phosphatase

Elevated alkaline phosphatase describes the situation where the levels of alkaline phosphatase exceed the reference range. It can be associated with certain medical conditions or syndromes (e.g., hyperphosphatasia with mental retardation syndrome, HPMRS)
