Pair Elevated Creatine Kinase With 'Other' Code

Question: How do I report elevated creatine kinase?

Utah Subscriber

Answer: “Other” code R74.8 (Abnormal levels of other serum enzymes) is your best option for reporting elevated creatine kinase levels.

Helpful: You may see the lab test for creatine kinase (CK) performed on patients with myocardial infarction (MI) symptoms. Typically, CK levels increase around four to eight hours after an infarction occurs. Within about 24 hours, the CK level peaks. After roughly three days, the CK levels return to normal.

You should not assume a patient with elevated CK levels has had an MI though. Only report an MI code if the medical record indicates the patient has had an MI.
