Did You Know?

Effective October 1, 2023, the Alphabetic Index to the code book changed how we are to code elevated Troponin level again.


Why It Matters?

Prior to October 1, 2023, the Alphabetic Index led coders to assign R77.8, Other Specified Abnormalities of Plasma Protein, for an elevated Troponin level, while the advice from Coding Clinic, 2Q 2019, page 6 instructed coders to use R79.89, Other Specified Abnormal Lab Findings of Blood Chemistry. Even though the code book instructions take precedence over Coding Clinic advice, this confused many coders and caused coding errors when coding this condition.


What Can I Do?

Inform coders that the Alphabetic Index has now changed and that R79.89, Other Specified Abnormal Lab Findings of Blood Chemistry is the correct code for an elevated Troponin level.
