About coding Troponin elevated
The ICD-10-CM code for Troponin elevated is R79.89 (Other specified abnormal findings of blood chemistry).
Within R79.8, choose R79.89 (Other specified abnormal findings of blood chemistry) only when documentation doesn't support a more specific option: abnormal blood-gas level (R79.81), elevated C-reactive protein (CRP) (R79.82) and abnormal findings of blood amino-acid level (R79.83).
Use an additional code to identify any retained foreign body, if applicable (Z18.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
