About coding Azotemia
The ICD-10-CM code for Azotemia is R79.89 (Other specified abnormal findings of blood chemistry). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on R79.89.
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.
