About coding Cardiorenal disease hypertension
The ICD-10-CM code for Cardiorenal disease hypertension is I13.10 (Hypertensive heart and chronic kidney disease without heart failure, with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease). The official index lists 6 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I13.10.
Within I13.1, choose I13.10 (with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease) only when documentation doesn't support a more specific option: with stage 5 chronic kidney disease, or end stage renal disease (I13.11).
Use an additional code to identify the stage of chronic kidney disease (N18.1-N18.4, N18.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
