Q&A: Principal diagnosis selection for a patient with CKD, ARF
Temeka Davis, RHIT,
answered this question.
Q: Our team is having a hard time determining a principal diagnosis for a patient with a history of stage 5 chronic kidney disease (CKD) who is receiving chronic hemodialysis and is in acute renal failure (ARF) with volume overload. The patient was admitted to receive the hemodialysis. What ICD-10-CM code should be listed as the principal diagnosis?
A: The principal diagnosis would be the ARF, which is captured with ICD-10-CM code N17.9 (acute kidney failure, unspecified).
The principal diagnosis is assigned based on either the underlying disease or the reason the patient was admitted for dialysis.
Although the patient has a history of CKD, the hemodialysis admission is due to the ARF/injury, which is accompanied with volume overload as a symptom of the ARF.
