Per ICD-10-CM guidelines, Section I., A., 15.,
For N17.0, “Acute kidney failure with tubular necrosis” is thus interpreted as “Acute kidney failure due to tubular necrosis”. This is in agreement with the provider’s diagnosis: “oliguric acute kidney injury likely secondary to multifactorial ATN”.
“Acute kidney injury” and ”acute kidney (renal) failure” are synonymous (Goyal et al., 2023).
Therefore, N17.0 would be the proper code.
Also, whatever the “multifactorial” causes are for the tubular necrosis, you need to code them as underlying conditions, per the instruction under N17 in the ICD-10-CM manual.
