2025 ICD-10-CM code N17.1
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Renal diseases - Acute kidney failure Diseases of the genitourinary system (N00-N99) Feed
Acute kidney failure with acute cortical necrosis.
Medical necessity is established by the presence of acute kidney failure with acute cortical necrosis as evidenced by clinical presentation, laboratory findings, and/or imaging studies.Treatment such as dialysis or supportive care may be medically necessary depending on the severity and patient's clinical status.
The clinical responsibility involves diagnosing the acute kidney failure, identifying the underlying cause (e.g., obstetric complications, sepsis, trauma), managing the acute phase (fluid and electrolyte balance, blood pressure control), and potentially initiating dialysis or referring to nephrology for long-term management.

- Acute kidney failure and chronic kidney disease (N17-N19)
In simple words: This code describes a serious kidney problem called acute kidney failure caused by damage to the outer layer of the kidney. This damage happens when the kidney doesn't get enough blood flow.It can lead to other problems like too much fluid in the body and an imbalance of potassium. In some cases, it may become a long-term kidney problem requiring dialysis or a kidney transplant.
N17.1, Acute kidney failure with acute cortical necrosis, is an ICD-10-CM code that classifies acute kidney failure resulting from ischemic necrosis of the renal cortex.This condition is characterized by significantly reduced renal arterial perfusion due to factors such as vascular spasm, microvascular injury, or disseminated intravascular coagulation. The necrosis is typically extensive, though focal forms can occur.The medulla, juxtamedullary cortex, and a thin rim of subcapsular cortex are usually spared.Complications include hyperkalemia, fluid overload, and the potential development of chronic renal failure (requiring dialysis or transplantation) in 30-50% of cases.
Example 1: A pregnant woman develops acute renal failure in the third trimester due to abruptio placentae (placental abruption).The diagnosis of N17.1 is made based on clinical presentation, laboratory findings (elevated creatinine, BUN), and imaging studies., A patient presents with acute renal failure following septic shock due to severe infection.The physician documents evidence of acute cortical necrosis on imaging and makes a diagnosis of N17.1., A patient sustains significant trauma to the abdomen resulting in acute kidney failure and acute cortical necrosis.The diagnosis of N17.1 is supported by imaging findings and laboratory values demonstrating acute kidney injury, which are documented in the patient's medical record.
Detailed history and physical examination, including obstetrical history if applicable; laboratory results (serum creatinine, BUN, electrolytes, complete blood count); imaging studies (ultrasound, CT scan); documentation of any underlying conditions contributing to the renal failure; documentation of treatment provided and response to treatment.
** The incidence of renal cortical necrosis is higher in developing countries.Obstetric causes account for a significant portion of cases.The prognosis can vary depending on the extent of necrosis and the presence of underlying conditions.
