2025 ICD-10-CM code N17.0
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Renal disorders - Acute kidney failure Diseases of the genitourinary system (N00-N99) Feed
Acute kidney failure with tubular necrosis, characterized by sudden and sustained deterioration of kidney function.
Modifiers may be applicable depending on the circumstances of the encounter and the services provided. Consult the appropriate modifier guidelines for details.
Medical necessity for code N17.0 is established by the presence of acute kidney failure with tubular necrosis, demonstrated through clinical presentation, laboratory findings, and imaging (if indicated).The severity of the condition and the potential for irreversible damage necessitate prompt diagnosis and treatment.Medical necessity is also linked to the underlying cause of ATN, such as sepsis, nephrotoxic drugs, or trauma. Treatment including dialysis may be medically necessary.
Diagnosis and management of acute kidney injury (AKI), specifically when it involves acute tubular necrosis (ATN). This includes evaluating the patient's clinical presentation, ordering and interpreting laboratory tests (e.g., serum creatinine, BUN, GFR), determining the underlying cause of AKI, and implementing appropriate treatment strategies, which may involve supportive care, dialysis, or addressing the underlying etiology.Close monitoring of kidney function and electrolyte balance is crucial.
- Diseases of the genitourinary system (N00-N99)
- N17-N19 (Acute kidney failure and chronic kidney disease)
In simple words: This code means the kidneys have suddenly stopped working properly, specifically damaging the tiny tubes within the kidneys that help filter waste and fluid from the blood.This is a serious condition that needs immediate medical care.
N17.0, Acute kidney failure with tubular necrosis, signifies a sudden and sustained decline in kidney function, primarily affecting the renal tubules. This is manifested by reduced glomerular filtration rate (GFR), elevated serum creatinine levels, and often oliguria (reduced urine output).Tubular necrosis, a key feature of this condition, involves damage to the kidney's tubule cells responsible for fluid and electrolyte reabsorption.The condition is often a result of various factors, including ischemia, nephrotoxins, or infections, requiring prompt medical intervention.
Example 1: A patient presents with oliguria, elevated serum creatinine, and a history of recent sepsis.After investigations, acute tubular necrosis is diagnosed as the cause of acute kidney failure., A patient admitted after a traumatic injury exhibits signs of acute kidney failure.Further examination reveals acute tubular necrosis secondary to hypovolemic shock., A patient receiving nephrotoxic medications develops acute kidney failure. Laboratory studies demonstrate elevated creatinine and signs of tubular injury confirming a diagnosis of ATN.
* Detailed history of present illness, including onset, duration, and any associated symptoms (e.g., oliguria, edema, fatigue).* Physical examination findings, noting any signs of fluid overload or dehydration.* Results of relevant laboratory tests (serum creatinine, BUN, GFR, electrolytes, urinalysis).* Imaging studies (if performed, such as ultrasound or CT scan).* Documentation of the underlying cause of AKI (if identified).* Treatment plan, including any supportive measures (e.g., fluid management), dialysis, or specific interventions for the underlying cause.
** The severity of acute kidney failure with tubular necrosis varies widely.The patient's clinical status should be carefully assessed to determine the appropriate level of care and management.This may range from conservative measures to acute dialysis.
