Understanding Acute Kidney Failure
Definition and Symptoms
Acute kidney failure, also known as acute renal failure, is a sudden and severe deterioration of kidney function. It is characterized by a rapid decline in the glomerular filtration rate, often accompanied by oliguria (low urine output) and biochemical changes like increased blood urea nitrogen (BUN) and serum creatinine. Symptoms of acute kidney failure may include fatigue, nausea, confusion, swelling, and changes in urine output.
Causes and Risk Factors
Acute kidney failure can have multiple underlying causes, which are often categorized as prerenal (low blood flow), intrinsic (direct kidney damage), or postrenal (urinary tract obstruction). Common causes include dehydration, sepsis, hypotension, glomerulonephritis, acute tubular necrosis, and obstructive uropathy. Risk factors for acute renal failure include advanced age, chronic kidney disease, diabetes, hypertension, and exposure to nephrotoxic medications or contrast dyes.
“Acute kidney injury (AKI) occurs suddenly over a very short period of time, usually two days or less. Some people may have lasting kidney damage after AKI, leading to chronic kidney disease and potential kidney failure.”
ICD-10 Coding for Acute Renal Failure
ICD-10 Codes and Descriptions
The ICD-10-CM coding system provides specific codes for acute kidney failure under the N17 category. The most general code is N17.9 for “Acute kidney failure, unspecified.” Other codes within the N17 range include N17.0 for acute kidney failure with tubular necrosis, N17.1 for acute kidney failure with acute cortical necrosis, and N17.2 for acute kidney failure with medullary necrosis. These codes allow for more detailed documentation and classification of the type of acute kidney injury.
The 2024 edition of ICD-10-CM Diagnosis Code N17 for Acute Kidney Failure became effective on October 1, 2023. The code history of ICD-10-CM Diagnosis Code N17 shows that it was first introduced as a new code effective from October 1, 2015, and has seen no changes in subsequent years up to 2023.
The ICD-10-CM code N17.0, which represents Acute kidney failure with tubular necrosis, became effective on October 1, 2023. N17.0 is commonly attributed to exposure to toxic agents or renal ischemia following severe trauma. Additionally, the ICD-10-CM code N19 represents an unspecified kidney failure and became effective in 2024.
The ICD-10-CM code N17 is used for acute kidney failure diagnosis, where other related codes contain a higher level of detail for specific conditions. The coding system differentiates between acute (N17) and chronic (N19) kidney failure, indicating variations in treatment and management protocols.
Relevant back-references concerning acute kidney failure are made within the code annotations for other related conditions, emphasizing the interconnectivity within the coding system. The inclusion of modifiers such as “Code Also” and “Applicable To” inform on associated conditions that may require additional codes for a comprehensive diagnosis.
acute renal failure icd 10 code
The ICD-10-CM code for acute renal failure or acute kidney injury of nontraumatic origin is N17.9. This is the most general code used to report acute kidney failure or acute kidney injury when the specific underlying cause is not specified. It is a billable code that can be used for medical billing and reimbursement purposes. Accurate assignment of the N17.9 code is crucial for proper documentation and treatment of acute kidney failure.
The ICD-10-CM code N17.8 is also available for reporting other acute kidney failure, such as those related to specific conditions or causes. However, N17.9 remains the go-to code when the underlying etiology is not clearly identified.
To ensure accurate coding and appropriate reimbursement, healthcare professionals must thoroughly document the patient’s condition and differentiate between acute and chronic kidney disease. By correctly utilizing the icd 10 code for acute renal failure, n17.9 code, and acute kidney injury icd-10 code, providers can enhance their medical billing and coding practices, ultimately leading to improved patient care and enhanced revenue cycle management.
“Proper coding and documentation are essential to accurately represent the severity of a patient’s condition and ensure appropriate reimbursement.”
As the healthcare industry continues to evolve, staying up-to-date with the latest ICD-10-CM coding guidelines and best practices is crucial for healthcare providers.

Diagnosis and Classification
Diagnostic Tests and Procedures
Diagnosing acute kidney failure (AKF) involves a comprehensive evaluation, including a combination of laboratory tests and clinical assessment. A crucial step in the diagnosis is measuring the patient’s serum creatinine levels, which provides insights into their glomerular filtration rate (GFR). Reduced GFR is a hallmark of AKF, indicating impaired kidney function.
In addition to creatinine testing, healthcare providers may order other diagnostic tests to determine the underlying cause of the kidney failure. These can include:
- Urine output monitoring: Measuring the patient’s urine volume and characteristics can reveal patterns associated with different types of AKF.
- Kidney biopsy: In some cases, a small sample of kidney tissue may be obtained through a minimally invasive procedure to examine the cellular and structural changes within the kidneys.
- Imaging studies: Techniques like ultrasound or CT scans can help evaluate the kidneys and identify potential obstructions or other anatomical abnormalities.
The combination of these diagnostic tests and procedures allows healthcare providers to not only diagnose AKF but also classify the condition based on its severity and underlying etiology. This information is crucial in guiding appropriate treatment interventions and monitoring the patient’s progress.
| Diagnostic Test | Purpose | Significance |
|---|---|---|
| Serum Creatinine | Measure kidney function | Elevated creatinine levels indicate impaired glomerular filtration rate (GFR) |
| Urine Output Monitoring | Assess kidney function and identify patterns | Decreased urine output is a hallmark of acute kidney failure |
| Kidney Biopsy | Examine kidney tissue for underlying cause | Provides insights into the cellular and structural changes within the kidneys |
| Imaging Studies (Ultrasound, CT Scan) | Evaluate kidney anatomy and identify abnormalities | Helps rule out obstructions or other structural issues contributing to kidney failure |
“Early and accurate diagnosis of acute kidney failure is crucial for initiating appropriate treatment and monitoring the patient’s progress.”
Treatment Options
When it comes to treating acute kidney failure, the approach often depends on the underlying cause and the severity of the condition. The initial management typically involves optimizing fluid and electrolyte balance, addressing any underlying medical conditions, and providing supportive care.
One of the crucial aspects of treatment is fluid management. Healthcare professionals carefully monitor and adjust fluid intake and output to maintain the proper balance and prevent complications like fluid overload or dehydration. Medications may also be used to manage issues like hyperkalemia (high potassium levels) or metabolic acidosis.
In more severe cases of acute kidney failure, renal replacement therapy may be necessary. This can include hemodialysis or continuous renal replacement therapy (CRRT), which temporarily replace the kidney’s filtering function and help restore the body’s fluid and electrolyte balance.
Supportive care, such as monitoring vital signs, providing nutrition, and managing any underlying conditions, is also an essential part of the treatment approach. The goal is to address the root cause of the acute kidney failure and support the body’s natural healing processes.
| Treatment Approach | Description |
|---|---|
| Fluid Management | Careful monitoring and adjustment of fluid intake and output to maintain balance and prevent complications. |
| Medications | Used to manage issues like hyperkalemia (high potassium levels) or metabolic acidosis. |
| Renal Replacement Therapy | Hemodialysis or continuous renal replacement therapy (CRRT) to temporarily replace kidney function. |
| Supportive Care | Monitoring vital signs, providing nutrition, and managing underlying conditions. |
The key to successful treatment for acute kidney failure is a comprehensive, personalized approach that addresses the underlying cause, supports the body’s natural healing processes, and mitigates the risk of complications.

Complications and Prognosis
Acute kidney failure can lead to a range of complications that require prompt recognition and management. These complications can include fluid overload, electrolyte imbalances, metabolic acidosis, and an increased risk of infections. The prognosis for acute kidney failure depends on the underlying cause, the severity of the condition, and the overall health status of the patient.
One key factor influencing the prognosis is the mortality rate associated with acute kidney failure. Studies have shown that the mortality rate can be high, particularly in the presence of comorbidities or when the condition is not recognized and treated early on. However, with timely intervention and appropriate treatment, many patients can recover kidney function, although some may develop chronic kidney disease as a long-term outcome.
| Complication | Description | Impact on Prognosis |
|---|---|---|
| Fluid Overload | Inability to properly regulate fluid balance, leading to swelling and pulmonary edema | Increases risk of respiratory distress and cardiovascular complications |
| Electrolyte Imbalances | Disruption in the balance of essential minerals like sodium, potassium, and calcium | Can lead to arrhythmias, muscle weakness, and neurological symptoms |
| Metabolic Acidosis | Accumulation of acids in the body due to impaired kidney function | Contributes to organ dysfunction and increases the risk of complications |
| Increased Infection Risk | Weakened immune system and impaired ability to clear infections | Raises the risk of sepsis and other life-threatening infections |
Early recognition and appropriate treatment are crucial in managing the complications of acute kidney failure and improving the overall prognosis for patients. Ongoing monitoring and close collaboration between healthcare providers and patients are essential to ensure the best possible outcomes.
“Prompt recognition and management of acute kidney failure are critical to preventing life-threatening complications and improving patient outcomes.”
Prevention Strategies
Preventing acute kidney failure requires a multifaceted approach, encompassing both lifestyle modifications and medical management. By addressing the underlying factors that can lead to acute renal failure, healthcare providers and patients can work together to minimize the risk of this serious.
Lifestyle Modifications
Maintaining proper hydration is a crucial step in preventing acute kidney failure. Drinking adequate amounts of water throughout the day can help to support healthy kidney function and reduce the risk of dehydration, which can contribute to acute kidney injury. Additionally, limiting the intake of alcohol and avoiding excessive use of over-the-counter medications can help to protect the kidneys from potential damage.
Medical Management
From a medical perspective, healthcare providers can play a vital role in preventing acute kidney failure. This includes carefully managing medications, particularly for patients at higher risk of kidney function decline. Providers may adjust the dosages of potentially nephrotoxic drugs and closely monitor patients receiving contrast dyes to minimize the risk of acute kidney injury. Prompt recognition and treatment of underlying conditions, such as diabetes and hypertension, are also essential prevention strategies.

Acute Kidney Injury Classification
Acute kidney injury (AKI) is a critical medical condition that requires prompt identification and management. To standardize the classification and assessment of AKI, healthcare professionals often utilize the RIFLE (Risk, Injury, Failure, Loss, End-stage kidney disease) and AKIN (Acute Kidney Injury Network) criteria.
RIFLE Criteria
The RIFLE criteria define the stages of AKI based on changes in serum creatinine and urine output. The stages are as follows:
- Risk: Increase in serum creatinine by 1.5 times or decrease in urine output to less than 0.5 mL/kg/h for 6 hours.
- Injury: Increase in serum creatinine by 2 times or decrease in urine output to less than 0.5 mL/kg/h for 12 hours.
- Failure: Increase in serum creatinine by 3 times or decrease in urine output to less than 0.3 mL/kg/h for 24 hours or anuria for 12 hours.
- Loss: Persistent acute renal failure, complete loss of kidney function for more than 4 weeks.
- End-stage kidney disease: End-stage kidney disease for more than 3 months.
AKIN Criteria
The AKIN criteria, on the other hand, classify AKI into three stages based on changes in serum creatinine and urine output:
- Stage 1: Increase in serum creatinine by 0.3 mg/dL or increase to 1.5-2 times the baseline level, or urine output less than 0.5 mL/kg/h for 6 hours.
- Stage 2: Increase in serum creatinine to 2-3 times the baseline level or urine output less than 0.5 mL/kg/h for 12 hours.
- Stage 3: Increase in serum creatinine to 3 times the baseline level or more, or serum creatinine of 4 mg/dL or more with an acute increase of at least 0.5 mg/dL, or urine output less than 0.3 mL/kg/h for 24 hours or anuria for 12 hours.
These classification systems provide a standardized approach to assessing the severity of acute kidney injury, which is crucial in guiding treatment and predicting prognosis. By applying the RIFLE or AKIN criteria, healthcare providers can better manage patients with acute kidney injury and improve patient outcomes.
According to the provided statistics, acute kidney injury (AKI) can be seen in up to 7% of hospital admissions and 30% of ICU admissions. The incidence rate of AKI during hospitalization is estimated to be between 2% and 5%. Accurate classification of AKI using the RIFLE and AKIN criteria is essential for effective management and improved patient outcomes.
