Acute Renal Failure ICD-10-CM Codes

What ICD-10 Codes are Used for Acute Renal Failure?

Acute Renal Failure, also known as acute kidney injury, is a serious condition characterized by a sudden decline in kidney function. The ICD-10-CM codes used to classify this condition are essential for accurate medical billing and documentation. 

Below are 8 commonly used codes for Acute Renal Failure:

N17.0 - Acute kidney failure with tubular necrosis: This code is used when acute kidney failure is caused by tubular necrosis, often due to ischemia or nephrotoxic agents.

N17.1 - Acute kidney failure with acute cortical necrosis: This code is used when acute kidney failure is caused by acute cortical necrosis, typically from severe ischemia or vascular disorders.

N17.2 - Acute kidney failure with medullary necrosis: This code is used when acute kidney failure is caused by medullary necrosis, often resulting from sickle cell disease or ischemic injury.

N17.8 - Other acute kidney failure: This code covers cases of acute renal failure not falling into the previously mentioned categories.

N17.9 - Acute kidney failure, unspecified: This code is used when specific details about the cause of acute kidney failure are unavailable or not documented.

N99.0 - Postprocedural (acute) (transient) renal failure: This code is used when acute renal failure occurs as a complication of a medical procedure.

N27.0 - Small kidney, unilateral: This code is used when a patient has a congenitally small kidney on one side, which may predispose them to acute kidney failure.

R34.0 - Anuria: This code is used when there is a complete absence of urine output, a serious sign of acute renal failure.

Which Acute Renal Failure ICD codes are Billable?

The following ICD-10-CM codes for Acute Renal Failure are billable:

N17.0 - Yes, billable: Reimbursement is available for cases of acute kidney failure with tubular necrosis when documented appropriately.

N17.1 - Yes, billable: Cases of acute kidney failure with acute cortical necrosis are eligible for reimbursement upon accurate coding.

N17.2 - Yes, billable: Reimbursement is applicable for acute kidney failure cases with medullary necrosis, provided the documentation is precise.

N17.8 - Yes, billable: Other specific types of acute kidney failure can be billed with this code when supported by medical records.

N17.9 - Yes, billable: Acute kidney failure cases lacking detailed information can still be billed under this unspecified code.

N99.0 - Yes, billable: Acute renal failure arising as a postprocedural complication is eligible for reimbursement.

N27.0 - No, not billable: This code denotes a congenital condition and is not billable for acute kidney failure alone.

R34.0 - No, not billable: Code R34.0 represents anuria, a symptom of acute renal failure, but it is not eligible for billing.

Clinical Information

• Acute renal failure (ARF), also known as acute kidney injury (AKI), is a sudden and severe loss of kidney function.
• Common causes include severe dehydration, kidney infections, drug toxicity, and reduced blood flow to the kidneys.
• Symptoms may include decreased urine output, fluid retention, fatigue, confusion, and electrolyte imbalances.
• Diagnosis is based on blood and urine tests to assess kidney function and identify the underlying cause.
• Treatment focuses on addressing the underlying cause, supporting kidney function, and managing complications.
• In severe cases, temporary dialysis may be necessary to assist kidney function until recovery occurs.
• ARF requires close monitoring and prompt medical intervention to prevent further kidney damage.
• The prognosis of ARF varies depending on the cause, severity, and timeliness of treatment.
• Early recognition and management of risk factors can help prevent acute renal failure in some cases.

• Acute Renal Insufficiency

• Abrupt Renal Impairment
• Acute Kidney Damage
