Acute Kidney Injury ICD-10-CM Codes

What ICD-10 Codes are Used for Acute Kidney Injury (AKI)?

Acute Kidney Injury (AKI), commonly known as acute renal failure, refers to the abrupt loss of kidney function. Accurate ICD-10-CM codes are essential for medical billing and documentation. Below are 7 commonly used codes for AKI:

N17.0 - Acute kidney failure with tubular necrosis: AKI caused by tubular necrosis, often due to ischemia or nephrotoxic agents.

N17.1 - Acute kidney failure with acute cortical necrosis: AKI caused by acute cortical necrosis, typically arising from severe ischemia or vascular disorders.

N17.2 - Acute kidney failure with medullary necrosis: AKI caused by medullary necrosis, often resulting from sickle cell disease or ischemic injury.

N17.8 - Other acute kidney failure: This code covers cases of AKI not classified under the previously mentioned codes.

N17.9 - Acute kidney failure, unspecified: Used when specific details about the cause of AKI are unavailable or documented.

N99.0 - Postprocedural (acute) (transient) renal failure: AKI occurring as a complication of a medical procedure.

R34.0 - Anuria: Denotes complete absence of urine output, which can be a symptom of AKI.

Which AKI ICD codes are Billable?

The following ICD-10-CM codes for Acute Kidney Injury (AKI) are billable:

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

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

N17.2 - Yes, billable: Reimbursement applies to AKI cases with medullary necrosis, provided the documentation is precise.

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

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

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

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

Clinical Information

• A sudden and rapid decline in kidney function is known as acute kidney injury (AKI) or acute renal failure.
• Dehydration, kidney infections, urinary tract obstructions, medications, and illnesses that affect the kidneys' ability to receive blood flow are common causes.
• Reduced urine output, swelling, fatigue, confusion, and nausea are a few symptoms that may be present.
• Blood and urine tests diagnose kidney disease and identify its underlying cause.
• Depending on where the issue is, AKI can be divided into three stages: prerenal, intrinsic renal, and postrenal.
• The goal of treatment is to manage complications, support kidney function, and deal with the underlying cause.
• In extreme circumstances, temporary dialysis may be needed to support kidney function while the patient recovers.
• AKI necessitates careful observation and prompt treatment to stop further kidney damage.
• The cause, severity, and promptness of treatment all affect the prognosis.
• Examples of preventive measures include managing risk factors, staying hydrated, and using medications cautiously while under a doctor's care.
