Renal Insufficiency ICD-10-CM Codes

What ICD-10 Codes are Used for Renal Insufficiency 

Renal insufficiency, characterized by impaired kidney function, necessitates accurate diagnosis and coding for effective treatment and management. The International Classification of Diseases, Tenth Revision (ICD-10), provides standardized codes to classify and identify various renal insufficiency disorders.

Here are the commonly used Renal Insufficiency ICD Codes:

N18.9 - Chronic kidney disease (CKD), unspecified:

N18.9 is a general code used when the specific type or chronic kidney disease stage is not documented. It signifies the presence of long-term kidney damage and impaired kidney function.

N19 - Unspecified kidney failure:

N19 is assigned when there is a lack of detailed information regarding the specific cause or stage of kidney failure. It represents a broad category encompassing acute or chronic kidney failure of unspecified etiology.

N17.9 - Acute kidney failure, unspecified:

N17.9 is used when acute kidney failure is diagnosed, but the specific cause or type is not specified. Acute kidney failure occurs suddenly and is characterized by a rapid decline in kidney function, resulting in impaired waste removal and fluid balance.

N28.9 - Disorder of kidney and ureter, unspecified:

N28.9 represents a general code for unspecified disorders affecting the kidney and ureter. It includes conditions like renal colic or unspecified kidney damage without further specification.

N28.0 - Ischemia and infarction of kidney:

N28.0 is assigned when the kidney is diagnosed with ischemia (inadequate blood supply) or infarction (tissue death due to lack of blood flow). This code indicates a potentially severe condition that may lead to renal insufficiency.

N25.9 - Disorder resulting from impaired renal tubular function, unspecified:

N25.9 is used when there is a disorder resulting from impaired renal tubular function without specifying the exact nature of the disorder. It encompasses conditions like tubular acidosis or renal tubular defects.

N18.1 - Chronic kidney disease, stage 1:

N18.1 represents the first stage of chronic kidney disease, characterized by kidney damage with a normal or increased glomerular filtration rate (GFR). It signifies early kidney dysfunction and requires close monitoring and management.

N17.0 - Acute kidney failure with tubular necrosis:

N17.0 is assigned when acute kidney failure occurs due to tubular necrosis, typically caused by ischemia or nephrotoxic substances. This code highlights a specific cause of acute kidney injury.

N25.0 - Renal osteodystrophy:

N25.0 denotes a condition characterized by bone abnormalities associated with chronic kidney disease. It includes bone loss, mineral imbalances, and skeletal deformities due to impaired mineral metabolism.

N18.4 - Chronic kidney disease, stage 4:

N18.4 represents the fourth chronic kidney disease stage, indicating severe kidney damage with a significantly reduced GFR. This stage requires advanced medical intervention, including dialysis or transplantation.

Which Renal Insufficiency  ICD codes are Billable:

N18.9 - Chronic kidney disease (CKD), unspecified

Yes, this code is billable as it represents a specific diagnosis of chronic kidney disease without further specification, allowing for appropriate billing and reimbursement.

N19 - Unspecified kidney failure

Yes, this code is billable as it signifies a diagnosis of unspecified kidney failure, providing the necessary information for billing purposes.

N17.9 - Acute kidney failure, unspecified

Yes, this code is billable as it indicates a diagnosis of acute kidney failure without specifying the cause, allowing for appropriate billing and reimbursement.

N28.9 - Disorder of kidney and ureter, unspecified

This code is billable as it denotes a diagnosis of an unspecified disorder affecting the kidney and ureter, enabling proper billing and reimbursement.

N28.0 - Ischemia and infarction of kidney

Yes, this code is billable as it represents a specific diagnosis of ischemia or infarction of the kidney, providing the necessary information for billing purposes.

N25.9 - Disorder resulting from impaired renal tubular function, unspecified

Yes, this code is billable as it signifies a diagnosis of a disorder resulting from impaired renal tubular function without specifying the exact nature of the disorder, allowing for appropriate billing and reimbursement.

N18.1 - Chronic kidney disease, stage 1

Yes, this code is billable as it represents a specific stage of chronic kidney disease, enabling proper billing and reimbursement based on the severity of the condition.

N17.0 - Acute kidney failure with tubular necrosis

Yes, this code is billable as it specifies a diagnosis of acute kidney failure with tubular necrosis, providing the necessary information for billing purposes.

N25.0 - Renal osteodystrophy

Yes, this code is billable as it signifies a diagnosis of renal osteodystrophy, allowing for appropriate billing and reimbursement for this specific condition related to renal insufficiency.

N18.4 - Chronic kidney disease, stage 4

Yes, this code is billable as it represents a specific stage of chronic kidney disease, enabling proper billing and reimbursement based on the severity of the condition.

Clinical Information

• Renal insufficiency refers to a condition where the kidneys cannot function optimally, leading to a decline in their ability to filter waste products and maintain fluid and electrolyte balance.
• Common causes of renal insufficiency include chronic kidney disease (CKD), acute kidney injury (AKI), diabetes, hypertension, glomerulonephritis, and certain medications.
• Symptoms of renal insufficiency may include fatigue, weakness, decreased urine output, fluid retention, electrolyte imbalances, and anemia.
• Diagnosis of renal insufficiency involves a combination of medical history, physical examination, laboratory tests (such as serum creatinine, blood urea nitrogen, and glomerular filtration rate), and imaging studies (such as renal ultrasound or CT scan).
• Treatment for renal insufficiency aims to manage the underlying cause, slow disease progression, and alleviate symptoms. This may include lifestyle modifications, medication management, dietary changes (such as restricting sodium and protein intake), dialysis, or kidney transplantation.
• Complications of untreated or poorly managed renal insufficiency can include electrolyte imbalances, fluid overload, cardiovascular disease, anemia, bone disorders, and a higher risk of infections.
• Regular monitoring and follow-up with healthcare providers are essential for individuals with renal insufficiency to manage their condition effectively and prevent complications.
• Collaborative care involving nephrologists, dieticians, pharmacists, and other healthcare professionals is crucial to provide comprehensive treatment and support for patients with renal insufficiency.
• Patient education regarding medication adherence, dietary restrictions, fluid management, and lifestyle modifications is vital for improving outcomes and quality of life in individuals with renal insufficiency.
• Early detection, proactive management, and ongoing medical care significantly optimize kidney function and overall health in patients with renal insufficiency.
