- N28.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

- This is the American ICD-10-CM version of N28.9 - other international versions of ICD-10 N28.9 may differ.
Applicable To- Nephropathy NOS
- Renal disease (acute) NOS
- Renal insufficiency (acute)
Type 1 ExcludesType 1 Excludes Help
A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as N28.9. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Information
- A neoplastic or non-neoplastic condition affecting the kidney. Representative examples of non-neoplastic conditions include glomerulonephritis and nephrotic syndrome. Representative examples of neoplastic conditions include benign processes (e.g., renal lipoma and renal fibroma) and malignant processes (e.g., renal cell carcinoma and renal lymphoma).
- A term referring to any disease affecting the kidneys.
- Conditions in which the function of kidneys deteriorates suddenly in a matter of days or even hours. It is characterized by the sudden drop in glomerular filtration rate.
- Impairment of health or a condition of abnormal functioning of the kidney.
- Pathological processes of the kidney or its component tissues.
- Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom. Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You are at greater risk for kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include:
- cancer
- cysts
- stones
- infections
your doctor can run tests to find out if you have kidney disease. If your kidneys fail completely, a kidney transplant or dialysis can replace the work your kidneys normally do.
