2024 ICD-10-CM Diagnosis Code N28.9
Disorder of kidney and ureter, unspecified
- ICD-10-CM:
- N28.9
- Short Description:
- Disorder of kidney and ureter, unspecified
- Is Billable?
- Yes - Valid for Submission
- Code Navigator:
N28.9 is a billable diagnosis code used to specify a medical diagnosis of disorder of kidney and ureter, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
Unspecified diagnosis codes like N28.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information
- Azotemia-. a biochemical abnormality referring to an elevation of blood urea nitrogen and creatinine. azotemia can be produced by kidney diseases or other extrarenal disorders. when azotemia becomes associated with a constellation of clinical signs, it is termed uremia.
- Acute Kidney Injury-. abrupt reduction in kidney function. acute kidney injury encompasses the entire spectrum of the syndrome including acute kidney failure; acute kidney tubular necrosis; and other less severe conditions.
- Renal Insufficiency-. conditions in which the kidneys perform below the normal level in the ability to remove wastes, concentrate urine, and maintain electrolyte balance; blood pressure; and calcium metabolism. renal insufficiency can be classified by the degree of kidney damage (as measured by the level of proteinuria) and reduction in glomerular filtration rate.
- Renal Insufficiency, Chronic-. conditions in which the kidneys perform below the normal level for more than three months. chronic kidney insufficiency is classified by five stages according to the decline in glomerular filtration rate and the degree of kidney damage (as measured by the level of proteinuria). the most severe form is the end-stage renal disease (chronic kidney failure). (kidney foundation: kidney disease outcome quality initiative, 2002)
- Anasarca-. a condition that is characterized by the presence of generalized edema. causes include congestive heart failure, liver failure, renal failure, and severe malnutrition.
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Nephropathy NOS
- Renal disease (acute) NOS
- Renal insufficiency (acute)
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Patient Education
Kidney Diseases
You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes 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 have a higher risk of 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 do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.

Ureteral Disorders
Your kidneys make urine by filtering wastes and extra water from your blood. The urine travels from the kidneys to the bladder in two thin tubes called ureters.
The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.
Sometimes the ureters can become blocked or injured. This can block the flow of urine to the bladder. If urine stands still or backs up the ureter, you may get a urinary tract infections.
Doctors diagnose problems with the ureters using different tests. These include urine tests, x-rays, and examination of the ureter with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.
