2021 ICD-10-CM Code N29
Other disorders of kidney and ureter in diseases classified elsewhere
Valid for Submission
N29 is a billable diagnosis code used to specify a medical diagnosis of other disorders of kidney and ureter in diseases classified elsewhere. The code N29 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code N29 might also be used to specify conditions or terms like cortical nephrocalcinosis, disorder of kidney and/or ureter caused by schistosoma haematobium, disorder of kidney due to lambda light chain disease, enamel-renal syndrome, familial hypomagnesemia hypercalciuria nephrocalcinosis with severe ocular involvement , familial hypomagnesemia-hypercalciuria, etc.

Code Classification
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code N29:
Code First
Code FirstCertain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
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.
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code N29 are found in the index:
- - Calcification
- - kidney - N28.89
- - tuberculous - N29
- - kidney - N28.89
Code Edits
The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10 Code Edits are applicable to this code:
- Manifestation diagnoses - Manifestation codes describe the manifestation of an underlying disease, not the disease itself, and therefore should not be used as a principal diagnosis.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Cortical nephrocalcinosis
- Disorder of kidney and/or ureter caused by Schistosoma haematobium
- Disorder of kidney due to lambda light chain disease
- Enamel-renal syndrome
- Familial hypomagnesemia hypercalciuria nephrocalcinosis with severe ocular involvement
- Familial hypomagnesemia-hypercalciuria
- Familial hypomagnesemia-hypercalciuria
- Familial primary hypomagnesemia with hypercalciuria and nephrocalcinosis without severe ocular involvement

- Renal involvement in malignant disease
- Renal involvement in scleroderma
- Schistosoma haematobium infection
- T3 : Tumor of uterine cervix extends to the pelvic wall and/or involves the lower third of the vagina and/or causes hydronephrosis or nonfunctioning kidney
- T3b : Tumor of uterine cervix extends to pelvic wall and/or causes hydronephrosis or nonfunctioning kidney

Diagnostic Related Groups - MS-DRG Mapping
The ICD-10 code N29 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2021.
Convert N29 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code N29 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Kidney Diseases
Also called: Renal disease
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.
