ICD-10-CM Code N08

Glomerular disorders in diseases classified elsewhere

Version 2020 Billable Code Manifestation Diagnoses

Valid for Submission

N08 is a billable code used to specify a medical diagnosis of glomerular disorders in diseases classified elsewhere. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code N08 might also be used to specify conditions or terms like chronic glomerulonephritis associated with another disorder, cryoglobulinemic glomerulonephritis, glomerular disorder due to non-neuropathic heredofamilial amyloidosis, glomerular disorders in blood diseases and disorders involving the immune mechanism, glomerular disorders in neoplastic diseases, glomerulonephritis co-occurrent and due to antineutrophil cytoplasmic antibody positive vasculitis, etc

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 N08:

Inclusion Terms

Inclusion Terms
These 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.
  • Glomerulonephritis
  • Nephritis
  • Nephropathy

Code First

Code First
Certain 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 Excludes
A 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.
  • glomerulonephritis, nephritis and nephropathy (in):
  • antiglomerular basement membrane disease M31.0
  • diabetes E08 E13

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.


The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Chronic glomerulonephritis associated with another disorder
  • Cryoglobulinemic glomerulonephritis
  • Glomerular disorder due to non-neuropathic heredofamilial amyloidosis
  • Glomerular disorders in blood diseases and disorders involving the immune mechanism
  • Glomerular disorders in neoplastic diseases
  • Glomerulonephritis co-occurrent and due to antineutrophil cytoplasmic antibody positive vasculitis
  • Glomerulonephritis co-occurrent and due to scleroderma
  • Glomerulonephritis due to Henoch-Schönlein purpura
  • Glomerulonephritis due to hepatitis C
  • Henoch-Schönlein nephritis
  • Inborn error of lipoprotein metabolism
  • Juxtaglomerular hyperplasia co-occurrent with secondary hyperaldosteronism
  • Light chain nephropathy
  • Light chain nephropathy due to multiple myeloma
  • Lipoprotein glomerulopathy
  • Macroglobulinemic nephropathy
  • Malignancy-associated glomerulonephritis
  • Malignancy-associated membranous nephropathy
  • Nephrotic syndrome associated with another disorder
  • Renal involvement in malignant disease
  • Renal involvement in malignant disease
  • Renal involvement in malignant disease
  • Renal involvement in scleroderma
  • Secondary hyperaldosteronism
  • Sickle cell nephropathy

Diagnostic Related Groups

The ICD-10 code N08 is grouped in the following groups for version MS-DRG V37.0 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 10/01/2019 through 09/30/2020.

Information for Patients

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.
