Glomerular disorders in diseases classified elsewhere (N08) ICD-10-CM
The N08 code range covers glomerular disorders in diseases classified elsewhere with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
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
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.
- underlying disease, such as:
- amyloidosis E85
- congenital syphilis A50.5
- cryoglobulinemia D89.1
- disseminated intravascular coagulation D65
- gout M1A M10
- microscopic polyangiitis M31.7
- multiple myeloma C90.0
- sepsis A40.0 A41.9
- sickle-cell disease D57.0 D57.8
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
- gonococcal A54.21
- Goodpasture's syndrome M31.0
- hemolytic-uremic syndrome D59.3
- lupus M32.14
- mumps B26.83
- syphilis A52.75
- systemic lupus erythematosus M32.14
- Wegener's granulomatosis M31.31
- pyelonephritis in diseases classified elsewhere N16
- renal tubulo-interstitial disorders classified elsewhere N16

About the N08 Code Range
The ICD-10 code N08 is used to classify glomerular disorders that occur as part of other diseases, rather than as primary kidney conditions. This code helps specify kidney problems that arise secondary to a variety of underlying causes, making it a key tool for accurate diagnosis and coding.
Glomerular disorders in diseases classified elsewhere cover a wide range of conditions where kidney glomeruli are affected due to systemic or external diseases. Common synonyms or related terms include glomerulonephritis linked to antineutrophil cytoplasmic antibody-positive vasculitis, nephritis caused by drugs, and glomerular disease from infectious agents like hepatitis C or parasites such as Schistosoma. It also encompasses conditions like glomerular damage due to hematological disorders, amyloidosis, Fabry disease, sickle cell nephropathy, and neoplastic or mitochondrial diseases. By using the ICD-10 code for glomerular disorders in diseases classified elsewhere, healthcare providers and coders can accurately identify and document complex cases where kidney involvement results from other illnesses, improving clarity in medical records and patient care plans.
