2025 ICD-10-CM code N08
(Active) Effective Date: N/A Diseases of the genitourinary system - Glomerular diseases (N00-N08) Diseases of the genitourinary system (N00-N99) Feed
Glomerular disorders in diseases classified elsewhere.Includes glomerulonephritis, nephritis, and nephropathy.
Medical necessity is established by the diagnosis of the underlying disease and the associated glomerular disorder.The documentation should support the need for treatment and management of both conditions.
The clinician is responsible for diagnosing the underlying condition causing the glomerular disorder and coding it first, followed by code N08. They should also document the type of glomerular disorder and any associated kidney failure.
In simple words: This code represents a kidney problem (glomerular disorder) that occurs as part of another disease.The other disease is the main cause and needs to be coded first.
Glomerular disorders in diseases classified elsewhere. Code first the 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).
Example 1: A patient with multiple myeloma develops nephrotic syndrome. Code C90.0- (Multiple myeloma) and N08 (Glomerular disorders in diseases classified elsewhere)., A patient with gout presents with acute glomerulonephritis. Code M1A.- or M10.- (Gout) and N08., A patient with amyloidosis is found to have chronic glomerulonephritis. Code E85.- (Amyloidosis) and N08.
Documentation should include the underlying disease, the type of glomerular disorder (e.g., acute glomerulonephritis, nephrotic syndrome, chronic glomerulonephritis), and any associated kidney failure.
** Excludes1: glomerulonephritis, nephritis, and nephropathy in: antiglomerular basement membrane disease (M31.0), diabetes (E08-E13 with .21), 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). Excludes2: certain conditions originating in the perinatal period (P04-P96), certain infectious and parasitic diseases (A00-B99), complications of pregnancy, childbirth and the puerperium (O00-O9A), congenital malformations, deformations and chromosomal abnormalities (Q00-Q99), endocrine, nutritional and metabolic diseases (E00-E88), injury, poisoning and certain other consequences of external causes (S00-T88), neoplasms (C00-D49), symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94).Use additional code to identify manifestation.
