Glomerular disorders in diseases classified elsewhere
Chapter 14:Diseases of the genitourinary system
ICD-10 N08 is a billable code used to indicate a diagnosis of glomerular disorders in diseases classified elsewhere.
N08 encompasses a range of glomerular disorders that are secondary to systemic diseases or conditions classified elsewhere in the ICD-10 system. These disorders can manifest as isolated proteinuria, hereditary nephropathy, or other glomerular pathologies resulting from underlying diseases such as diabetes mellitus, systemic lupus erythematosus, or hypertension. Isolated proteinuria, often a key indicator of glomerular dysfunction, may arise from various etiologies, including genetic predispositions or environmental factors. Hereditary nephropathies, such as Alport syndrome, are characterized by genetic mutations affecting the glomerular filtration barrier, leading to progressive kidney disease. Accurate coding of N08 requires a thorough understanding of the underlying conditions contributing to the glomerular disorder, as well as the clinical implications of these associations. Clinicians must provide detailed documentation of the primary disease process, the nature of the glomerular involvement, and any relevant genetic testing results to ensure appropriate coding and reimbursement.
Detailed history of renal function, results of urinalysis, and any genetic testing performed.
Patients with diabetes presenting with proteinuria, hereditary nephropathy cases, or patients with systemic diseases showing renal involvement.
Ensure that the primary disease is clearly documented and linked to the glomerular disorder.
Results of genetic testing, family history of renal disease, and clinical correlation of genetic findings.
Patients with a family history of nephropathy or those presenting with atypical renal symptoms.
Documentation must clearly connect genetic findings to the clinical presentation of glomerular disorders.
Used to evaluate proteinuria in patients suspected of glomerular disorders.
Document the reason for urinalysis and any relevant clinical findings.
Nephrologists should correlate urinalysis results with clinical findings.
Use N08 when the glomerular disorder is secondary to another disease, such as diabetes or lupus, and not primarily due to glomerulonephritis.
