N03.8
Chronic nephritic syndrome with other morphologic changes
Clinical Classification Guidelines
Inclusion Terms
- Chronic nephritic syndrome with proliferative glomerulonephritis NOS
Medical Intelligence & Overview
Chronic nephritic syndrome with other morphologic changes is a kidney condition characterized by long-term inflammation of the glomeruli, the tiny filtering units within the kidneys. This condition, coded as N03.8 in the ICD-10 classification, often involves additional structural changes in the kidneys, leading to impaired kidney function over time. It manifests with a combination of symptoms and underlying pathological changes, typically requiring careful diagnosis and management to prevent further kidney damage.
Causes & Symptoms
Clinical Causes: Autoimmune diseases, such as lupus erythematosus, which cause the body's immune system to attack the kidneys. Infections that trigger immune responses, leading to inflammation of the glomeruli. Certain medications or substances that can induce kidney inflammation. Chronic hypertension (high blood pressure), which damages blood vessels in the kidneys. Other underlying kidney diseases that progress to involve glomerular inflammation.
Key Symptoms: Blood in the urine (hematuria), making it appear reddish or brownish. Protein in the urine (proteinuria), which may cause foamy urine. Swelling (edema) around the eyes, hands, feet, or abdomen due to fluid retention. High blood pressure resulting from impaired kidney function. Reduced urine output or abnormal urine appearance. Fatigue and weakness caused by buildup of waste products in the blood. Possible signs of uncontrolled inflammation, such as fever or malaise.
Diagnostic & Treatment
Diagnosis Path: Urinalysis to detect blood and protein in the urine. Blood tests to assess kidney function (creatinine, blood urea nitrogen) and detect signs of inflammation. Imaging studies like ultrasound to evaluate kidney size and structure. Kidney biopsy, which involves obtaining a small sample of kidney tissue for microscopic examination, to identify specific morphological changes and confirm proliferative glomerulonephritis. Serological tests to look for underlying autoimmune conditions or infections.
Treatment Protocols: Use of corticosteroids or other immunosuppressive medications to reduce immune system activity and inflammation. Blood pressure control with antihypertensive drugs, such as ACE inhibitors or ARBs, which also help reduce proteinuria. Dietary modifications, including reduced salt intake and limiting protein consumption as advised by healthcare providers. Management of edema with diuretics to help remove excess fluid. Treatment of underlying infections or autoimmune conditions contributing to kidney inflammation. Regular monitoring of kidney function and urine analysis to track disease progression.

Is N03.8 a billable ICD-10 code?
Yes, N03.8 is a specific, billable code that can be used to indicate a diagnosis for reimbursement purposes.
Documentation
How do I report N03.8?
Clinical documentation must specify the nature of Chronic nephritic syndrome with other morphologic changes and any associated comorbidities for accurate reporting.
