Chronic nephritic syndrome with minor glomerular abnormality

This code signifies a persistent inflammatory condition of the kidney's filtering units (glomeruli) characterized by microscopic changes that are not severe. It indicates a chronic form of glomerulonephritis where the primary pathology involves minimal alterations to the glomerular structure, often detected through renal biopsy. Patients typically present with proteinuria, hematuria, and sometimes hypertension or edema.

Apply this code when documentation confirms a chronic nephritic syndrome and a renal biopsy report or nephrologist's assessment specifically identifies "minor glomerular abnormality" or "minimal change disease" as the underlying cause. This diagnosis is typically made after excluding other forms of glomerulonephritis with more significant histological findings.

• Ensure documentation explicitly states "chronic" and "minor glomerular abnormality" or similar terminology.
• Do not confuse this with acute nephritic syndromes or other specific types of chronic glomerulonephritis with distinct histological classifications.
• Code any associated manifestations, such as chronic kidney disease (CKD), hypertension, or edema, as secondary diagnoses.
