Patient presents with hematuria, possibly gross hematuria, following an upper respiratory infection or other mucosal infection.  Symptoms consistent with IgA nephropathy include microscopic hematuria, proteinuria, and occasionally hypertension.  Patient may report flank pain, edema, or foamy urine.  Differential diagnosis includes other glomerulonephritis etiologies such as post-infectious glomerulonephritis, thin basement membrane nephropathy, and Alport syndrome.  Laboratory findings reveal elevated serum creatinine and IgA levels.  Urinalysis shows red blood cell casts and proteinuria.  A kidney biopsy was performed confirming the diagnosis of IgA nephropathy, showing mesangial IgA deposits on immunofluorescence microscopy.  The patient's estimated glomerular filtration rate (eGFR) was calculated to assess kidney function.  Treatment plan includes blood pressure control with angiotensin-converting enzyme inhibitors (ACE inhibitors) or angiotensin receptor blockers (ARBs) to reduce proteinuria and slow disease progression.  Patient education provided regarding lifestyle modifications, including dietary sodium restriction and smoking cessation, for renal health management.  Follow-up appointments scheduled for monitoring of kidney function, proteinuria, and blood pressure.  ICD-10 code N08.1 for IgA nephropathy documented.  Medical billing codes for renal biopsy, urinalysis, and other relevant procedures will be submitted.  Patient advised to seek immediate medical attention for any signs of worsening kidney function or complications such as acute kidney injury.
