Code Description

ICD-10 N02.5 is a billable code used to indicate a diagnosis of recurrent and persistent hematuria with diffuse mesangiocapillary glomerulonephritis.

Key Diagnostic Point:

N02.5 refers to a condition characterized by recurrent and persistent hematuria, which is the presence of blood in the urine, associated with diffuse mesangiocapillary glomerulonephritis (MCGN). MCGN is a type of kidney disease that affects the glomeruli, the filtering units of the kidneys, leading to inflammation and damage. This condition can result in significant proteinuria, which is the presence of excess protein in the urine, and may progress to nephrotic syndrome, characterized by high levels of proteinuria, low serum albumin, and edema. Patients typically present with symptoms such as hematuria, flank pain, and signs of renal impairment. Renal biopsy findings in MCGN often reveal mesangial proliferation and capillary wall thickening, which are indicative of the underlying pathology. Management of this condition involves addressing the underlying cause, controlling blood pressure, and potentially using immunosuppressive therapy to reduce inflammation and prevent further kidney damage.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Requires understanding of nephrology terminology and conditions.
  • Differentiation from other types of glomerulonephritis.
  • Need for accurate documentation of hematuria and proteinuria.
  • Potential for overlapping symptoms with other renal conditions.

Audit Risk Factors

  • Inadequate documentation of hematuria frequency and severity.
  • Failure to document renal biopsy results.
  • Misclassification of the type of glomerulonephritis.
  • Lack of clear treatment plans in the medical record.
