Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Glomerular diseases
      (N00-N08)
      • Nephrotic syndrome
        (N04)

N04.2 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of nephrotic syndrome with diffuse membranous glomerulonephritis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Nephrotic syndrome w diffuse membranous glomerulonephritis

Non-specific codes like N04.2 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for nephrotic syndrome w diffuse membranous glomerulonephritis:

  • Use N04.20 for Nephrotic syndrome with diffuse membranous glomerulonephritis, unspecified - BILLABLE CODE

  • Use N04.21 for Primary membranous nephropathy with nephrotic syndrome - BILLABLE CODE

  • Use N04.22 for Secondary membranous nephropathy with nephrotic syndrome - BILLABLE CODE

  • Use N04.29 for Other nephrotic syndrome with diffuse membranous glomerulonephritis - BILLABLE CODE

Clinical Classification

Clinical Information

  • Nephrosis, Lipoid

    a kidney disease with no or minimal histological glomerular changes on light microscopy and with no immune deposits. it is characterized by lipid accumulation in the epithelial cells of kidney tubules and in the urine. patients usually show nephrotic syndrome indicating the presence of proteinuria with accompanying edema.
  • Nephrotic Syndrome

    a condition characterized by severe proteinuria, greater than 3.5 g/day in an average adult. the substantial loss of protein in the urine results in complications such as hypoproteinemia; generalized edema; hypertension; and hyperlipidemias. diseases associated with nephrotic syndrome generally cause chronic kidney dysfunction.

New 2024 ICD-10-CM Code

N04.2 is new to ICD-10-CM code set for the FY 2024, effective October 1, 2023. The National Center for Health Statistics (NCHS) has published an update to the ICD-10-CM diagnosis codes which became effective October 1, 2023. This is a new and revised code for the FY 2024 (October 1, 2023 - September 30, 2024).

Replaced Code

This code was replaced in the 2024 ICD-10-CM code set with the code(s) listed below. The National Center for Health Statistics (NCHS) has published an update to the ICD-10-CM diagnosis codes which became effective October 1, 2023. This code was replaced for the FY 2024 (October 1, 2023 - September 30, 2024).


  • N04.20 - Nephrotic syndrome with diffuse membranous glomrlneph, unsp
  • N04.21 - Primary membranous nephropathy with nephrotic syndrome
  • N04.22 - Secondary membranous nephropathy with nephrotic syndrome
  • N04.29 - Other nephrotic syndrome with diffuse membranous glomrlneph

Convert N04.2 to ICD-9-CM

  • ICD-9-CM Code: 581.1 - Epimembranous nephritis
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.

Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include:

  • Cancer
  • Cysts
  • Stones
  • Infections

Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.
