Code Classification

  • Diseases of the genitourinary system
    (N00–N99)
    • Glomerular diseases
      (N00-N08)
      • Unspecified nephritic syndrome
        (N05)

N05 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of unspecified nephritic syndrome. 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.

Unspecified diagnosis codes like N05 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding Applicable to Unspecified nephritic syndrome

Non-specific codes like N05 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 unspecified nephritic syndrome:

  • Use N05.0 for Unspecified nephritic syndrome with minor glomerular abnormality - BILLABLE CODE

  • Use N05.1 for Unspecified nephritic syndrome with focal and segmental glomerular lesions - BILLABLE CODE

  • Use N05.2 for Unspecified nephritic syndrome with diffuse membranous glomerulonephritis - BILLABLE CODE

  • Use N05.3 for Unspecified nephritic syndrome with diffuse mesangial proliferative glomerulonephritis - BILLABLE CODE

  • Use N05.4 for Unspecified nephritic syndrome with diffuse endocapillary proliferative glomerulonephritis - BILLABLE CODE

  • Use N05.5 for Unspecified nephritic syndrome with diffuse mesangiocapillary glomerulonephritis - BILLABLE CODE

  • Use N05.6 for Unspecified nephritic syndrome with dense deposit disease - BILLABLE CODE

  • Use N05.7 for Unspecified nephritic syndrome with diffuse crescentic glomerulonephritis - BILLABLE CODE

  • Use N05.8 for Unspecified nephritic syndrome with other morphologic changes - BILLABLE CODE

  • Use N05.9 for Unspecified nephritic syndrome with unspecified morphologic changes - BILLABLE CODE

  • Use N05.A for Unspecified nephritic syndrome with C3 glomerulonephritis - BILLABLE CODE

Clinical Information

  • Nephritic Syndrome

    a syndrome characterized by hematuria with dysmorphic red blood cells, red blood cell casts, and proteinuria; systemic manifestations may be present, including hypertension, edema, oliguria.

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Includes

Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • glomerular disease NOS
  • glomerulonephritis NOS
  • nephritis NOS
  • nephropathy NOS and renal disease NOS with morphological lesion specified in .0-.8

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • nephropathy NOS with no stated morphological lesion N28.9
  • renal disease NOS with no stated morphological lesion N28.9
  • tubulo-interstitial nephritis NOS N12

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.
