ICD-10-CM Code N06

Isolated proteinuria with specified morphological lesion

Version 2020 Non-Billable Code

Not Valid for Submission

N06 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of isolated proteinuria with specified morphological lesion. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

ICD-10:N06
Short Description:Isolated proteinuria with specified morphological lesion
Long Description:Isolated proteinuria with specified morphological lesion

Consider the following ICD-10 codes with a higher level of specificity:

  • N06.0 - Isolated proteinuria with minor glomerular abnormality
  • N06.1 - Isolated proteinuria with focal and segmental glomerular lesions
  • N06.2 - Isolated proteinuria with diffuse membranous glomerulonephritis
  • N06.3 - Isolated proteinuria with diffuse mesangial proliferative glomerulonephritis
  • N06.4 - Isolated proteinuria with diffuse endocapillary proliferative glomerulonephritis
  • N06.5 - Isolated proteinuria with diffuse mesangiocapillary glomerulonephritis
  • N06.6 - Isolated proteinuria with dense deposit disease
  • N06.7 - Isolated proteinuria with diffuse crescentic glomerulonephritis
  • N06.8 - Isolated proteinuria with other morphologic lesion
  • N06.9 - Isolated proteinuria with unspecified morphologic lesion

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code N06:

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.
  • Proteinuria not associated with specific morphologic lesions R80.0

Code Classification

  • Diseases of the genitourinary system (N00–N99)
    • Glomerular diseases (N00-N08)
      • Isolated proteinuria with specified morphological lesion (N06)

Information for Patients


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.

Urine and Urination

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate. It swells into a round shape when it is full and gets smaller when empty. If your urinary system is healthy, your bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.

You may have problems with urination if you have

  • Kidney failure
  • Urinary tract infections
  • An enlarged prostate
  • Bladder control problems like incontinence, overactive bladder, or interstitial cystitis
  • A blockage that prevents you from emptying your bladder

Some conditions may also cause you to have blood or protein in your urine. If you have a urinary problem, see your health care provider. Urinalysis and other urine tests can help to diagnose the problem. Treatment depends on the cause.
