ICD-10 Code for:

Neoplasm of uncertain behavior of kidney

Is Billable?

Not Valid for Submission

Code Navigator:

D41.0 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity from the list below for a diagnosis of neoplasm of uncertain behavior of kidney. The code is not specific and is NOT valid for the year 2026 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.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic kidney (parenchymal) or Neoplasm, neoplastic parenchyma, kidney or Neoplasm, neoplastic renal or Neoplasm, neoplastic renal parenchyma .

Non-specific codes like D41.0 require more digits to indicate the appropriate level of specificity. Consider using any of the following billable codes with a higher level of specificity when coding for neoplasm of uncertain behavior of kidney:

Use D41.00 for Neoplasm of uncertain behavior of unspecified kidney

Use D41.01 for Neoplasm of uncertain behavior of right kidney

Use D41.02 for Neoplasm of uncertain behavior of left kidney

• - Nephroma - C64
  • - mesoblastic - D41.0
• - Reninoma - D41.0
• - Tumor - See Also: Neoplasm, unspecified behavior, by site;
  • - juxtaglomerular - D41.0

References found for this diagnosis code in the External Cause of Injuries Index:

• Nephroma
  • mesoblastic
• Reninoma
• Tumor
  • juxtaglomerular

This code is referenced in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

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.
