ICD-10-CM Code D49.51

Neoplasm of unspecified behavior of kidney

Version 2021 Non-Billable Code Neoplasm Unspecified Behavior

Not Valid for Submission

D49.51 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of neoplasm of unspecified behavior of kidney. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic calyx, renal ; Neoplasm, neoplastic kidney (parenchymal) ; Neoplasm, neoplastic kidney (parenchymal) calyx ; Neoplasm, neoplastic kidney (parenchymal) hilus ; Neoplasm, neoplastic kidney (parenchymal) pelvis ; Neoplasm, neoplastic parenchyma, kidney ; Neoplasm, neoplastic pelvis, pelvic renal ; etc

ICD-10:D49.51
Short Description:Neoplasm of unspecified behavior of kidney
Long Description:Neoplasm of unspecified behavior of kidney

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

  • D49.511 - Neoplasm of unspecified behavior of right kidney
  • D49.512 - Neoplasm of unspecified behavior of left kidney
  • D49.519 - Neoplasm of unspecified behavior of unspecified kidney

Code Classification

  • Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (D50–D89)
    • Neoplasms of unspecified behavior (D49)
      • Neoplasms of unspecified behavior (D49)

Code History

Table of Neoplasms

The code D49.51 is included 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.
