2022 ICD-10-CM Code D49.51

Neoplasm of unspecified behavior of kidney

Version 2021

Not Valid for Submission

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

D49.51 is a non-specific and non-billable diagnosis 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 specific and is NOT valid for the year 2022 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 apply to this code given the correct histological behavior: calyx, renal ; kidney (parenchymal) ; kidney (parenchymal) calyx ; kidney (parenchymal) hilus ; kidney (parenchymal) pelvis ; parenchyma, kidney ; pelvis, pelvic renal ; etc

Unspecified diagnosis codes like D49.51 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 for Neoplasm of unspecified behavior of kidney

Non-specific codes like D49.51 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for neoplasm of unspecified behavior of kidney:

  • BILLABLE CODE - Use D49.511 for Neoplasm of unspecified behavior of right kidney
  • BILLABLE CODE - Use D49.512 for Neoplasm of unspecified behavior of left kidney
  • BILLABLE CODE - Use D49.519 for Neoplasm of unspecified behavior of unspecified kidney

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.
