2024 ICD-10-CM Diagnosis Code D49.512
Neoplasm of unspecified behavior of left kidney
- ICD-10-CM Code:
- D49.512
- ICD-10 Code for:
- Neoplasm of unspecified behavior of left kidney
- Is Billable?
- Yes - Valid for Submission
- Chronic Condition Indicator: [1]
- Not chronic
- Code Navigator:
D49.512 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of unspecified behavior of left kidney. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
The following anatomical sites found in the Table of Neoplasms reference the parent code D49.51 of the current diagnosis 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
Unspecified diagnosis codes like D49.512 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.
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Bilateral neoplasm of kidneys
- Neoplasm of left kidney
Clinical Classification
Clinical Category is Neoplasms of unspecified nature or uncertain behavior
- CCSR Category Code: NEO072
- Inpatient Default CCSR: Y - Yes, default inpatient assignment for principal diagnosis or first-listed diagnosis.
- Outpatient Default CCSR: Y - Yes, default outpatient assignment for principal diagnosis or first-listed diagnosis.
Replacement Code
D49512 replaces the following previously assigned ICD-10-CM code(s):
- D49.5 - Neoplasm of unsp behavior of other genitourinary organs
Convert D49.512 to ICD-9-CM
- ICD-9-CM Code: 239.5 - Other gu neoplasm NOS
Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.
Table of Neoplasms
The parent code D49.51 of the current diagnosis 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.

Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
