Renal Mass ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Renal Mass?

Here are the numerous Renal Mass ICD codes you can use when coding or billing, depending on the mass the test may reveal.

• C64: Malignant neoplasm of kidney, except renal pelvis
• C64.1: Malignant neoplasm of right kidney, except renal pelvis
• C64.2: Malignant neoplasm of left kidney, except renal pelvis
• C64.9: Malignant neoplasm of unspecified kidney, except renal pelvis
• C65: Malignant neoplasm of renal pelvis
• C65.1: Malignant neoplasm of right renal pelvis
• C65.2: Malignant neoplasm of left renal pelvis
• C65.9: Malignant neoplasm of unspecified renal pelvis

Neoplasm

• D41.0: Neoplasm of uncertain behavior or unspecified kidney
• D41.00: Neoplasm of uncertain behavior or unspecified kidney
• D41.01: Neoplasm of undertain behavior of right kidney
• D41.02: Neoplasm of uncertain behavior or left kidney
• D41.1: Neoplasm of uncertain behavior of renal pelvis
• D41.10: Neoplasm of uncertain behavior of unspecified renal pelvis
• D41.11: Neoplasm of uncertain behavior of right renal pelvis
• D41.12: Neoplasm of uncertain behavior of left renal pelvis
• D49.51: Neoplasm of unspecified behavior of kidney
• 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

Benign Neoplasm

• D30.0: Benign neoplasm of kidney
• D30.00: Benign neoplasm of unspecified kidney
• D30.01: Benign neoplasm of right kidney
• D30.02: Benight neoplasm of left kidney
• D30.1: Benign neoplasm of renal pelvis
• D30.10: Benign neoplasm of unspecified renal pelvis
• D30.11: Benign neoplasm of right renal pelvis
• D30.12: Benign neoplasm of left renal pelvis

Which Renal Mass ICD codes are Billable?

The more specific codes under C64, C65, D41.0, D41.1, D49.51, D30.0, D31.1 are billable. However, the aforementioned codes aren’t billable due to the lack of specificity. 

Clinical Information

• A renal mass is an abnormal growth in the renal cortex or the kidney that can be cancerous (malignant) or not cancerous (benign). 
• There are multiple types of renal tumors, but the main ones are renal cell carcinomas, benign renal tumors, and Wilms tumors. What differentiates them from one another are location, size, and the age of the patient. 
• Patients don’t usually exhibit symptoms until the mid to late stages, so these tumors are usually found by chance during the early stages. However, if a patient has any symptoms, they would be the following: blood in urine, loss of appetite, unexplained weight loss, anemia, low back pain on one side, and fever not caused by an infection for an extended period. 
• People at risk of developing tumors in the kidney are those who smoke, are obese, drink a lot of alcohol, have a family history of high blood pressure/kidney cancer, are constantly exposed to chemicals, and are undergoing kidney dialysis. 
• To diagnose a renam mass, a practitioner will ask for a patient’s medical history, conduct a physical exam and have them undergo other tests like CMP, CBC, urinalysis, kidney function tests, and imaging tests. 
• Treatment will vary depending on the size, stage, and profession. Some usual treatments are active surveillance, nephrectomy, and ablation.

Synonyms Include:

• Nephroblastoma
• Metastatic renal cell carcinoma 
• Sarcoma of kidney
• Bilateral neoplasm of kidneys
• Mesoblastic nephroma
