C64 refers to Malignant neoplasm of kidney, except renal pelvis, a group of cancers that affect the urinary system, including the kidney, ureter, bladder, and associated structures. These cancers often require imaging and biopsy for diagnosis and may present with urinary symptoms or systemic signs. ICD10 coding ensures accurate medical records, reimbursement, and cancer registry entry.

Symptoms

Hematuria – Blood in the urine is a hallmark sign
Flank or abdominal pain – Especially in kidney or ureteral tumors
Frequent urination – Common with bladder tumors
Burning sensation – During urination or persistent discomfort
Pelvic pain – Indicative of advanced or spreading disease
Fatigue and weight loss – Seen in late-stage cancers
Urinary retention – Can result from tumor obstruction

Diagnosis

Diagnosis of Malignant neoplasm of kidney, except renal pelvis involves urinalysis, imaging studies (ultrasound, CT urogram, MRI), cystoscopy, and biopsy. In some cases, cytology or tumor marker tests are used. Early detection through hematuria workups can improve prognosis, especially for bladder and kidney cancers.

ICD10 Code Usage

ICD10 code C64 is used by urologists, oncologists, and coders to accurately classify urinary tract cancers in clinical documentation and billing. It supports insurance claims, national cancer databases, and patient outcome tracking for genitourinary cancers.
