Code Description

ICD-10 C67.0 is a billable code used to indicate a diagnosis of malignant neoplasm of trigone of bladder.

Key Diagnostic Point:

C67.0 refers to a malignant neoplasm located specifically at the trigone of the bladder, which is the triangular area at the base of the bladder where the ureters enter and the urethra exits. This type of cancer is part of a broader category of urinary tract malignancies, which can include cancers of the bladder, ureters, and kidneys. The trigone is a critical area due to its role in urinary function and its proximity to other vital structures. Symptoms may include hematuria (blood in urine), dysuria (painful urination), and increased urinary frequency. Diagnosis typically involves imaging studies such as CT scans, cystoscopy, and biopsy to confirm malignancy. Staging of bladder cancer is crucial for determining the appropriate treatment plan and involves assessing the depth of invasion into the bladder wall and the presence of metastasis. Surgical management may include transurethral resection of the bladder tumor (TURBT) for superficial tumors or radical cystectomy for invasive cancers, often accompanied by urinary diversion procedures. The prognosis and treatment options depend significantly on the stage at diagnosis.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of bladder cancers, improving the accuracy of data collection and reimbursement processes. C67.0 provides a clear distinction for malignancies located at the trigone, which was less specific in ICD-9.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of bladder cancers, improving the accuracy of data collection and reimbursement processes. C67.0 provides a clear distinction for malignancies located at the trigone, which was less specific in ICD-9.

Reimbursement & Billing Impact

Frequently Asked Questions

What are the common symptoms of a malignant neoplasm of the trigone of the bladder?

Common symptoms include hematuria, dysuria, and increased urinary frequency. Patients may also experience pelvic pain or urinary retention.

How is staging determined for bladder cancer?

Staging is determined using the TNM system, which assesses tumor size, lymph node involvement, and the presence of metastasis.
