Code Description

ICD-10 C67.7 is a billable code used to indicate a diagnosis of malignant neoplasm of urachus.

Key Diagnostic Point:

Malignant neoplasm of the urachus is a rare type of cancer that arises from the urachus, a remnant of the embryonic allantois that connects the bladder to the umbilicus. This neoplasm is classified under urinary tract malignancies and is often associated with other bladder cancers. The urachus is located in the anterior abdominal wall, and tumors can present as either adenocarcinomas or other histological types. Symptoms may include hematuria, abdominal pain, and urinary obstruction. Diagnosis typically involves imaging studies such as ultrasound, CT scans, or MRI, followed by biopsy for histological confirmation. Staging of urachal cancer is crucial for determining treatment options and prognosis, often following the AJCC (American Joint Committee on Cancer) staging system. Surgical management is the primary treatment modality, which may include partial or total cystectomy, depending on the extent of the disease. Adjuvant therapies such as chemotherapy or radiation may be considered based on the tumor's characteristics and staging.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Rarity of the condition leading to limited coding resources
  • Need for precise staging information
  • Variability in histological types requiring specific documentation
  • Potential for misclassification with other urinary tract malignancies

Audit Risk Factors

  • Inadequate documentation of staging
  • Misclassification of tumor type
  • Failure to document surgical procedures performed
  • Inconsistent coding of associated conditions

Specialty Focus

Medical Specialties

Urology

Documentation Requirements

Detailed surgical notes, pathology reports, imaging studies, and staging information.

Common Clinical Scenarios

Diagnosis and management of urachal tumors, surgical interventions, and follow-up care.

Billing Considerations

Urologists must ensure comprehensive documentation of tumor characteristics and staging to support accurate coding.
