Code Description

ICD-10 C17.1 is a billable code used to indicate a diagnosis of malignant neoplasm of jejunum.

Key Diagnostic Point:

Malignant neoplasm of the jejunum is a rare form of cancer that arises from the epithelial cells lining the jejunum, which is the middle section of the small intestine. This type of cancer can manifest as adenocarcinomas, lymphomas, or neuroendocrine tumors, with adenocarcinomas being the most common. Symptoms may include abdominal pain, weight loss, nausea, vomiting, and gastrointestinal bleeding. Due to the nonspecific nature of these symptoms, diagnosis can be challenging and often requires imaging studies such as CT scans, MRI, or endoscopy with biopsy for definitive diagnosis. The rarity of jejunal malignancies, accounting for only 1-2% of all gastrointestinal cancers, complicates early detection and treatment. Treatment typically involves surgical resection, chemotherapy, and sometimes radiation therapy, depending on the stage and type of cancer. The prognosis varies significantly based on the tumor type, stage at diagnosis, and response to treatment.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Rarity of the condition leading to potential misdiagnosis
  • Variability in tumor types and presentations
  • Need for comprehensive documentation of diagnostic imaging and pathology results
  • Potential for overlapping symptoms with other gastrointestinal disorders

Audit Risk Factors

  • Inadequate documentation of diagnostic imaging
  • Failure to specify tumor type (e.g., adenocarcinoma vs. lymphoma)
  • Lack of clarity in treatment plans and outcomes
  • Misclassification of the site of the tumor

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of small intestine malignancies, improving the accuracy of data collection and reimbursement processes. C17.1 provides a distinct code for jejunal malignancies, which were previously grouped under broader categories in ICD-9.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of small intestine malignancies, improving the accuracy of data collection and reimbursement processes. C17.1 provides a distinct code for jejunal malignancies, which were previously grouped under broader categories in ICD-9.

Reimbursement & Billing Impact
