Code Description

ICD-10 C17.2 is a billable code used to indicate a diagnosis of malignant neoplasm of ileum.

Key Diagnostic Point:

Malignant neoplasm of the ileum refers to cancerous tumors that arise in the ileum, the final section of the small intestine. This type of cancer is relatively rare compared to other gastrointestinal malignancies, such as colorectal cancer. The ileum is responsible for nutrient absorption, and tumors in this area can lead to significant complications, including obstruction, perforation, and malabsorption. Symptoms may include abdominal pain, weight loss, changes in bowel habits, and gastrointestinal bleeding. Diagnosis often involves imaging studies such as CT scans or MRIs, endoscopy, and biopsy to confirm malignancy. Due to the rarity of ileal tumors, they can be challenging to diagnose, often being mistaken for other gastrointestinal disorders. Treatment typically involves surgical resection of the tumor, and depending on the stage, may also include chemotherapy or radiation therapy. The prognosis varies based on the tumor's size, location, and metastasis at the time of diagnosis.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Rarity of the condition leading to potential misdiagnosis.
  • Need for precise documentation of tumor location and characteristics.
  • Variability in treatment protocols based on staging.
  • Potential for multiple coding scenarios depending on metastasis.

Audit Risk Factors

  • Inadequate documentation of tumor size and staging.
  • Failure to specify the exact location of the neoplasm.
  • Misclassification of the tumor type (malignant vs. benign).
  • Inconsistent coding of associated procedures or treatments.

Specialty Focus

Medical Specialties

Oncology

Documentation Requirements

Detailed pathology reports, imaging studies, and treatment plans.

Common Clinical Scenarios

Diagnosis and management of ileal tumors, staging, and treatment planning.

Billing Considerations

Ensure accurate coding of chemotherapy and radiation therapy as adjunct treatments.

Gastroenterology

Documentation Requirements

Endoscopy reports, biopsy results, and imaging findings.

Common Clinical Scenarios

Evaluation of gastrointestinal symptoms leading to the diagnosis of ileal malignancy.

Billing Considerations

Documentation must clearly differentiate between benign and malignant findings.

  • According to ICD
  • 10 coding guidelines, C17
  • 2 should be used when the diagnosis of malignant neoplasm of the ileum is confirmed through pathology
  • Coders must ensure that the documentation supports the diagnosis and includes details about the tumor's size, location, and any metastasis

Exclusion Criteria

Do NOT use C17.2 When
  • Exclusion criteria include benign neoplasms and other gastrointestinal cancers

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of malignant neoplasms, including those of the ileum. This specificity aids in better tracking of disease prevalence and treatment outcomes, although it requires coders to be more knowledgeable about the nuances of gastrointestinal cancers.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of malignant neoplasms, including those of the ileum. This specificity aids in better tracking of disease prevalence and treatment outcomes, although it requires coders to be more knowledgeable about the nuances of gastrointestinal cancers.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of malignant neoplasms, including those of the ileum.
