Malignant neoplasm of small intestine, unspecified
ICD-10 C17.9 is a billable code used to indicate a diagnosis of malignant neoplasm of small intestine, unspecified.
C17.9 refers to a malignant neoplasm located in the small intestine, where the specific site of the tumor is not clearly defined. The small intestine comprises the duodenum, jejunum, and ileum, and malignancies can arise from any of these segments. Small intestine cancers are relatively rare, accounting for approximately 1-2% of all gastrointestinal cancers. The most common types include adenocarcinoma, carcinoid tumors, and lymphoma. Symptoms may include abdominal pain, weight loss, nausea, and changes in bowel habits, which can lead to diagnostic challenges. Imaging studies such as CT scans and endoscopy are often required for diagnosis, but due to the small size and location of the tumors, they can be easily overlooked. The unspecified nature of this code indicates that further specificity regarding the tumor's location or type is not available, which can complicate treatment planning and epidemiological tracking. Accurate coding is essential for appropriate management and research into this rare malignancy.
Detailed pathology reports, imaging studies, and treatment plans.
Diagnosis and management of small intestine tumors, staging of cancer, and treatment planning.
Ensure all relevant diagnostic tests are documented to support the malignancy diagnosis.
Endoscopy reports, biopsy results, and clinical notes detailing symptoms and findings.
Evaluation of gastrointestinal symptoms, performing endoscopic procedures, and obtaining biopsies.
Document the rationale for endoscopic procedures and any findings that may indicate malignancy.
Used when a patient with a diagnosed small intestine malignancy undergoes surgical resection.
Operative report detailing the procedure and findings.
Oncology and surgical documentation must align for accurate coding.
In such cases, C17.9 should be used, but ensure that all other clinical information is thoroughly documented to support the diagnosis.
