Malignant neoplasm of appendix
ICD-10 C18.1 is a billable code used to indicate a diagnosis of malignant neoplasm of appendix.
Malignant neoplasm of the appendix, classified under ICD-10 code C18.1, refers to cancerous growths that originate in the appendix. This condition is relatively rare compared to other colorectal cancers, but it can present significant clinical challenges. The appendix is a small, tube-like structure attached to the large intestine, and when malignant, it can lead to various symptoms including abdominal pain, changes in bowel habits, and gastrointestinal obstruction. Diagnosis typically involves imaging studies such as CT scans or MRIs, and definitive diagnosis is made through histopathological examination of biopsy samples. Staging of the disease is crucial for determining treatment options and prognosis, often utilizing the AJCC (American Joint Committee on Cancer) staging system. Microsatellite instability (MSI) testing may be performed to assess the tumor's genetic characteristics, which can influence treatment decisions. Surgical resection remains the primary treatment modality, often involving appendectomy or more extensive procedures depending on the extent of the disease. Adjuvant therapies may also be considered based on staging and individual patient factors.

Operative report detailing the procedure and findings.
Ensure that the surgical approach and any findings are clearly documented.
Common symptoms include abdominal pain, changes in bowel habits, gastrointestinal obstruction, and unexplained weight loss.
Diagnosis typically involves imaging studies such as CT scans, followed by biopsy for histopathological examination.
Microsatellite instability can indicate a specific genetic profile that may influence treatment options, including the potential use of immunotherapy.
