Malignant neoplasm of anus and anal canal
Chapter 2:Neoplasms
ICD-10 C21 is a billable code used to indicate a diagnosis of malignant neoplasm of anus and anal canal.
Malignant neoplasm of the anus and anal canal refers to cancerous growths that originate in the anal region, which includes the anus and the anal canal. This type of cancer is relatively rare compared to other colorectal cancers but has been increasing in incidence, particularly among certain populations. The primary risk factors include human papillomavirus (HPV) infection, immunosuppression, and a history of anal warts. Symptoms may include rectal bleeding, anal pain, and changes in bowel habits. Diagnosis typically involves a combination of physical examination, imaging studies, and biopsy. Staging of anal cancer is crucial for determining treatment options and prognosis, with the American Joint Committee on Cancer (AJCC) staging system commonly used. Treatment may involve surgery, radiation therapy, and chemotherapy, depending on the stage and location of the tumor. Microsatellite instability (MSI) testing may also be relevant in some cases, as it can influence treatment decisions, particularly in the context of immunotherapy. Early detection through screening is vital, especially for high-risk populations, to improve outcomes.
Detailed pathology reports, imaging studies, and treatment plans.
Diagnosis and management of anal cancer, including staging and treatment planning.
Ensure accurate documentation of tumor characteristics and treatment response.
Endoscopy reports, biopsy results, and follow-up care documentation.
Screening for anal cancer in high-risk populations and management of anal dysplasia.
Document any findings from colonoscopy or other diagnostic procedures.
Used when a biopsy is performed to confirm anal cancer diagnosis.
Document the indication for the biopsy and findings.
Ensure that the procedure is linked to the diagnosis of anal cancer.
Common symptoms include rectal bleeding, anal pain, a lump near the anus, and changes in bowel habits. If you experience any of these symptoms, it is important to consult a healthcare provider for evaluation.
