    ICD-10-CM Code For Other Cestode Infections: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B71 includes infections caused by cestode parasites such as tapeworms, covering intestinal infections and extraintestinal cystic disease. These ICD-10-CM diagnosis codes are used to document clinical scenarios including symptomatic intestinal infestation, complications like obstruction, or tissue cysts affecting organs. Accurate coding within the ICD-10-CM B71 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM B71: Other Cestode Infections Overview

    The ICD-10-CM B71 group includes infections caused by tapeworms and related cestode species that can affect the gastrointestinal tract and, in some cases, extraintestinal sites. These diagnoses target parasitic helminthic disease processes and potential organ involvement such as intestinal obstruction or cystic lesions. Accurate coding matters for capturing disease complexity and supporting appropriate clinical documentation and reimbursement.

    When to Use

    Use a code from this group when a confirmed or clinically diagnosed cestode infection is documented, including symptomatic intestinal infestation or identified cysts in tissues. Codes from this group are appropriate when clinical records describe complications or organ involvement attributable to the cestode infection.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden onset severe abdominal pain, high fever, and signs of peritonitis after recent travel to an endemic area; imaging and stool examination identify intestinal obstruction and heavy infestation with tapeworm segments consistent with a non-Taenia cestode species causing acute intestinal helminthiasis. A diagnosis from this group is assigned to capture the acute symptomatic cestode infection requiring urgent medical and sometimes surgical management. Typical codes: B71.0, B71.9
    • A middle-aged patient in outpatient infectious disease clinic reports months of intermittent abdominal discomfort, chronic diarrhea, weight loss, and eosinophilia after consuming raw freshwater fish during travel; stool O&P and serology confirm a chronic extraintestinal or prolonged intestinal infection with a less common cestode species. This scenario represents a chronic/ongoing parasitic infection where a code from this group is used to document the persistent cestode infection and guide longitudinal care and public health reporting. Typical codes: B71.1, B71.9
    • An inpatient with immunosuppression (e.g., transplant recipient) develops neurological symptoms and imaging shows cystic lesions consistent with disseminated cestode involvement beyond the gut; biopsy/serology supports a complication of a non-Tenia cestode infection causing systemic disease. Here a diagnosis from this group is used to indicate complicated or extraintestinal manifestations of a cestode infection as a comorbidity contributing to the patient’s clinical course. Typical codes: B71.8, B71.9
