    ICD-10-CM Code For Diphyllobothriasis And Sparganosis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B70 includes infections due to diphyllobothriid tapeworms and sparganum larval infections, covering intestinal cestode infection and larval migration into tissues. These ICD-10-CM diagnosis codes are used to document clinical encounters for parasitic cestode infections, capturing site of infection, presence of complications, and disease specificity relevant to this group. Accurate coding within the ICD-10-CM B70 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM B70: Diphyllobothriasis And Sparganosis Overview

    The ICD-10-CM B70 group captures infections caused by specific tapeworms and their larval forms affecting humans. These conditions primarily involve the gastrointestinal tract and occasionally soft tissues where larvae migrate. Accurate coding is important for complete clinical documentation and can affect reimbursement by clearly conveying the diagnosis.

    When to Use

    Use a code from this group when a patient has a confirmed or clinically diagnosed infection due to diphyllobothriid tapeworms or sparganum larvae. Select the code that best reflects the organism, site of infection, and any documented complications when reporting the encounter.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with acute onset abdominal pain, profuse watery diarrhea, and visible segments of a tapeworm in a stool sample after recent consumption of undercooked freshwater fish. Stool ova and parasite testing confirms Diphyllobothrium infection, prompting assignment of the specific diphyllobothriasis code for active infection. Typical codes: B70.0
    • A middle-aged patient with chronic fatigue and progressive macrocytic anemia is evaluated in outpatient hematology after years of nonspecific gastrointestinal complaints and a history of frequent raw fish consumption while traveling; serology and stool studies identify a longstanding tapeworm infestation causing vitamin B12 deficiency. Because the presentation reflects a chronic helminth infection with systemic sequelae, the chronic diphyllobothriasis code is used. Typical codes: B70.0
    • An older adult is admitted for management of an ocular mass and migratory subcutaneous nodules after exposure to contaminated water and consumption of raw amphibian meat; biopsy reveals sparganum larvae consistent with sparganosis, requiring diagnosis coding for this parasitic tissue infection. Typical codes: B70.1
