ICD-10 Code B71.8 – Other specified cestode infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B71.8 – Other specified cestode infections
What it is
B71.8 identifies cestode, or tapeworm, infections that do not fit a more specific ICD-10 category. Use it when documentation names an uncommon or otherwise specified tapeworm infection.
Clinical signs
Clinical features vary; refer to documentation. Patients may have gastrointestinal complaints, weight loss, or passage of tapeworm segments, but the exact presentation depends on the species involved.
When to use this code
Use B71.8 when the provider documents a cestode infection that is specified but not listed elsewhere in ICD-10. It is appropriate when the record identifies a tapeworm infection and no more specific code applies. Check documentation if the organism is unclear.
Do not use for
Do not use this code for infections with a more specific cestode code, or when the chart only says “tapeworm” without further detail. Check documentation if the diagnosis is uncertain.
Coding tip
Code the most specific cestode diagnosis documented, and query the provider when the species or infection type is not clearly identified.
