What This Code Means
B71.1 is the ICD-10-CM diagnosis code for dipylidiasis. An intestinal tapeworm infection acquired by eating raw or undercooked meat containing the parasite, also known as the double-pored tapeworm. B71.1 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering helminthiases (b65-b83).
B71.1 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Document dietary history, particularly consumption of undercooked pork, beef, or poultry.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B71.1 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document dietary history, particularly consumption of undercooked pork, beef, or poultry
- •Dipylidiasis is more common in pets and can be transmitted to humans; note if there is pet exposure
