What This Code Means
B67.90 is the ICD-10-CM diagnosis code for echinococcosis, unspecified. Echinococcosis is a parasitic infection caused by tapeworm larvae that form cysts in the body, most commonly in the liver, lungs, or brain. This code is used when the specific type or location of the echinococcosis infection cannot be determined. B67.90 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering helminthiases (b65-b83).
B67.90 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.
Use this unspecified code only when documentation does not indicate the specific site (liver, lung, bone, etc.) or type (cystic vs. alveolar) of echinococcosis; query the provider if more specific information is available.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for B67.90 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this unspecified code only when documentation does not indicate the specific site (liver, lung, bone, etc.) or type (cystic vs. alveolar) of echinococcosis; query the provider if more specific information is available
- •This is typically associated with exposure to infected animals (dogs, sheep) or contaminated food/water; consider documenting the geographic origin or exposure history for epidemiological tracking
