What This Code Means
B74.8 is the ICD-10-CM diagnosis code for other filariases. A parasitic infection caused by filarial worms other than the common types, affecting the lymphatic system or subcutaneous tissues. B74.8 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering helminthiases (b65-b83).
B74.8 is a billable ICD-10-CM code, but the current payload does not show a mapping under the CMS-HCC V28 or V24 community payment models, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Use this code only when the specific type of filaria is documented but not Wuchereria bancrofti or Brugia malayi.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for B74.8 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code only when the specific type of filaria is documented but not Wuchereria bancrofti or Brugia malayi
- •Review documentation for the specific organism identified to ensure B74.8 is the most appropriate code
