Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Infection due to intestinal helminths classified to more than one of the categories B65.0-B81.3 and B81.8
  • Mixed helminthiasis NOS

Risk adjustment

B81.4 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to B81.4.
