ICD-10 code for multilocularis echinococcus

The ICD-10-CM code for multilocularis echinococcus is B67.7 (Echinococcus multilocularis infection, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on B67.7.

Within B67, choose B67.7 (Echinococcus multilocularis infection, unspecified) only when documentation doesn't support a more specific option: Echinococcus granulosus infection of liver (B67.0), Echinococcus granulosus infection of lung (B67.1), Echinococcus granulosus infection of bone (B67.2), Echinococcus granulosus infection, other and multiple sites (B67.3), Echinococcus granulosus infection, unspecified (B67.4), Echinococcus multilocularis infection of liver (B67.5), Echinococcus multilocularis infection, other and multiple sites (B67.6), unspecified, of liver (B67.8) and 1 more.

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235) and DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
