ICD-10 code for pulmonary distomiasis

The ICD-10-CM code for pulmonary distomiasis is B66.4 (Paragonimiasis).

Within B66 (other fluke infections), B66.4 is specifically for Paragonimiasis. Related codes cover Opisthorchiasis (B66.0), Clonorchiasis (B66.1), Dicroceliasis (B66.2), Fascioliasis (B66.3), Fasciolopsiasis (B66.5), other specified fluke infections (B66.8) and fluke infection, unspecified (B66.9).

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 177 (Respiratory Infections and Inflammations with MCC, relative weight 1.6092), DRG 178 (Respiratory Infections and Inflammations with CC, relative weight 0.9744) and DRG 179 (Respiratory Infections and Inflammations without CC/MCC, relative weight 0.7345), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
