About coding bilharziasis oriental
The ICD-10-CM code for bilharziasis oriental is B65.2 (Schistosomiasis due to Schistosoma japonicum).
Within B65 (schistosomiasis [bilharziasis]), B65.2 is specifically for schistosomiasis due to Schistosoma japonicum. Related codes cover schistosomiasis due to Schistosoma haematobium [urinary schistosomiasis] (B65.0), schistosomiasis due to Schistosoma mansoni [intestinal schistosomiasis] (B65.1), Cercarial dermatitis (B65.3), other schistosomiasis (B65.8) and schistosomiasis, unspecified (B65.9).
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 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.
