About coding cutaneous strongyloidiasis
The ICD-10-CM code for cutaneous strongyloidiasis is B78.1 (Cutaneous strongyloidiasis).
Within B78 (strongyloidiasis), B78.1 is specifically for cutaneous strongyloidiasis. Related codes cover intestinal strongyloidiasis (B78.0), disseminated strongyloidiasis (B78.7) and unspecified (B78.9).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 602 (Cellulitis with MCC, relative weight 1.4273) and DRG 603 (Cellulitis without MCC, relative weight 0.8635), in MDC 09 (Diseases and Disorders of the Skin, Subcutaneous Tissue and Breast), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
