About coding arthritis sporotrichosis
The ICD-10-CM code for arthritis sporotrichosis is B42.82 (Sporotrichosis arthritis).
Within B42.8 (other forms of sporotrichosis), B42.82 is specifically for sporotrichosis arthritis. Related codes cover cerebral sporotrichosis (B42.81) and other forms of sporotrichosis (B42.89).
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 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.
