About coding Pseudocowpox
The ICD-10-CM code for Pseudocowpox is B08.03 (Pseudocowpox [milker's node]).
Within B08.0 (other orthopoxvirus infections), B08.03 is specifically for Pseudocowpox [milker's node]. Related codes cover Cowpox and vaccinia not from vaccine (B08.01), Orf virus disease (B08.02), Paravaccinia, unspecified (B08.04) and other orthopoxvirus infections (B08.09).
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 606 (Minor Skin Disorders with MCC, relative weight 1.5728) and DRG 607 (Minor Skin Disorders without MCC, relative weight 0.8772), 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.
