About coding Orf
The ICD-10-CM code for Orf is B08.02 (Orf virus disease).
Within B08.0 (other orthopoxvirus infections), B08.02 is specifically for Orf virus disease. Related codes cover Cowpox and vaccinia not from vaccine (B08.01), Pseudocowpox [milker's node] (B08.03), 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.
