About coding Tanapox
The ICD-10-CM code for Tanapox is B08.71 (Tanapox virus disease).
Within B08.7 (yatapoxvirus infections), B08.71 is specifically for Tanapox virus disease. Related codes cover yatapoxvirus infection, unspecified (B08.70), Yaba pox virus disease (B08.72) and other yatapoxvirus infections (B08.79).
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 865 (Viral Illness with MCC, relative weight 1.3485) and DRG 866 (Viral Illness without MCC, relative weight 0.8692), 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.
