About coding Tahyna fever

The ICD-10-CM code for Tahyna fever is B33.8 (Other specified viral diseases).

Within B33, choose B33.8 (Other specified viral diseases) only when documentation doesn't support a more specific option: epidemic myalgia (B33.0), Ross River disease (B33.1), viral carditis (B33.2), retrovirus infections, not elsewhere classified (B33.3) and Hantavirus (cardio)-pulmonary syndrome [HPS] [HCPS] (B33.4).

Don't report B33.8 together with the conditions in its Excludes1 note: anogenital human papillomavirus infection (A63.0) and viral warts due to human papillomavirus infection (B07).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

Don't confuse with (Excludes1 for B33.8)

  • anogenital human papillomavirus infection (A63.0)
  • viral warts due to human papillomavirus infection (B07)
