About coding thrombosis with thrombocytopenia syndrome
The ICD-10-CM code for thrombosis with thrombocytopenia syndrome is D75.84 (Other platelet-activating anti-PF4 disorders).
Within D75.8, choose D75.84 (Other platelet-activating anti-PF4 disorders) only when documentation doesn't support a more specific option: myelofibrosis (D75.81), Heparin induced thrombocytopenia (HIT) (D75.82), thrombocytosis (D75.83) and other specified diseases of blood and blood-forming organs (D75.89).
Use an additional code, if applicable, for adverse effect of other viral vaccine (T50.B95-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
