What 36455 covers
This service involves removing a patient’s blood while replacing it with donor blood as part of an exchange transfusion. It is distinct from a routine transfusion, which administers blood or blood components without exchanging the patient’s blood. Hematology, critical care, or other clinicians may perform the procedure in a hospital or another setting equipped to manage transfusion procedures. A common clinical context is exchange transfusion for a patient with sickle cell disease.
Report 36455 for an exchange transfusion in a patient who is not a newborn; use the newborn-specific codes when the patient and procedure meet those code descriptions. Documentation should identify the indication, the exchange performed, and the patient’s status as non-newborn. The code represents the exchange service, not a separate service for each portion of blood removed or infused. When other procedures are performed in the same session, CMS pays the highest-valued procedure in full and reduces the other procedures to 50% under the standard multiple procedure rule.

36455 billing questions
How is 36455 distinguished from 36450?
36455 is for exchange transfusion in a patient other than a newborn. Code 36450 is the newborn exchange transfusion code.

Is a routine blood transfusion reported with 36455?

Under the standard multiple procedure reduction, CMS pays the highest-valued procedure in full and reduces the other procedures to 50%.
What documentation supports reporting 36455?
