About coding injection procedure complication
The ICD-10-CM code for injection procedure complication is T80.90 (Unspecified complication following infusion and therapeutic injection). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on T80.90.
Within T80.9, choose T80.90 (Unspecified complication following infusion and therapeutic injection) only when documentation doesn't support a more specific option: hemolytic transfusion reaction, unspecified incompatibility (T80.91) and unspecified transfusion reaction (T80.92).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
