About T85.86
T85.86 is the ICD-10-CM diagnosis code for thrombosis due to internal prosthetic devices, implants and grafts, not elsewhere classified. It belongs to category T85 (complications of other internal prosthetic devices, implants and grafts), block T80-T88 (complications of surgical and medical care, not elsewhere classified) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 5 subcodes must be used instead.
Within T85.8 (other specified complications of internal prosthetic devices, implants and grafts, not elsewhere classified), T85.86 is specifically for thrombosis due to internal prosthetic devices, implants and grafts, not elsewhere classified. Related codes cover embolism due to internal prosthetic devices, implants and grafts, not elsewhere classified (T85.81), fibrosis due to internal prosthetic devices, implants and grafts, not elsewhere classified (T85.82), hemorrhage due to internal prosthetic devices, implants and grafts, not elsewhere classified (T85.83), pain due to internal prosthetic devices, implants and grafts, not elsewhere classified (T85.84), stenosis due to internal prosthetic devices, implants and grafts, not elsewhere classified (T85.85) and other specified complication of internal prosthetic devices, implants and grafts, not elsewhere classified (T85.89).
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.
