About T85.735
T85.735 is the ICD-10-CM diagnosis code for infection and inflammatory reaction due to cranial or spinal infusion catheter. 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 3 subcodes must be used instead.
Within T85.73 (infection and inflammatory reaction due to nervous system devices, implants and graft), T85.735 is specifically for infection and inflammatory reaction due to cranial or spinal infusion catheter. Related codes cover ventricular intracranial (communicating) shunt (T85.730), implanted electronic neurostimulator of brain, electrode (lead) (T85.731), implanted electronic neurostimulator of peripheral nerve, electrode (lead) (T85.732), implanted electronic neurostimulator of spinal cord, electrode (lead) (T85.733), implanted electronic neurostimulator, generator (T85.734) and other nervous system device, implant or graft (T85.738).
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 was added in FY2017, effective October 1, 2016.
7th character
The appropriate 7th character is to be added to each code from category T85
