Excludes1 — never code together — inherited from Y62-Y69

The conditions below can never be reported together with Y64 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

surgical and medical procedures as the cause of abnormal reaction of the patient, without mention of misadventure at the time of the procedure (Y83-Y84)

Excludes2 — not included here — inherited from Y62-Y69

The conditions below are not part of Y64, but a patient may have both at the same time. When documentation supports it, Y64 and the excluded code may both be reported.

breakdown or malfunctioning of medical device (during procedure) (after implantation) (ongoing use) (Y70-Y82)
