Is Y84 billable?

No — Y84 is a non-billable header code. Y84 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 10 billable codes beneath Y84.

Excludes1 — never code together — inherited from Y83-Y84

The conditions below can never be reported together with Y84 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • misadventures to patients during surgical and medical care, classifiable to (Y62-Y69)

Excludes2 — not included here — inherited from Y83-Y84

The conditions below are not part of Y84, but a patient may have both at the same time. When documentation supports it, Y84 and the excluded code may both be reported.

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