Y78.8 — Miscellaneous radiological devices associated with adverse incidents, not elsewhere classified
Is Y78.8 billable?
Yes, but Y78.8 is an unspecified code. Y78.8 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, Y78.8 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting Y78.8 — the more specific alternatives are listed below.

Excludes2 — not included here — inherited from Y70-Y82
The conditions below are not part of Y78.8, but a patient may have both at the same time. When documentation supports it, Y78.8 and the excluded code may both be reported.
- later complications following use of medical devices without breakdown or malfunctioning of device (Y83-Y84)
- misadventure to patients during surgical and medical care, classifiable to (Y62-Y69)
- surgical and other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure (Y83-Y84)
