Y78 is a non-billable ICD-10-CM category code for radiological devices associated with adverse incidents, so it cannot be submitted on claims. Use a more specific code from this category instead, such as Y78.0, Y78.1, Y78.2, and Y78.3.

Specific Coding for Radiological devices associated with adverse incidentsOverview

Non-specific codes like Y78 require more characters. Use one of these billable codes instead:

  • Use Y78.0 for Diagnostic and monitoring radiological devices associated with adverse incidents

  • Use Y78.1 for Therapeutic (nonsurgical) and rehabilitative radiological devices associated with adverse incidents

  • Use Y78.2 for Prosthetic and other implants, materials and accessory radiological devices associated with adverse incidents

  • Use Y78.3 for Surgical instruments, materials and radiological devices (including sutures) associated with adverse incidents

  • Use Y78.8 for Miscellaneous radiological devices associated with adverse incidents, not elsewhere classified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to Y78: its own notes plus those printed at block Y70-Y82, block Y62-Y84, and Chapter 20. A note printed at a category, block or chapter applies to every code under it.

From Block Y70-Y82 Medical devices associated with adverse incidents in diagnostic and therapeutic use applies to 63 codes
  • breakdown or malfunction of medical devices (during use) (after implantation) (ongoing use)
From Block Y62-Y84 Complications of medical and surgical care applies to 115 codes
  • complications of medical devices
  • surgical and 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

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Block Y70-Y82 Medical devices associated with adverse incidents in diagnostic and therapeutic use applies to 63 codes
  • 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)

Notes

General instructions on how these codes are used.

From Chapter 20 (V00-Y99) External causes of morbidity and mortality applies to 7,461 codes
  • This chapter permits the classification of environmental events and circumstances as the cause of injury, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the Classification indicating the nature of the condition. Most often, the condition will be classifiable to Chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88). Other conditions that may be stated to be due to external causes are classified in Chapters I to XVIII. For these conditions, codes from Chapter 20 should be used to provide additional information as to the cause of the condition.
