W86 is a non-billable ICD-10-CM category code for exposure to other specified electric current, so it cannot be submitted on claims. Use a more specific code from this category instead, such as W86.0XXA, W86.0XXD, W86.0XXS, and W86.1XXA.

Specific Coding for Exposure to other specified electric currentOverview

Non-specific codes like W86 require more characters. Use one of these billable codes instead:

  • W86.0 for Exposure to domestic wiring and appliances

  • W86.1 for Exposure to industrial wiring, appliances and electrical machinery

  • W86.8 for Exposure to other electric current

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to W86: its own notes plus those printed at block W85-W99 and Chapter 20. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block W85-W99 Exposure to electric current, radiation and extreme ambient air temperature and pressure applies to 99 codes
  • exposure to:
  • failure in dosage of radiation or temperature during surgical and medical care (Y63.2-Y63.5)
  • lightning (T75.0-)
  • natural cold (X31)
  • natural heat (X30)
  • natural radiation NOS (X39)
  • radiological procedure and radiotherapy (Y84.2)
  • sunlight (X32)

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.

7th Character

Every code in the category takes a 7th character from the listed values, with the placeholder X filling any empty positions before it.

  • The appropriate 7th character is to be added to each code from category W86
Values for category W86 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

  • W28 Contact with powered lawn mower
    exposure to electric current (W86.-)

Patient EducationClinical

Electrical Injuries

When you come in direct contact with electricity, it can pass through your body and cause injuries. These electrical injuries can be external or internal. You may have one or both types. External injuries are skin burns. Internal injuries include damage to your organs, bones, muscles, and nerves.

Questions About W86Overview

What is the ICD-10 code for exposure to other specified electric current?

W86 is the ICD-10-CM category for exposure to other specified electric current, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is W86 (Exposure to other specified electric current) a billable code?

No. This is a category header that groups the codes for exposure to other specified electric current, and headers cannot be submitted on claims. Claims for exposure to other specified electric current need a more specific code from this category, such as W86.0XXA, W86.0XXD, and W86.0XXS.

Can W86 be reported with a code from T75.0?

Not as a rule. The Excludes1 note at block W85-W99, which applies to W86, lists "lightning (T75.0-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
