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 code W03
Values for category W03 Encounter: Initial, Subsequent, Sequela
  • Ainitial encounter
  • Dsubsequent encounter
  • Ssequela

Questions About W03Overview

What is the ICD-10 code for other fall on same level due to collision with another person?

W03 is the ICD-10-CM category for other fall on same level due to collision with another person, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is W03 a billable code?

No. This is a category header that groups the codes for other fall on same level due to collision with another person, and headers cannot be submitted on claims. Claims for other fall on same level due to collision with another person need a more specific code from this category, such as W03.XXXA, W03.XXXD, and W03.XXXS.

Can W03 be reported with W51?

Not as a rule. The Excludes1 note on W03 lists "collision with another person without fall (W51)". 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).
