Non-Billable/Non-Specific Code

W92 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
The 2022 edition of ICD-10-CM W92 became effective on October 1, 2021.
This is the American ICD-10-CM version of W92 - other international versions of ICD-10 W92 may differ.

ICD-10-CM Coding Rules

W92 describes the circumstance causing an injury, not the nature of the injury.

External causes of morbidity
Note
- 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.
