ICD-10-CM — Chapter 19

Injury, poisoning and certain other consequences of external causes

Tabular List

Find your ICD-10-CM code by first selecting the most applicable chapter



Injury, poisoning and certain other consequences of external causes

Note: Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code
The chapter uses the S-section for coding different types of injuries related to single body regions and the T-section to cover injuries to unspecified body regions as well as poisoning and certain other consequences of external causes.

Use Additional code to identify any retained foreign body, if applicable (Z18.-)
