ICD-10-CM Diagnosis Code T27.4

The appropriate 7th character is to be added to each code from category T27

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

external cause code to identify the source and intent of the burn (X00 - X19, X75 - X77, X96 - X98)

external cause code to identify place (Y92)

birth trauma (P10-P15)

obstetric trauma (O70-O71)

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.
