ICD-10-CM Diagnosis Code S27.309

The appropriate 7th character is to be added to each code from category S27

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

any associated open wound of thorax (S21.-)

birth trauma (P10-P15)

obstetric trauma (O70-O71)

injury of cervical esophagus (S10-S19)

injury of trachea (cervical) (S10-S19)

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.
