ICD-10-CM Diagnosis Code T69.1

The appropriate 7th character is to be added to each code from category T69

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

code to identify source of exposure:

Exposure to excessive cold of man-made origin (W93)

Exposure to excessive cold of natural origin (X31)

birth trauma (P10-P15)

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.
