Injury, poisoning and certain other consequences of external causes (S00-T88)

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.-)

birth trauma (P10-P15)
obstetric trauma (O70-O71)

The appropriate 7th character is to be added to each code from category T69
A - initial encounter
D - subsequent encounter
S - sequela

asphyxia from other gases, fumes and vapors (T59.-)
respiratory distress (syndrome) in newborn (P22.-)
The appropriate 7th character is to be added to each code from category T71
A - initial encounter
D - subsequent encounter
S - sequela
T73 Effects of other deprivation [+]
The appropriate 7th character is to be added to each code from category T73
