T75.838A vs T75.838S
T75.838A (Effects of other war theater, initial encounter) compared with T75.838S (Effects of other war theater, sequela), from the official CMS tabular data. T75.838A and T75.838S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T75.838A and T75.838S code the same injury at a different phase of treatment, set by the 7th character.
The 7th character records the type of care given at the encounter being coded (ICD-10-CM Official Guidelines, Section I.C.19.a), so one encounter takes one of these, not both.
