T84.298A vs T84.298S
T84.298A (Other mechanical complication of internal fixation device of other bones, initial encounter) compared with T84.298S (Other mechanical complication of internal fixation device of other bones, sequela), from the official CMS tabular data. T84.298A and T84.298S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T84.298A and T84.298S 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.
