T82.198A vs T82.198S
T82.198A (Other mechanical complication of other cardiac electronic device, initial encounter) compared with T82.198S (Other mechanical complication of other cardiac electronic device, sequela), from the official CMS tabular data. T82.198A and T82.198S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T82.198A and T82.198S 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.
