T83.719A vs T83.719S
T83.719A (Erosion of other prosthetic materials to surrounding organ or tissue, initial encounter) compared with T83.719S (Erosion of other prosthetic materials to surrounding organ or tissue, sequela), from the official CMS tabular data. T83.719A and T83.719S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T83.719A and T83.719S 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.
