T82.512A vs T82.512S
T82.512A (Breakdown (mechanical) of artificial heart, initial encounter) compared with T82.512S (Breakdown (mechanical) of artificial heart, sequela), from the official CMS tabular data. T82.512A and T82.512S code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T82.512A and T82.512S 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.
