T84.498A vs T84.498D
T84.498A (Other mechanical complication of other internal orthopedic devices, implants and grafts, initial encounter) compared with T84.498D (Other mechanical complication of other internal orthopedic devices, implants and grafts, subsequent encounter), from the official CMS tabular data. T84.498A and T84.498D code the same injury at a different phase of treatment.
Can these codes be reported together?
Same injury, other encounter phase. T84.498A and T84.498D 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.
