T83.428A vs T83.428S

T83.428A (Displacement of other prosthetic devices, implants and grafts of genital tract, initial encounter) compared with T83.428S (Displacement of other prosthetic devices, implants and grafts of genital tract, sequela), from the official CMS tabular data. T83.428A and T83.428S code the same injury at a different phase of treatment.

T83.428A

Initial encounter

Displacement of other prosthetic devices, implants and grafts of genital tract, initial encounter

↔

T83.428S

Sequela

Displacement of other prosthetic devices, implants and grafts of genital tract, sequela

Same underlying diagnosis, different encounter phase.

The 7th character records the phase of care for the encounter being coded, so a single encounter takes one of these characters, not several. Review whether both phases belong on the same episode of care.

Can these codes be reported together?

Same injury, other encounter phase. T83.428A and T83.428S 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.
