Excludes1 — never code together — inherited from Z97
The conditions below can never be reported together with Z97.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- complications of internal prosthetic devices, implants and grafts (T82-T85)
Excludes2 — not included here — inherited from Z97
