Excludes1 — never code together — inherited from T84.01
The conditions below can never be reported together with T84.012 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- periprosthetic joint implant fracture (M97.-)
Use additional code — inherited from Chapter 19
Report an additional code alongside T84.012 to fully describe the condition. T84.012 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Use additional code — inherited from T80-T88
Report an additional code alongside T84.012 to fully describe the condition. T84.012 is sequenced first.
