T84.6 vs Z47.2
T84.6 (Infection and inflammatory reaction due to internal fixation device) compared with Z47.2 (Encounter for removal of internal fixation device), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. Z47.2 carries an Excludes1 note covering T84.6: “infection or inflammatory reaction to internal fixation device (T84.6-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
