T84.1 vs T85.612
T84.1 (Mechanical complication of internal fixation device of bones of limb) compared with T85.612 (Breakdown (mechanical) of permanent sutures), 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. T85.612 carries an Excludes1 note covering T84.1: “mechanical complication of permanent (wire) suture used in bone repair (T84.1-T84.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
