Can these codes be reported together?
No — do not report together. Z98.85 carries an Excludes1 note covering T86: “encounter for removal of transplanted organ -code to complication of transplanted organ (T86.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
