Z49.0 vs Z99.2
Z49.0 (Preparatory care for renal dialysis) compared with Z99.2 (Dependence on renal dialysis), 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. Z99.2 carries an Excludes1 note covering Z49.0: “encounter for fitting and adjustment of dialysis catheter (Z49.0-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
