I89.0 vs I97.2
I89.0 (Lymphedema, not elsewhere classified) compared with I97.2 (Postmastectomy lymphedema syndrome), 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. I89.0 carries an Excludes1 note covering I97.2: “postmastectomy lymphedema (I97.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
