E88.1 vs K90.81
E88.1 (Lipodystrophy, not elsewhere classified) compared with K90.81 (Whipple's disease), 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. E88.1 carries an Excludes1 note covering K90.81: “Whipple's disease (K90.81)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
