I96 vs L88
I96 (Gangrene, not elsewhere classified) compared with L88 (Pyoderma gangrenosum), 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. I96 carries an Excludes1 note covering L88: “pyoderma gangrenosum (L88)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
