I96 vs K43.1
I96 (Gangrene, not elsewhere classified) compared with K43.1 (Incisional hernia with gangrene), 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 K43.1: “gangrene in hernia (K40.1, K40.4, K41.1, K41.4, K42.1, K43.1-, K44.1, K45.1, K46.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
