K80 vs K82.0
K80 (Cholelithiasis) compared with K82.0 (Obstruction of gallbladder), 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. K82.0 carries an Excludes1 note covering K80: “obstruction of gallbladder with cholelithiasis (K80.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
