K51.01 vs R58
K51.01 (Ulcerative (chronic) pancolitis with complications) compared with R58 (Hemorrhage, not elsewhere classified), 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. R58 carries an Excludes1 note covering K51.01: “ulcerative enterocolitis with rectal bleeding (K51.01)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
