N23 vs R10
N23 (Unspecified renal colic) compared with R10 (Abdominal and pelvic pain), 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. R10 carries an Excludes1 note covering N23: “renal colic (N23)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
