E70 vs R82
E70 (Disorders of aromatic amino-acid metabolism) compared with R82 (Other and unspecified abnormal findings in urine), 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. R82 carries an Excludes1 note covering E70: “specific findings indicating disorder of amino-acid metabolism (E70-E72)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
