E72.3 vs G60.1
E72.3 (Disorders of lysine and hydroxylysine metabolism) compared with G60.1 (Refsum's disease), 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. E72.3 carries an Excludes1 note covering G60.1: “Refsum's disease (G60.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
