E71.3 vs G37.0
E71.3 (Disorders of fatty-acid metabolism) compared with G37.0 (Diffuse sclerosis of central nervous system), 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. E71.3 carries an Excludes1 note covering G37.0: “Schilder's disease (G37.0)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
