G73.7 vs M35.03
G73.7 (Myopathy in diseases classified elsewhere) compared with M35.03 (Sjögren syndrome with myopathy), 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. G73.7 carries an Excludes1 note covering M35.03: “Sjögren syndrome (M35.03)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
