D86.87 vs M63
D86.87 (Sarcoid myositis) compared with M63 (Disorders of muscle in diseases classified elsewhere), 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. M63 carries an Excludes1 note covering D86.87: “myopathy in sarcoidosis (D86.87)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
