D86.86 vs M01

D86.86 (Sarcoid arthropathy) compared with M01 (Direct infections of joint in infectious and parasitic 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. M01 carries an Excludes1 note covering D86.86: “sarcoidosis arthritis (D86.86)”

Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
