M10 vs M1A.20X0
M10 (Gout) compared with M1A.20X0 (Drug-induced chronic gout, unspecified site, without tophus (tophi)), 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?
Yes, when both are documented. M10 carries an Excludes2 note covering M1A.20X0: “chronic gout (M1A.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
No — do not report together. M1A.20X0 carries an Excludes1 note covering M10: “gout NOS (M10.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
Yes, when both are documented. M1A.20X0 carries an Excludes2 note covering M10: “acute gout (M10.-)”
