J38.7 vs M12
J38.7 (Other diseases of larynx) compared with M12 (Other and unspecified arthropathy), 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. M12 carries an Excludes1 note covering J38.7: “cricoarytenoid arthropathy (J38.7)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
