M14.62 vs M36.1
M14.62 (Charcôt's joint, elbow) compared with M36.1 (Arthropathy in neoplastic disease), 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. M14.62 carries an Excludes1 note covering M36.1: “neoplastic disease (M36.1)”
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. M36.1 carries an Excludes2 note covering M14.62: “arthropathies in diseases classified elsewhere (M14.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
