M14.641 vs M36.3
M14.641 (Charcôt's joint, right hand) compared with M36.3 (Arthropathy in other blood disorders), 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. M14.641 carries an Excludes1 note covering M36.3: “hematological disorders (M36.2-M36.3)”
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. M36.3 carries an Excludes2 note covering M14.641: “arthropathies in diseases classified elsewhere (M14.-)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
