M50.1 vs M54.13
M50.1 (Cervical disc disorder with radiculopathy) compared with M54.13 (Radiculopathy, cervicothoracic region), 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. M50.1 carries an Excludes2 note covering M54.13: “brachial radiculitis NOS (M54.13)”
Excludes2 marks distinct conditions — both may be reported when both are documented.
No — do not report together. M54.13 carries an Excludes1 note covering M50.1: “radiculopathy with cervical disc disorder (M50.1)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
