M48.57XA (Collapsed vertebra, not elsewhere classified, lumbosacral region, initial encounter for fracture) compared with M84.58 (Pathological fracture in neoplastic disease, other specified site), 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. M48.57XA carries an Excludes1 note covering M84.58: “pathological fracture of vertebra due to neoplasm (M84.58)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
