M80.0AXA vs M84.4
M80.0AXA (Age-related osteoporosis with current pathological fracture, other site, initial encounter for fracture) compared with M84.4 (Pathological fracture, not elsewhere classified), 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. M80.0AXA carries an Excludes1 note covering M84.4: “pathological fracture NOS (M84.4)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
