M48.5 vs M80.0AXA
M48.5 (Collapsed vertebra, not elsewhere classified) compared with M80.0AXA (Age-related osteoporosis with current pathological fracture, other site, initial encounter for fracture), 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. M48.5 carries an Excludes1 note covering M80.0AXA: “pathological fracture of vertebra due to osteoporosis (M80.-)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. M80.0AXA carries an Excludes1 note covering M48.5: “collapsed vertebra NOS (M48.5)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
No — do not report together. M80.0AXA carries an Excludes1 note covering M48.5: “wedging of vertebra NOS (M48.5)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
