M48.40XG vs M80
M48.40XG (Fatigue fracture of vertebra, site unspecified, subsequent encounter for fracture with delayed healing) compared with M80 (Osteoporosis with current pathological 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. M48.40XG carries an Excludes1 note covering M80: “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).
