M43 vs Q76.2
M43 (Other deforming dorsopathies) compared with Q76.2 (Congenital spondylolisthesis), 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. M43 carries an Excludes1 note covering Q76.2: “congenital spondylolysis and spondylolisthesis (Q76.2)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
