M43.5X9 vs M47.1
M43.5X9 (Other recurrent vertebral dislocation, site unspecified) compared with M47.1 (Other spondylosis with myelopathy), 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. M47.1 carries an Excludes1 note covering M43.5X9: “vertebral subluxation (M43.3-M43.5X9)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
