How is M43.5 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to M43.5. They show the wording a clinician may have documented, which often differs from the Tabular description.

The conditions below can never be reported together with M43.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • biomechanical lesions NEC (M99.-)

Excludes1 — never code together — inherited from M43

The conditions below can never be reported together with M43.5 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
