Excludes1 — never code together — inherited from M45

The conditions below can never be reported together with M45.A on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • arthropathy in Reiter's disease (M02.3-)
  • juvenile (ankylosing) spondylitis (M08.1)

Excludes2 — not included here — inherited from Chapter 13

The conditions below are not part of M45.A, but a patient may have both at the same time. When documentation supports it, M45.A and the excluded code may both be reported.
