Excludes1 — never code together — inherited from Q50-Q56

The conditions below can never be reported together with Q51.6 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

syndromes associated with anomalies in the number and form of chromosomes (Q90-Q99)

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of Q51.6, but a patient may have both at the same time. When documentation supports it, Q51.6 and the excluded code may both be reported.

inborn errors of metabolism (E70-E88)
