Excludes1 — never code together

The conditions below can never be reported together with J98.6 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • congenital malformation of diaphragm NEC (Q79.1)
  • congenital diaphragmatic hernia (Q79.0)

Excludes2 — not included here

The conditions below are not part of J98.6, but a patient may have both at the same time. When documentation supports it, J98.6 and the excluded code may both be reported.

  • diaphragmatic hernia (K44.-)
