Excludes1 — never code together
The conditions below can never be reported together with Q77 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- mucopolysaccharidosis (E76.0-E76.3)
Excludes2 — not included here
The conditions below are not part of Q77, but a patient may have both at the same time. When documentation supports it, Q77 and the excluded code may both be reported.
- congenital myotonic chondrodystrophy (G71.13)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q77, but a patient may have both at the same time. When documentation supports it, Q77 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
