Q24 — Other congenital malformations of heart
Is Q24 billable?
No — Q24 is a non-billable header code. Q24 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 9 billable codes beneath Q24.

Excludes1 — never code together
The conditions below can never be reported together with Q24 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- endocardial fibroelastosis (I42.4)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of Q24, but a patient may have both at the same time. When documentation supports it, Q24 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)

How long has Q24 existed?
Q24 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
Which codes are confused with Q24?
ICD-10-CM declares these codes mutually exclusive with Q24 — exactly one of each pair can be correct for a given encounter.
