R00 — Abnormalities of heart beat
Is R00 billable?
No — R00 is a non-billable header code. R00 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 5 billable codes beneath R00.

Excludes1 — never code together
The conditions below can never be reported together with R00 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- abnormalities originating in the perinatal period (P29.1-)
Excludes2 — not included here
The conditions below are not part of R00, but a patient may have both at the same time. When documentation supports it, R00 and the excluded code may both be reported.
- specified arrhythmias (I47-I49)
Excludes2 — not included here — inherited from Chapter 18
The conditions below are not part of R00, but a patient may have both at the same time. When documentation supports it, R00 and the excluded code may both be reported.
