P55 — Hemolytic disease of newborn
Is P55 billable?
No — P55 is a non-billable header code. P55 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 4 billable codes beneath P55.

Excludes1 — never code together — inherited from P50-P61
The conditions below can never be reported together with P55 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from Chapter 16
The conditions below are not part of P55, but a patient may have both at the same time. When documentation supports it, P55 and the excluded code may both be reported.
