P29.1 — Neonatal cardiac dysrhythmia
P29.1 is a non-billable header ICD-10-CM code for neonatal cardiac dysrhythmia. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 inherited from the categories above P29.1
Also inherited, and the opposite of Excludes1: these conditions are not part of P29.1, but a patient can have both, so you may code both.
Other codes that can never be billed with P29.1
These codes carry an Excludes1 note pointing at P29.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading P29.1 alone.

Risk adjustment
P29.1 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
P29.1 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
