P03.81: Newborn affected by abnormality in fetal (intrauterine) heart rate or rhythm

Non-billable headerICD-10-CM

P03.81 is a non-billable header ICD-10-CM code for newborn affected by abnormality in fetal (intrauterine) heart rate or rhythm. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • neonatal cardiac dysrhythmia (P29.1-)

Excludes2 inherited from the categories above P03.81

Not part of this code, but both may be coded when both are present.

Written on P03: Newborn affected by other complications of labor and delivery

  • encounter for observation of newborn for suspected diseases and conditions ruled out (Z05.-)

Other codes that can never be billed with P03.81

Their own Excludes1 notes name this code, so the conflict is not listed above.

  • P00.7Newborn affected by other medical procedures on mother, not elsewhere classified
