What 34 means

The policy does not include coverage for the newborn on the claim, so the baby's services were not paid.

The payer is saying the newborn is not covered under the subscriber's policy. Many plans need the baby to be added within a set window after birth, and some plans do not offer newborn coverage at all.

If the baby was added late or is covered under another parent's plan, the claim can often be redirected or reprocessed.

Group codes seen with 34

On a remittance, 34 comes after a group code. These are the ones it is most often reported with:

• PR 34 (Patient Responsibility): The amount is assigned to the patient. Deductibles, coinsurance and copays are the everyday examples. Whether you can collect it still depends on your contract and the patient's plan.
• CO 34 (Contractual Obligation): The provider's side of the ledger. The reduction comes from the payer contract or a rule the provider has to follow, and the patient normally cannot be billed for it.

The payer chooses the group code for each adjustment, so the same reason code can appear with another group code on your remittance. Read the two together. More about group codes.

Common causes

• The parents did not add the newborn to the policy in time.
• The newborn's claims were billed under the parent who does not carry the baby's coverage.
• The policy has no newborn or dependent coverage option.

What to do next

1. Ask the parents whether the baby has been added to a policy and which one.
2. Check the payer's rules for adding a newborn and the effective date it applies.
3. Rebill under the correct policy and member ID once the baby is enrolled.
4. Look into other coverage, such as a government program, if no private plan covers the baby.
