CO-128 Denial Code: Newborn services in mother's allowance
Routine newborn care is bundled into the payment for the mother's delivery claim — no separate payment for the baby's routine services.
Why CO-128 happens
- ●Well-newborn care billed separately where the plan bundles it with the delivery
How to fix a CO-128 denial
- 1
If the newborn required non-routine care (NICU, illness), rebill under the newborn with supporting diagnoses
- 2
Routine care: write off per the bundling rule
How to prevent it
Split routine vs sick-newborn billing paths in your charge workflows.
