Neonatology Billing Services
Neonatology billing centers on the sickest and smallest patients in the hospital. A newborn may begin life with a mother's insurance, move to a Medicaid plan, and finally get their own coverage, all while in the NICU. Claims must follow the right payer at the right time.
Coding is tied to the baby's age, weight, and level of care. Critical care, intensive care, and normal newborn care each use different codes, and the same baby may move between them during a stay. Neonatology billing is also tied to delivery room attendance and resuscitation. Westmont connects neonatology groups and NICU programs with vetted billing experts who know how these pieces fit together.

Billing challenges in neonatology
- Matching the code to the day and condition. Critical care, intensive care, and normal newborn codes are chosen by the baby's status that day. Billers review notes and census data so the code reflects the actual level of care.
- Birth weight and age rules. Several codes depend on weight and age in days. Billers confirm weight at the time of service, since a baby's weight changes during the stay.
- Coverage that changes. Newborns are often added to a parent's plan after birth, with a limited time window. Billers verify enrollment early and keep checking, since the correct payer may change during the stay.
- Delivery room services. Attendance and resuscitation require a request from the delivering clinician and clear documentation of what was done. Payers may also bundle these with other services. Billers check requests and notes.
- Procedures and critical care. Some bedside procedures are bundled into neonatal critical care, and others can be billed separately. Billers apply current payer and CPT guidance to avoid errors.
- Multiple providers in a group. Different neonatologists may see the same baby on a given day. Billers follow payer rules on same-day services and make sure only one provider bills for the same service.
- Medicaid and state rules. Many NICU babies are Medicaid eligible, and states vary in rules for newborns and NICU days. Billers track state policy and timely filing limits.

Frequently asked questions
How is NICU care billed by physicians?
Physicians bill by day of service using codes based on the baby's condition, age, and weight. Sicker babies may qualify for critical care codes, while recovering babies may use intensive care codes. Documentation must support the level chosen. The hospital bills facility charges separately.
What is the difference between critical care and intensive care for newborns?
Neonatal critical care applies to a critically ill infant needing constant, high-level management. Intensive care codes apply to a recovering infant who is not critical but still needs close monitoring, and they are tied to weight. Payers may audit these distinctions, so notes should clearly describe the baby's condition.
Can we bill delivery room attendance and resuscitation?
Often, yes, when the delivering clinician requests a neonatology presence and the neonatologist documents the care provided. Resuscitation has its own code. Some payers bundle or limit these services, so check payer policy and keep a clear request record.
Which insurance is billed when a baby is born?
It depends on enrollment. Babies are often covered under a parent's plan from birth if added in time, while others qualify for Medicaid. Billers verify coverage early and watch for changes. Rules and enrollment windows vary by plan and state.
Why do neonatology claims take longer to pay?
Coverage often changes during the stay, claims can be large, and payers often review NICU days. Missing birth details or weight can also delay payment. Clear documentation and early eligibility checks help claims move faster.
