What makes neonatology billing services different
Neonatology billing services are critical-care billing for the smallest patients, under the strictest documentation rules in medicine. NICU days are billed by level of care and by the infant's present body weight, delivery attendance and resuscitation have their own codes, and ventilator management is reported separately by day. Fastora provides neonatology medical billing for neonatology groups, NICU programs and children's hospitals, built around daily level-of-care coding, weight-tier accuracy, attending-versus-consulting splits and the Medicaid-heavy payer mix that defines newborn care. A neonatology billing company lives in the daily note — every day's level of care has to be coded from that day's record.
The core discipline is matching each calendar day to the right code: normal newborn, intensive observation, subsequent intensive care by weight tier, or neonatal critical care. Our medical billing services for neonatology groups code from the daily note, not from a template.
Newborn, intensive and critical care: the daily code decision
| Situation | Representative codes | Billing note |
|---|---|---|
| Normal newborn care | 99460–99463 | History, exam and discharge-day management per day |
| Attendance at delivery | 99464 | Requested by the delivering physician |
| Delivery/birthing room resuscitation | 99465 | Beyond routine attendance; ventilation or intubation |
| Initial intensive observation, neonate 28 days or younger | 99477 | Requires intensive observation but not critical care |
| Initial neonatal critical care | 99468 | Critically ill neonate, 28 days or younger |
| Subsequent neonatal critical care | 99469 | Per day of continued critical care |
The line between 99477 and 99468 is clinical and must be in the note: intensive observation versus critical illness with organ-system failure or imminent failure. We review the daily documentation against the reported level before the claim is filed, since level-of-care upcoding in the NICU is a known audit focus.
Weight-tiered intensive care days
Subsequent intensive-care days for very small infants are reported by present body weight tier — 99478, 99479 and 99480 for the smallest weight bands — and the weight has to be the current weight, not the birth weight, documented for that day. A single-day weight error puts the claim in the wrong tier.
We reconcile the reported tier to the day's documented weight at charge entry, so weight-tier claims always match the record. Discharge-day and admission-day rules for these codes are checked against the daily census before submission.
Delivery attendance, resuscitation and ventilator days
Delivery attendance requested by the delivering physician is reported with 99464; when resuscitation beyond routine care is required — positive-pressure ventilation, intubation, chest compressions or medications — 99465 applies. The delivery record must show what was done and why, because payers routinely request it.
Initial and continuing ventilator management is reported per day with 94002–94004, separate from the level-of-care codes. We make sure ventilator days reconcile to the respiratory-therapy documentation so the count is right on both sides.
Transfers, transports and shared coverage
NICU stays involve transfers — from the delivery hospital to a higher-level NICU, between facilities, and attending-physician handoffs. Each transfer creates its own admission-date, place-of-service and attending questions, and transport services are billed separately from the daily care.
When two neonatologists cover the same infant — attending and consulting — only one reports the daily critical or intensive care code, and the roles have to be clear in the record. We confirm attending-versus-consulting status before coding so the same day is never billed twice.
Medicaid-heavy payer mix and newborn enrollment
Newborn care is disproportionately Medicaid, and Medicaid timely-filing limits, newborn enrollment timing and managed-care authorization rules vary by state. A newborn covered under the mother's Medicaid eligibility still needs the enrollment and the claim filed correctly and on time.
We run eligibility and benefits checks at admission and track newborn Medicaid enrollment, so claims are not lost to enrollment timing or missed filing windows.
Common neonatology billing denials and how we prevent them
| Denial | Typical cause | Prevention step |
|---|---|---|
| Level-of-care mismatch | Note does not support critical vs intensive level | Daily note reviewed against reported level |
| Weight-tier error | Birth weight used instead of current weight | Current weight reconciled at charge entry |
| Duplicate daily code | Attending and consultant both bill the day | Roles confirmed before coding |
| Resuscitation denied | Delivery record lacks detail | Delivery documentation checked at charge entry |
| Timely filing | Medicaid enrollment delay | Enrollment tracked; claims filed within window |
Every claim passes our Advanced Pre-Submission Claim Review before submission. Denials that still occur are worked by our denial management team, corrected and resubmitted or appealed with the record.
Credentialing for neonatology groups
Neonatologists, neonatal nurse practitioners and physician assistants each need enrollment with the Medicaid plans and commercial plans they bill, linked to the group and the facility before their services pay.
Our credentialing and enrollment service tracks each file through a nine-stage process, from document collection and NPI and CAQH setup to payer applications, follow-ups and final approval.
