Bringing a new life into the world is a miracle. But when that miracle multiplies—twins, triplets, or more—it becomes even more special and complicated from the billing point of view.
Tiny babies, massive bills—don’t let the size fool you.
Preterm and low-birthweight infants attract substantial healthcare costs in the U.S., and billing for their care is anything but simple. A study of over 763,000 infants with commercial insurance through Aetna showed a total of $8.4 billion spent on neonatal care in just the first six months of life. Preterm babies cost around $76,153 on average, while low-birthweight infants reached an average of $114,437. The smallest and most premature—those born at 24 weeks—cost over $600,000 each.
The majority of these infants often require intensive care, and services overlap when they need services from multiple specialties. Things become more puzzling when more than one baby is born in one obstetric encounter as each infant needs the specific medical chart, care plan and cost planning, thus creating a complex neonatology billing maze for you. These cases always demand precise documentation, correct codes, and seamless coordination to minimize the potential for expensive errors. While neonatal care is critical to survival, the complexity and cost of billing for multiples make it one of the most challenging areas in medical billing today.
It’s time to understand what neonatal care really means and why billing for these little fighters is a whole different kind of story!
What is neonatal care?
Neonatal care is special care given to newborns, usually during their first 28 days. While not all babies need it, those born early or with health issues often do and those infants are treated in Neonatal Intensive Care Units (NICUs), which are equipped with advanced equipment and expert staff like neonatologists, nurses, and therapists. Breathing support, IV nutrition, blood transfusions, infection treatment, temperature regulation, and monitoring vital signs are some of the frequently performed neonatal services. Some babies may also need surgery, phototherapy for jaundice, or care for heart or lung problems, thus requiring each service to be tailored to the baby’s condition.
What makes neonatology billing services complicated?
Neonatal billing is complex, even for one baby. There are many CPT codes involved, along with daily notes, evaluations, procedures, respiratory care, and sometimes, even surgeries. Multiple providers like neonatologists, pediatricians, and therapists each bill separately. Everything must be coded correctly, with exact timelines and modifiers. Now imagine doing this for twins, triplets, or more. Each baby is a separate patient with their own chart, diagnosis, and care plan. When a mother delivers multiples, the billing process becomes even more complicated and demanding.
The following are the reasons that make a neonatology billing solution a hard nut to crack as compared to other specialties.
Multiple claims for one delivery:
For one delivery with triplets, you may need 15 to 20 separate claims. Things can be challenging to manage when each baby gets an initial checkup, NICU care, and needs supervision from different providers. Your administrative team needs to code daily services for each baby. The confusion is easy to imagine as even one single delivery can unleash a flood of paperwork and overlapping invoices.
Overlapping providers:
Multiple providers may treat the same baby on the same day in a NICU. For example, you may provide critical care, a cardiologist may check for heart murmurs, and a respiratory therapist may manage breathing support. Heart murmurs in newborns can be signs of serious issues like congenital heart defects, so they require close attention, tests, and follow-up care. Now just multiply this by three babies, and you get many overlapping services in one day. Without accurate notes, meticulous charge capture and correct billing codes, insurance may reject these claims as duplicates, even when every service was real and needed.
Identical diagnoses do not mean identical billing:
Twins may seem like they would have similar medical records, but billing is very different. Even though both the babies are premature and stay in the NICU, their care is rarely the same. One baby may stay longer, need different treatments, or respond differently to care. Their birth dates, discharge times, procedures, and medications can all be different. Each detail must be tracked and billed separately.
Difficulties in assigning modifiers and identifiers:
Billing for multiples needs careful use of modifiers to show that each baby received a different service. For example, Modifier 25 is used for separate services on the same day, and Modifier 59 separates services that look similar. It’s also important to use the correct provider NPI and make sure each baby’s ID is accurate. Even a small mistake—like mixing up baby A with baby B—can lead to claim denials or insurance audits.
Levels of NICU and daily billing:
NICU services are billed every day using CPT codes 99468 to 99476 for critical and intensive care. Each level of care has its own billing rate. Level III and IV NICUs pay more but are checked more closely. Your administrative team needs to record and code each baby’s stay, conditions and treatments. The 30 days staying period for triplets means managing 90 NICU service claims.
Handling billing for multiples is a full-time job. Outsourcing to a professional neonatology billing service helps ease the burden. Here’s how they make your life easier.

How a professional neonatology billing service helps you
A professional neonatology billing solution providing team knows how to treat each baby as a separate case. They assign the right patient ID, separate the claims, and track each baby’s NICU stay individually. This avoids mix-ups and overlapping errors.
Billing experts also know how to use the right modifiers to stop denials. They know which CPT codes go together, which modifiers to use for same-day services, and how to explain claims clearly to insurance. This helps reduce rejections.
Billing companies also work closely with NICU teams. They collect documents daily, make sure notes are signed, and match services with the right codes. This avoids delays and lost payments. Even when problems happen, billing experts are ready to address them promptly. They track denials, know the rules of each payer, and send strong appeals when needed. In other words, they don’t just send bills—they fight to get you paid.
