What should have been a fragile but hopeful recovery for a Colorado family turned into a high-stakes insurance standoff after their premature baby’s seven-week stay in the NICU landed squarely in the middle of a fight over who pays. Benjamin was delivered by emergency C-section at 29 weeks and treated at the University of Colorado Hospital, his parents say. While they focused on keeping their son alive, payments were quietly reversed in the background, and the family suddenly found itself staring down potential bills climbing into the hundreds of thousands of dollars.
According to 9News, the parents added Benjamin to the mother’s UnitedHealthcare plan within days of his birth, and that insurer initially covered NICU charges. Months later, UnitedHealthcare clawed back roughly $400,000 in hospital payments and about $150,000 in physician payments. Anthem, which also covered the family, initially denied being the primary plan, saying it did not have the medical records it needed. UCHealth told reporters it had not billed the family and was working to get records to Anthem, and Anthem later agreed to cover CU Medicine bills, according to the report.
How the birthday rule decides who pays
Colorado’s coordination-of-benefits rules use what is known as the birthday rule to decide whose insurance is primary for a child covered under both parents’ plans. The parent whose birthday falls earlier in the calendar year is treated as the primary insurer for a dependent child, based only on month and day. The policy is laid out in the state’s coordination-of-benefits regulation, which defines "birthday" and spells out the order in which plans are supposed to pay. Legal experts say that the framework can leave families with little practical ability to choose the plan with stronger NICU coverage when a baby unexpectedly needs an extended hospital stay.
Regulators weigh a fix
The Colorado Division of Insurance is reviewing whether parents should be allowed to choose which plan is primary for a newborn during the first 30 days, a potential change regulators began studying after cases like this one drew public attention, according to CBS Colorado. State officials describe the review as a transparency and consumer-protection issue that tends to surface when high-cost newborn care is on the line. Any shift in the rules would take time, so for now, families are stuck working through disputes under the existing system while hospitals and insurance companies trade paperwork.
What parents can do now
Federal special-enrollment rules give parents short windows to add a newborn and require coverage to be retroactive to the date of birth if enrollment happens within that period. According to LegalClarity, employer plans generally allow at least 30 days and Marketplace plans 60 days to add a baby. Experts advise enrolling as quickly as possible and keeping written confirmation from both insurers and the hospital. Parents and hospitals are urged to hang on to discharge paperwork, enrollment receipts, and medical-record requests, and to push carriers for written acknowledgments to lower the risk of coordination-of-benefits showdowns later.
Legal and billing stakes
When an insurer reprocesses claims under coordination-of-benefits rules, it can recover amounts it has already paid, sometimes called a "clawback," which sends money back to hospitals and can leave families trying to sort out appeals. Colorado’s regulation allows plans to reduce or recover benefits when another plan should have been primary, so accurate enrollment dates and timely record transfers often decide who ultimately pays. Families who cannot resolve a dispute directly with insurers can file complaints with the Division of Insurance and pursue external review through state and federal appeal processes.
Megan Peer told CBS Colorado the billing fight "takes away from the limited time we have with our son," and the couple says they hope the spotlight on their case nudges insurers and regulators toward clearer, more parent-friendly procedures. For now, parents, providers, and insurance companies are still trading appeals and documentation while regulators decide whether Colorado’s birthday rule needs a rewrite.
