Duke and Carsyn Pond spent a little over two months in the neonatal intensive care unit after being born at 32 weeks, and now, at 2 years old, their parents are staring down more than $1 million in medical debt tied to an obscure insurance rule that assigns coverage based on whose birthday falls earlier in the year.
Kelsey Pond and Travis Pond had planned to put the twins on Kelsey's insurance, and she placed Travis's insurance on file at the hospital as a backup, according to CBS Colorado, whose investigation, reported by Karen Morfitt, examined multiple insured families hit with massive bills after their babies needed neonatal intensive care. Because Colorado's so-called birthday rule assigns a newborn to the policy of the parent whose birthday comes first in the calendar year, it made Travis the primary policyholder instead — a fact the family didn't realize would matter until the bills started arriving.
Duke was flown to Children's Hospital Colorado and underwent surgery while in the NICU; Carsyn followed him there soon after. Kelsey's insurance company was billed first and initially paid claims for one twin, but the outlet reports that the insurer later reversed those payments once higher-cost NICU claims triggered the birthday rule for the other twin. Travis's insurer, in turn, denied the claims because they were not filed on time, according to CBS Colorado's reporting. The result: a half-million-dollar bill for each baby, Travis Pond told the station, with at least one bill already sent to collections.
A Rule Built for Insurers, Not Families
Colorado's birthday rule traces back to a national framework created by the National Association of Insurance Commissioners to give carriers a uniform, neutral way to decide which plan pays first when a child is covered by both parents' insurance, according to eHealth. In Colorado, that standard is codified in state regulation 3 CCR 702-4-6-2-6, which directs that when a child is covered under two non-divorced parents' plans, the parent whose birthday falls earlier in the calendar year becomes the primary payer, per Cornell Law School's published text of the rule. The rule only applies when parents are covered by different insurance providers, and per guidance from the American Dental Association, coordination-of-benefits provisions like it are triggered only when a dependent is enrolled in two separate group health plans at once.
The Ponds are not alone. CBS Colorado's reporting describes multiple families reporting similar insurance issues after their children required neonatal intensive care, including one mother whose twins included a child needing NICU care. Denver station KUSA-TV separately reported in July on Megan and Benjamin Peer, who faced $540,000 in NICU bills at UCHealth after UnitedHealthcare initially paid claims and then retroactively clawed back the funds under the same birthday rule.
Hospitals and Insurers Point Elsewhere
Children's Hospital Colorado said its teams are reviewing and investigating concerns in the Pond family's situation. CU Medicine said it contacts patients when insurers reverse payments or disagree on policy. Advent Hospital said coordination of benefits is a matter between insurance companies, adding that insurers are best positioned to address the claims. Cigna said it remains available to work directly with patients to review and resolve outstanding medical bills, while Blue Cross Blue Shield of Texas said it has a standing policy not to discuss clients. CBS Colorado said it contacted the hospitals and insurance companies involved in its reporting.
Kelsey Pond says what she wants most is simple: for insurers and the hospital to actually agree on who is responsible for paying the claims, rather than leaving her family caught between them with a bill north of $1 million.
Lawmakers and Regulators Weigh Changes
The cases have raised questions about whether Colorado should change the birthday rule altogether. The Colorado Division of Insurance is examining whether the rule should be revised, though that review is still in its early stages. According to CBS News, the division has floated giving parents a 30-day window to actively designate primary coverage for a newborn instead of defaulting to birth dates — separate from Colorado's existing 30-day rule, which already allows parents to add newborns to health insurance within that window.
Democratic State Rep. Kyle Brown, who previously served as deputy director of the Colorado Division of Insurance, according to LegiStorm, said the birthday rule is not protecting people and is leaving them with large bills. Brown said the cases warrant attention from legislators, and suggested lawmakers could draft legislation or work with agency counterparts on a fix. But he cautioned there is no simple solution: requiring parents to actively designate a plan could create bigger problems if they forget to do so, he said, and he added that insurers using discretion in applying the state's regulation would itself be concerning.
Any fix Colorado lawmakers pursue would face a hard legal ceiling. Under the federal Employee Retirement Income Security Act, self-insured employer health plans are preempted from state insurance mandates, meaning a state law change would not automatically apply to self-funded corporate benefit plans, according to insurance brokerage Newfront. That leaves open the possibility that even a revised birthday rule could not fully protect every insured family in the state.
The Financial Stakes of a NICU Stay
The dollar figures at the center of the Ponds' dispute are not unusual for extended neonatal care. Hospital charges for Level III neonatal intensive care commonly run $5,000 to $8,000 per day, while high-acuity Level IV surgical care can top $10,000 daily, according to cost analysis published by CareRoute. Industry claims data published by PartnerRe found that national NICU admissions rose 13% between 2016 and 2023, with average admission costs reaching $70,000 and complex cases routinely exceeding $1 million.
Twin pregnancies carry an outsized share of that risk. More than half of twin pregnancies result in premature delivery before 37 weeks of gestation, according to Johns Hopkins Medicine clinical data, which sharply raises the odds of a multi-week NICU stay of the kind Duke and Carsyn required. For families like the Ponds, that medical reality collided with an administrative rule never designed with a seven-figure bill in mind — and now sits at the center of a debate over whether Colorado can fix it before the next family gets caught in the same gap.
