IVF billing uses a distinct set of CPT codes that most general medical billers rarely see in volume — and the global period and bundling rules around them are where clinics either capture full reimbursement or quietly leave revenue behind.
The core ART cycle codes
CPT codes 58970–58976 cover the assisted reproductive technology (ART) procedures that make up a treatment cycle — oocyte retrieval, gamete/embryo transfer, and related procedures. These sit inside a global period structure, which means several services delivered around the same procedure may already be bundled into a single payment — billing them separately is a denial, but failing to identify what's genuinely separate is a missed payment.
Embryology lab codes are billed differently
CPT 89250–89280 cover the embryology lab side: ICSI, assisted hatching, and related lab services. These often follow different bundling logic than the ART cycle codes themselves, and it's common for practices to under-recognize which lab services are separately billable outside the global period.
Genetic testing sits outside the bundle — usually
Preimplantation genetic testing (PGT) is frequently billed separately from the ART global period, since it's typically performed by an independent reference lab under its own coding structure. Practices that don't split this out correctly either double-bill (triggering denial) or fail to capture the referral/coordination component they're entitled to.
Three questions worth checking against your own claims
1. Is your billing team confirming ART global period boundaries per payer, not applying one blanket rule across all of them?
2. Are embryology lab codes (89250–89280) reviewed individually for bundling status, rather than defaulting to "included"?
3. Is PGT billed and coordinated as a separate service, matched to the reference lab's own billing?
Why fertility billing needs its own process
General OB-GYN or reproductive health billing experience doesn't automatically transfer to IVF-specific coding — the code density and bundling logic are different enough that a generalist process misses money on both ends: false denials from incorrect separate billing, and quiet underbilling from over-bundling. Our fertility and IVF billing page covers the fuller code set and how we handle it end to end.
