“My insurance covers infertility” and “my insurance covers the specific treatment plan my RE just recommended” are two very different statements, and the gap between them is where a lot of patients get an unwelcome financial surprise mid-cycle. A verification of benefits, VOB for short, is the process that closes that gap. Here's how to actually do it well.

A note on this guide: Insurance plans vary enormously, even within the same insurer, based on your specific employer's plan design. This article describes the general VOB process; your specific coverage details always come from your plan documents and a direct benefits verification, not from general guidance like this.

What a verification of benefits actually checks

A thorough VOB goes well beyond confirming that "infertility" appears somewhere on your policy. It should specifically confirm:

  • Diagnostic testing coverage, separate from treatment coverage; many plans cover diagnostic workups even when they exclude treatment
  • Treatment-specific coverage, IUI, IVF, ICSI, and genetic testing are often covered differently, sometimes with entirely separate authorization requirements
  • Lifetime or annual maximums, either in dollars or number of covered cycles
  • Medication coverage, often handled through a separate pharmacy benefit with its own deductible and prior authorization process
  • Whether your specific clinic and RE are in-network, and if not, what your out-of-network benefit actually pays
  • Any pre-authorization or step-therapy requirements, such as being required to complete a certain number of IUI cycles before IVF is covered

Who actually does this work

Most fertility clinics have a dedicated financial counselor or insurance coordinator whose job is running VOBs for incoming patients. This is usually a real service worth using, they know the specific coding and authorization quirks of major regional insurers. That said, their VOB is still worth double-checking against your own read of your plan documents, since clinic financial counselors are working from what your insurer tells them over the phone, which isn't always complete or accurate.

Why calling your insurer yourself still matters

Insurance representatives on a general member services line often aren't fertility specialists and may give incomplete answers to specific procedural questions. When you call, ask to speak with someone who handles infertility or reproductive benefits specifically if your insurer has that option, and always get a reference number for the call along with the representative's name.

A practical VOB checklist

  1. Get your plan's Summary Plan Description (SPD), not just the member handbook, this is the legally binding document that governs what's actually covered.
  2. Search the SPD specifically for "infertility," "assisted reproductive technology," and "ART", coverage details are often buried in an exclusions or riders section, not the main benefits summary.
  3. Call your insurer directly and ask specifically about IUI, IVF, ICSI, genetic testing, and fertility medication coverage as separate line items, not one combined "infertility" question.
  4. Ask about pre-authorization requirements and get the specific process and timeline in writing if possible.
  5. Confirm network status for your specific clinic, RE, and the lab your embryos would be processed through, these aren't always the same entity.
  6. Get everything in writing where possible, an email summary from either your insurer or your clinic's financial counselor is worth far more than a verbal phone confirmation if a dispute comes up later.
If your employer offers a fertility benefits manager

If your employer works with a dedicated fertility benefits platform like Progyny, Carrot, or Maven, your VOB process usually runs through that platform rather than your general medical insurer, and tends to be considerably more transparent, since these platforms specialize specifically in fertility benefit navigation. Check with your HR team about whether this applies to you before assuming your standard medical insurer is the only source of coverage.

Frequently asked questions

What's the difference between a VOB and prior authorization?

A VOB confirms what your plan theoretically covers and under what conditions. Prior authorization is a separate, specific approval your clinic must obtain from your insurer before a particular treatment or medication is covered, even if your VOB confirmed general coverage exists.

How long does a VOB take?

This varies significantly by insurer, anywhere from same-day to two weeks. If you're on a tight treatment timeline, ask your clinic's financial counselor to flag your case as time-sensitive and follow up proactively rather than waiting passively.

What if my clinic's VOB and my own research disagree?

This is worth resolving before treatment starts, not after a claim is denied. Request a three-way call with your clinic's financial counselor and your insurer if needed, and keep detailed notes, including dates, names, and reference numbers, of every conversation.
