I'm not in California, so am not sure in regards to specific insurers. The easiest way to tell is to look at the plan documents, in the exclusions. How does it word it? For example, mine excludes Artificial Insemination and In Vitro Fertilization. Therefore, all the meds, all the bloodwork, ultrasounds, office visits, etc, are all covered. We have to pay the charge for the actual IVF procedure ourselves. That's still a lot, don't get me wrong, but it is much much less than having to pay for EVERYTHING.
If it states that in the exclusions that there is no coverage for Infertility, then they are excluding the Diagnosis, not the procedure, which means that nothing would be covered (unless your clinic billed it a different way, which depending on what you have and why, at times they can/do).
Let me know if you have other questions - I'm pretty knowledgeable when it comes to insurance.
