I have the same plan. An egg retrieval should be:
$30 for the anesthesia
Co-insurance for the insemination (it depends on how many eggs there are)
The full facility fee (about $800 is the allowed amount) until you reach your deductible, and then $75
Doctor charge should be covered 100%
If they're saying your claim for the facility fee is denied, then the only thing I can think of is you didn't have pre-authorization for the procedure.
