Embryo Thaw (Cryopreserved Embryo)
Thawing of cryopreserved embryo(s) in preparation for transfer. Billed at the time of the FET cycle, separately from the transfer code (58976).
Billing Notes

Common Denial Reasons
- Not billed — thaw fee absorbed into FET package
- Not covered by payer (bundled under FET cycle rate)
- Missing documentation of embryo thaw
Payer Notes
Some payers cover 89352 separately; others bundle it under the FET rate. Check payer-specific coverage. Even where bundled, accurate documentation protects against audit.
