Laboratory — Cryopreservation
89258
Embryo Cryopreservation (Freeze)
Cryopreservation of embryo(s) — the freezing of one or more embryos for future use. Used for freeze-all IVF cycles, surplus embryos after fresh transfer, and PGT cycles where all embryos are frozen pending results.
Billing Notes
89258 is for embryo freezing only. Use 89337 for oocyte (egg) cryopreservation. Use 89259 for sperm cryopreservation. Annual cryostorage is separately billed with 89342 (embryos) or 89344 (oocytes).
Diagnosis Codes
N97.x (infertility), Z31.61 (ART encounter)
Common Denial Reasons
- Wrong cryopreservation code (89258 vs 89337)
- Not covered as a standalone service — bundled under cycle rate
- Annual storage not billed separately (revenue loss)
Payer Notes
Many payers bundle embryo freezing into the IVF cycle rate. Annual storage fees are typically patient-pay but should be coded correctly when billed to insurance.
