FET Billing

Frozen Embryo Transfer Billing
Handled With Precision

FET billing is commonly undercoded — thaw fees missed, storage unbilled, and diagnosis codes that don't match the clinical scenario. We bill every FET component correctly from the first submission.

FET Billing Components

Representative examples only. Code selection depends on documentation and payer-specific rules.

Embryo Thaw
89352

Thawing of cryopreserved embryos — often overlooked as a separately billable service.

Embryo Transfer (FET)
58974

Frozen-thawed embryo transfer uses the same transfer code as fresh (58974) — differentiated by diagnosis code and authorization, not procedure code.

Endometrial Preparation Monitoring
76830, 82670

Transvaginal ultrasound and estradiol monitoring during FET prep — coverage depends on payer and cycle count.

Annual Embryo Storage
89342

Annual cryostorage fee — often patient-pay but should be documented and coded correctly.

Assisted Hatching
89253

When performed with FET, this is a distinct billable service — not bundled into the transfer code.

PGT on Frozen Embryos
89290, 81228

Genetic testing prior to FET — lab direct billing or coordination depending on facility arrangement.

Fertility Mandate Payer Reporting
S4016, S4017, S4018, S4037, S4040

Bundled S codes used by mandate payers such as Aetna — frozen cycle case rate, cancelled transfers, cryopreserved embryo transfer, and ongoing embryo storage monitoring.

Diagnosis Code Scenarios

ICD-10 codes are illustrative. Final code selection requires clinical documentation review.

Freeze-all IVF cycle → FET
N97.0 – N97.9 (infertility + specific etiology)
PGT-A/PGT-M cycle → FET after results
Z31.61 – Z31.69 (encounter for procreative management)
Donor egg cycle → FET
Z31.7 (encounter for procreative management, using donor oocyte)
Elective embryo banking → later FET
Z31.61 (encounter for assisted reproductive fertility procedure)
