Assisted Embryo Hatching
Assisted embryo hatching — mechanical, chemical, or laser thinning of the zona pellucida to facilitate embryo implantation. Performed before embryo transfer in select clinical scenarios.
Billing Notes
Assisted hatching is not routinely covered by all payers. Common indications are thickened zona, recurrent implantation failure, poor prognosis cycles, and FET cycles. Document the clinical rationale in the procedure note.
Diagnosis Codes
N97.x (infertility), Z31.61 (ART encounter)
Common Denial Reasons
- Not covered by payer — requires appeal with clinical indication
- Not separately covered when bundled under cycle rate
- Missing clinical documentation for medical necessity
Payer Notes
Coverage varies widely. Progyny, for example, covers assisted hatching as part of the cycle rate. Traditional insurers may require separate auth or consider it experimental. Verify before billing.
