Summary & Overview
HCPCS S4027: Storage of Previously Frozen Embryos
HCPCS Level II code S4027 represents the storage of previously frozen embryos, a component of assisted reproductive technology services. This code captures fees associated with ongoing cryostorage after embryos have been created and frozen, and it is relevant for clinics, payers, and patients managing long-term preservation costs. Nationally, embryo storage intersects with fertility coverage policies, consumer out-of-pocket considerations, and evolving payer benefit designs.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of coverage considerations and payer approaches to embryo storage claims.
This publication provides: (1) a clinical and billing context for S4027, (2) benchmarks and typical claim line characteristics where available, and (3) policy and coding notes relevant to reimbursement determinations. The content is intended to inform billing professionals, reproductive endocrinology providers, and payer policy teams about how storage of previously frozen embryos is represented in claims and where to look for further policy guidance.

Clinical & Coding Specifications
Clinical Context
A patient undergoing in vitro fertilization (IVF) has embryos that were previously created and cryopreserved. The typical scenario involves a reproductive endocrinology and infertility (REI) clinic or an assisted reproductive technology (ART) lab maintaining long-term storage for those embryos on behalf of the patient or couple. A common workflow: the patient signs a storage agreement and provides payment arrangements; the clinic documents the date embryos were placed into long-term storage after prior embryo creation and cryopreservation; the embryology laboratory logs container identification, storage tank, and cryopreservation method (vitrification or slow-freeze); periodic inventory and maintenance of storage tanks is performed; billing for ongoing storage is submitted periodically using S4027 to a payer for custody and storage of previously frozen embryos. Typical sites of service are outpatient fertility clinics, hospital-based reproductive medicine centers, or freestanding ART laboratories with cryostorage facilities. Patients commonly include individuals or couples awaiting embryo transfer, persons delaying childbearing, or those preserving embryos for fertility preservation prior to medical treatments.
