Summary & Overview
CPT 89337: Oocyte Cryopreservation and Storage, Technical Component
CPT code 89337 denotes the technical laboratory service to preserve and store one or more mature living oocytes at low temperatures for future reproductive use. This service is clinically important for patients facing treatments that threaten fertility, such as chemotherapy or radiation, and supports fertility preservation protocols within assisted reproductive technology (ART) programs. Nationally, coverage and billing for oocyte cryopreservation have implications for oncology-adjacent care, reproductive medicine access, and health plan benefit design.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical and billing context for CPT code 89337, comparisons of how major payers approach coverage and coding for fertility preservation services, and benchmarks where available. The publication also summarizes clinical settings where the service is delivered and highlights common modifier usage patterns. This material is intended to inform coding, billing, and policy considerations for providers and administrators involved in reproductive medicine and oncology-related fertility preservation.

Billing Code Overview
CPT code 89337 describes a laboratory service in which a lab analyst performs the technical procedures required to preserve and store one or more mature living oocytes at low temperatures for future use. This service is intended to preserve egg cells for patients at elevated risk of infertility due to medical interventions such as chemotherapy or radiation therapy.

Clinical & Coding Specifications
Clinical Context
A 32-year-old patient diagnosed with early-stage Hodgkin lymphoma elects to preserve fertility prior to gonadotoxic chemotherapy. The reproductive endocrinology and infertility (REI) team coordinates oocyte cryopreservation. The clinical workflow includes initial counseling and informed consent, baseline ovarian reserve testing (FSH, AMH, antral follicle count), ovarian stimulation using gonadotropins, serial transvaginal ultrasound and estradiol monitoring, oocyte retrieval under conscious sedation or general anesthesia, and laboratory processing. In the embryology laboratory, a qualified lab analyst performs the technical handling required to identify, evaluate, wash, and vitrify (rapid-freeze) mature metaphase II oocytes for long-term storage. The preserved oocytes are labeled, documented in the laboratory information system, placed into validated cryostorage containers, and logged with patient identifiers and storage duration instructions. Typical sites of service are outpatient hospital-based reproductive medicine centers or freestanding fertility clinics with on-site embryology laboratories and accredited cryostorage facilities. Clinical documentation includes indication for fertility preservation, informed consent for cryostorage, procedure notes for retrieval and anesthesia, laboratory records confirming number and quality of oocytes preserved, and storage consent and billing linking to 89337 for the laboratory technical service of preserving mature oocytes.
