Summary & Overview
HCPCS S4022: Assisted Oocyte Fertilization, Case Rate
HCPCS Level II code S4022 identifies a case-rate service for assisted oocyte fertilization, a bundled charge covering clinical steps involved in fertilizing oocytes with assisted reproductive techniques. This code is relevant nationally as utilization of assisted reproductive services grows and payers clarify coverage and bundled payment approaches for fertility treatments.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find an overview of how S4022 is used to capture case-rate billing for assisted oocyte fertilization, typical sites of service, and the clinical context for the procedure. The publication summarizes benchmark topics and policy considerations that payers and provider billing teams commonly review for bundled fertility services.
The report provides: definitions and clinical scope for the code; implications for coding and billing workflows in fertility clinics and outpatient reproductive medicine centers; payer coverage landscape and common areas of payer review; and guidance on where stakeholders typically seek additional documentation or policy clarity.

Clinical & Coding Specifications
Clinical Context
A 34-year-old patient with tubal factor infertility and a history of failed intrauterine insemination presents to a reproductive endocrinology and infertility (REI) clinic for assisted oocyte fertilization services. The patient has completed ovarian stimulation, transvaginal oocyte retrieval, and oocytes are available for laboratory fertilization techniques such as conventional in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). The clinic schedules an assisted oocyte fertilization case-rate encounter covering laboratory procedures required to inseminate or microinject retrieved oocytes, monitor fertilization, and provide initial embryology services for that treatment cycle.
The clinical workflow includes: pre-procedure counseling and informed consent; coordination of partner or donor sperm collection and testing; receipt and processing of oocytes in the embryology laboratory; performance of insemination or ICSI; incubation and fertilization assessment at defined time points; documentation of fertilization outcomes; and preparation of embryos for transfer or cryopreservation. Billing for this service uses the case-rate code S4022 to represent the bundled assisted oocyte fertilization services provided during that cycle. Typical site of service is an ambulatory reproductive endocrinology clinic with an on-site or affiliated embryology laboratory; portions of the service occur in the clinical procedure suite (oocyte retrieval) and the embryology laboratory (fertilization and initial embryo care).
