Summary & Overview
CPT 89253: Assisted Embryo Hatching, Partial Zona Dissection
CPT code 89253 denotes an assisted embryo hatching procedure using a microtechnique such as partial zona dissection to enhance embryo implantation potential. This embryology laboratory service is a component of assisted reproductive technology (ART) cycles and is relevant to fertility clinics, reproductive endocrinology practices, and payers covering infertility services. Nationally, use of assisted hatching is tracked as part of ART service utilization and can affect clinical workflow, billing practices, and coverage determinations.
Key payers assessed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, common payer coverage considerations, and benchmarking topics relevant to coding and claims submission. The publication outlines standard settings where the procedure is performed, summarizes typical billing modifiers and service-line implications, and highlights areas where policy updates or payer guidance can influence reimbursement and prior authorization practices.
The report provides compact benchmarks for utilization and reimbursement trends, policy and coverage notes that affect coding application, and clinical context to inform coding accuracy and claims submission for ART programs. Data not available in the input is identified where applicable.
Billing Code Overview
CPT code 89253 describes an assisted embryo hatching procedure in which the analyst uses a microtechnique, such as partial zona dissection, to facilitate embryo implantation. The service type is an assisted reproductive technology procedure focused on embryology laboratory manipulation. The typical site of service is an outpatient fertility clinic or specialized embryology laboratory associated with an assisted reproduction program.

Clinical & Coding Specifications
Clinical Context
A 36-year-old patient with a history of prior failed in vitro fertilization (IVF) cycles and advanced maternal age undergoes an assisted embryo hatching procedure to improve implantation potential. The procedure is performed in an assisted reproductive technology (ART) laboratory by an embryology analyst using a microtechnique such as partial zona dissection under an inverted microscope. Typical workflow: oocyte retrieval and fertilization occur in the ART clinic; embryos are cultured to cleavage or blastocyst stage; the embryology team evaluates embryo quality and determines assisted hatching is indicated (for example, thickened zona pellucida or previous implantation failure); the analyst performs 89253 on selected embryos using microtools or laser-assisted techniques as specified by lab protocol; treated embryos are returned to culture and subsequently transferred or cryopreserved according to the patient’s treatment plan. Usual site of service is an outpatient fertility center’s embryology laboratory within a hospital-based or independent reproductive medicine facility. The patient encounter is typically scheduled and billed under ART laboratory services coordinated with the reproductive endocrinology team.
