Official Description

Culture of oocyte(s)/embryo(s), less than 4 days;

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 89250 refers to the culture of oocyte(s) or embryo(s) that occurs within a timeframe of less than four days. This procedure is typically performed following a separately reportable retrieval of ova, which can be accomplished through laparoscopic or other techniques. During this process, the oocytes, which are the female reproductive cells, or embryos, which are fertilized oocytes, are carefully identified and isolated. Once isolated, they are placed in a culture medium and incubated under meticulously controlled conditions to ensure their viability and functionality prior to implantation into the uterus. If the retrieved oocytes are not fully mature, they are placed in the culture medium to allow for maturation. Conversely, if the oocytes are determined to be mature, they undergo fertilization in a separately reportable insemination procedure. Following fertilization, the resulting embryos are monitored for a period of less than four days as they develop. The standard culturing techniques utilized in this procedure are specifically outlined under CPT® Code 89250. It is important to note that there is a related procedure, CPT® Code 89251, which involves co-culturing techniques. Co-culture refers to the process of culturing oocytes or embryos alongside oviductal, uterine, granulosa, or other substrate cells. This technique requires the isolation and examination of substrate cells, which are then plated and co-cultured with the oocytes or embryos. Co-culture techniques are generally employed when 10 or more oocytes are harvested, while the typical patient undergoing this procedure has eight or fewer mature oocytes available for microfertilization. Additional work, including co-culture, is necessitated when more than 10 mature oocytes are present.

1. Indications

The procedure associated with CPT® Code 89250 is indicated for the following:

  • Oocyte Retrieval This procedure is performed after the retrieval of ova, which may be conducted through laparoscopic or other techniques.
  • Embryo Development Monitoring It is indicated for monitoring the development of embryos for less than four days post-fertilization.
  • Maturation of Oocytes The procedure is indicated when oocytes are not fully mature and require additional time in culture to mature before fertilization.
  • Fertilization Readiness It is indicated for cases where mature oocytes are available for fertilization in a separately reportable insemination procedure.

2. Procedure

The procedure for CPT® Code 89250 involves several key steps that ensure the successful culture of oocyte(s) or embryo(s).

  • Step 1: Identification and Isolation Following the retrieval of oocytes, the first step is to identify and isolate the oocytes or embryos. This is a critical process that ensures only viable cells are selected for culturing.
  • Step 2: Placement in Culture Medium Once isolated, the oocytes or embryos are placed in a specialized culture medium. This medium is designed to provide the necessary nutrients and environment to maintain the viability and functionality of the cells during the incubation period.
  • Step 3: Incubation The oocytes or embryos are then incubated under carefully controlled conditions. This incubation lasts for one to three days, during which the development of the embryos is closely monitored.
  • Step 4: Maturation of Oocytes If the oocytes are not fully mature at the time of retrieval, they are allowed to mature in the culture medium. This step is essential to ensure that the oocytes are ready for fertilization.
  • Step 5: Fertilization For mature oocytes, a separately reportable insemination procedure is performed to fertilize the oocytes. This step is crucial for the development of embryos.
  • Step 6: Monitoring Embryo Development After fertilization, the embryos are monitored for less than four days. This monitoring is vital to assess the growth and development of the embryos before implantation.

3. Post-Procedure

Post-procedure care following the culture of oocyte(s) or embryo(s) under CPT® Code 89250 typically involves monitoring the patient for any immediate reactions or complications related to the procedure. The embryos, once cultured, are evaluated for their readiness for implantation into the uterus. The healthcare provider will discuss the next steps with the patient, which may include scheduling the implantation procedure or further assessments based on the development of the embryos. It is essential for the patient to follow any specific instructions provided by the healthcare team to ensure optimal outcomes following the procedure.
