Official Description

Preparation of embryo for transfer (any method)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 89255 refers to the preparation of embryos for transfer, utilizing any method deemed appropriate. This procedure is a critical step in assisted reproductive technology, particularly in in vitro fertilization (IVF) processes. During this preparation, embryologists meticulously assess the quality of embryos, which are typically evaluated on either day three or day five of development. The goal is to identify the healthiest embryos that have the highest potential for successful implantation and pregnancy. Once the optimal embryos are selected, they are placed in a small volume of fluid, which serves as a medium for transfer. This fluid, containing the selected embryos, is then loaded into a catheter. The subsequent step involves a separate procedure where the catheter is inserted through the cervix and into the uterus, allowing for the precise placement of the embryos in the upper uterine cavity. This careful and methodical approach is essential for maximizing the chances of a successful pregnancy following embryo transfer.

1. Indications

The procedure associated with CPT® Code 89255 is indicated for the following:

  • Assisted Reproductive Technology This procedure is performed as part of in vitro fertilization (IVF) cycles to facilitate the transfer of embryos into the uterus.
  • Embryo Selection It is indicated when there is a need to select the healthiest embryos for transfer, which is crucial for improving the chances of successful implantation and pregnancy.
  • Infertility Treatment The procedure is indicated for patients undergoing treatment for infertility, where embryo transfer is a necessary step in achieving conception.

2. Procedure

The procedure for CPT® Code 89255 involves several critical steps to ensure the successful preparation of embryos for transfer:

  • Step 1: Embryo Assessment The embryologist begins by examining the embryos that have been cultured in the laboratory. This assessment typically occurs on day three or day five of embryo development. The embryologist evaluates the morphology and development of each embryo to determine which ones exhibit the best characteristics for transfer.
  • Step 2: Selection of Healthy Embryos After the assessment, the embryologist selects two to four of the healthiest embryos based on established criteria for viability. This selection process is crucial as it directly impacts the likelihood of successful implantation and pregnancy.
  • Step 3: Preparation of Embryos for Transfer The selected embryos are then placed in a small amount of fluid, which serves as a transport medium. This fluid is essential for maintaining the viability of the embryos during the transfer process.
  • Step 4: Loading the Catheter The fluid containing the selected embryos is carefully loaded into a catheter. This catheter is designed to facilitate the transfer of the embryos into the uterus with precision.
  • Step 5: Catheter Insertion A separate procedure is performed to insert the catheter through the cervix and into the uterus. This step is critical as it ensures that the embryos are placed in the optimal location within the uterine cavity for potential implantation.
  • Step 6: Release of Embryos Once the catheter is properly positioned in the upper part of the uterus, the embryos and fluid are released from the catheter. This careful placement is essential for maximizing the chances of a successful pregnancy.

3. Post-Procedure

After the embryo transfer procedure associated with CPT® Code 89255, patients may be advised to rest for a short period. It is common for healthcare providers to recommend monitoring for any signs of discomfort or complications. Patients are typically instructed to follow up with their healthcare provider for further evaluation and to discuss the next steps in their fertility treatment plan. The expected recovery time is generally brief, but individual experiences may vary. It is important for patients to adhere to any specific post-procedure instructions provided by their healthcare team to optimize the chances of a successful outcome.
