7.6 Anatomy Scan (18–22 Weeks): A Critical Milestone in Every Surrogacy Journey

The anatomy scan—also called the 20-week scan or Level II ultrasound—is a required medical milestone in every pregnancy. But in a surrogacy journey, it becomes even more crucial. At GSHC, we guide every surrogate mother and family through this key step to protect the baby’s health, maintain timely decision-making, and fulfill all contractual responsibilities.

1. What Is an Anatomy Scan?

This is a detailed ultrasound that takes place about halfway through the pregnancy. It gives the OB a clear picture of how the baby is developing. During the scan, the technician checks the baby’s brain, heart, spine, stomach, kidneys, arms, legs, face, and more. It also includes measurements, amniotic fluid levels, and placenta location. If the intended parents want to know the baby’s sex, it can usually be seen at this stage too.

The scan typically takes between 30 and 60 minutes and must be done at a facility that performs Level II ultrasounds. It’s painless, non-invasive, and very informative.

2. When Should a Surrogate Mother Get the Anatomy Scan?

The anatomy scan should be completed between 18 and 22 weeks of pregnancy:

• Best time: 18–20 weeks
• Absolute deadline: 22 weeks + 6 days

At GSHC, we emphasize early scheduling. Many ultrasound clinics won’t perform this scan after 22w6d, and last-minute appointments may be hard to find. This timeline is especially important in surrogacy, ****where delays can limit medical or legal options if complications are discovered.

3. Why the Anatomy Scan Is Essential in Surrogacy

While this scan is important in any pregnancy, it plays a special role in surrogacy. It gives intended parents a detailed update about their baby’s development and helps make sure everything is progressing as expected. If something unusual is found, it gives the medical team and the family time to follow up, speak with specialists, and make informed decisions—all before the 24-week mark when some medical options may no longer be available.

We’ve seen how timely anatomy scans give everyone peace of mind and ensure nothing important gets missed.

4. How to Request and Schedule the Scan

Here’s what you, as a surrogate, should do:

• At your OB appointment between 16 and 18 weeks, ask for the referral:

“Can I get the order for my 20-week anatomy scan?”

• As soon as you get the order, schedule your scan at an imaging center that offers Level II ultrasounds.
• Share the appointment details with your GSHC case manager so we can track everything and update the intended parents.

5. What to Request and Send after the Scan

1. Ask for a copy of the report before you leave

Most clinics will provide a printed or digital version upon request.

2. Get the OB’s final notes

The doctor—not the tech—must review and interpret the results. Ask for this written summary as soon as it’s available.

3. Send both reports to your GSHC coordinator right away

This is required for medical tracking, timely updates for the intended parents and ensuring there are no delays in compensation.

6. Critical Reminders for Every Surrogacy Journey

• Complete the anatomy scan before 22w6d
• Share all results with GSHC and the intended parents within 1 business day
• Communicate early and often if you need help scheduling

Delaying this scan can affect payment timelines, medical readiness, and emotional peace of mind for the entire team.
