accessUltrasound Interpretation · Maternal-Fetal Medicine
Your scans, read by maternal-fetal medicine physicians.
Obstetric ultrasound is the single imaging modality MFM physicians train longest to master. Ouma puts that expertise behind your scans, reading remotely for OB practices, MFM groups, mobile-ultrasound companies, and midwives nationwide. You get higher diagnostic quality, less liability for the referring provider, and access to reimbursement you may not be capturing today.

Medically reviewed by Sina Haeri, MD, MHSA, maternal-fetal medicine physician, on September 18, 2026. Updated September 20, 2026.
- Who reads
- Every study is read by a board-certified maternal-fetal medicine physician.
- Turnaround
- Routine reads come back within 24 business hours. STAT reads come back within two hours, at no extra charge.
- What it costs
- A flat fee per study, charged to your practice. No setup fee, no subscription, and no minimum volume. The rate sheet lists each study type.
- Who bills the patient
- You do. Ouma never bills your patient or their health plan.
- Images
- Your PACS or reporting platform, or ours. We work with ViewPoint, Astraia, Tricefy, Studycast, Sonio, and Biotics AI.
- Sonographers
- ARDMS-registered preferred. We provide the protocol and worksheet for each exam type, in line with AIUM, ACOG, SMFM, and ISUOG guidance.
- Orders
- We ask that every diagnostic study carry an order from a licensed clinician who will manage the result.
- The report
- A final report signed by the reading physician, returned to you and, where you want it, to the ordering clinician.
- Where
- Ouma is licensed to practice in all 50 states.
- Who uses it
- 107 sites as of September 2026, from community midwives and birth centers to OB/GYN practices, mobile imaging companies, IDTFs, and health systems.
Two things we bring
Quality for your patients. Revenue for your practice.
Quality
Reads that catch what others miss
The subspecialist best trained on pregnancy imaging reads every scan.
- MFM physicians spend roughly 18 months of subspecialty training focused on obstetric imaging, far beyond a radiologist's few months or an OB/GYN's one to two. For the pregnant patient, MFMs are the imaging experts.2
- The data backs it up. In a study of 6,403 scans at 11 practices, 34.5% of the fetal anomalies that MFM physicians diagnosed by tele-interpretation were on scans a sonographer had marked normal. The rate was highest for cardiac anomalies.1
- Ouma follows AIUM, SMFM, ACOG, and ISUOG standards. The read sits with the subspecialist best trained to make it, raising diagnostic quality and reducing the referring provider's liability.
Revenue
Reimbursement you can't currently capture
The scans get read by experts, and the reads stay billable to you.
- Obstetric ultrasound is reimbursed by level. A practice can only bill for the scan levels it is credentialed and equipped to perform and read. Many OB practices lack the subspecialty expertise for higher-level scans.
- Partnering with Ouma opens that revenue back up. Patients get advanced, MFM-level imaging read in-house instead of referred out, and the associated reimbursement stays with your practice.
- Quality and revenue come from the same decision. The scans get read by the experts, and the reads get billed where the care happens.
How it deploys
We adapt to how you already work
Ouma is built to slot into your existing imaging workflow rather than force a new one on you. Two places matter most.
Your reading software, or ours
Already running a PACS or reporting platform like ViewPoint or Astraia? We read natively inside your existing solution, no migration, no new logins for your team.
Don't have one, or don't want to manage it? We deploy our own cloud-based PACS, so the technology is our problem, not yours. Scans in, expert reads back.
Your sonographers, scanning at an MFM level
Ouma does not employ sonographers. Your sonographers stay your sonographers. What we add is the expertise behind them.
Our MFMs meet regularly with your scanning team, review studies, and give direct feedback. Over time your imaging gets better at the source, not just at the read.
For imaging practices
For independent and mobile ultrasound practices
You own the machine and perform the exams. We handle the part you can’t do yourself — the physician read and the signed report.
Read by an MFM physician
Every study is interpreted by a board-certified maternal-fetal medicine physician.
24 hours, or 2 for STAT
Routine reads come back within 24 business hours. STAT within two, at no extra charge.
You keep the billing
A flat fee per study to your practice. We never bill your patient or their health plan.
Your PACS, or ours
Send images and the worksheet through the system you already use, or we set you up on ours.
One thing we ask
We ask that every diagnostic study carry an order from a licensed clinician who will manage the result.
That isn't red tape. If a scan shows a miscarriage, an ectopic pregnancy, or a major anomaly, the patient needs a clinician on the ground who can act on it that day — not a trip to the nearest emergency room. If you don't yet have an ordering clinician, put that relationship in place first. What has to be in place for a diagnostic scan.
sites read with Ouma today
Community midwives attending home births, freestanding birth centers, OB/GYN practices, mobile imaging companies, IDTFs, and large health systems — from a handful of studies a week to several hundred a month.
For midwifery
For midwives and birth centers
A midwifery practice or freestanding birth center runs into the same wall from two directions.
Someone qualified to read the scan
Your clients get dating, growth, anatomy, and BPP studies. Somebody has to interpret them at a subspecialist level, and sign the report.
An MFM physician you can reach
When a report raises a question, you need maternal-fetal medicine on the line — without sending a client hours away for an in-person consult.
Ouma does both
Reads come back signed. Questions get a physician.
The read
Our MFM physicians read dating, growth, anatomy, and BPP studies and return a signed report within 24 business hours — or within two hours when it's STAT.
The consult
When a finding needs a conversation, the same physicians see your client by video, review the images with them, and send the plan back to you — so care stays where they started.
The workflow
How a read works
Five steps, from your exam room to a final signed report. You scan and send; we read, report, and consult.
Your practice
You scan
Your sonographer performs the study to the protocol and worksheet we provide, in line with AIUM, ACOG, SMFM, and ISUOG guidance.
Your practice
You send
Images and the worksheet go through your PACS or ours.
Ouma
We read
A board-certified MFM physician interprets the study within 24 business hours, or two hours for a STAT read. Anatomy scans are read to the 76811 standard.
Ouma
You get the report
A final signed report returns to you and, where you want it, to the ordering clinician.
Ouma + you
If something needs attention
The report says so and the ordering clinician handles the next step. Where a patient needs an MFM consult, our physicians see them by video.
Billing
What a read costs, and how you bill
You keep the billing relationship. Practices that bill insurance bill the study; practices that don't — an elective studio moving into diagnostic work, say — collect from the patient directly. Either way, Ouma charges your practice a flat fee per study for the interpretation. We don't bill your patient and we don't bill their health plan.
Because the fee doesn't move with what you collect, your cost per study is known before you scan. There are no setup fees, no subscription, and no monthly minimum. Practices start with a handful of studies and grow from there, and a STAT read carries no extra charge.
Practices that send the patient out for a detailed evaluation lose the study and the visit along with it. Keeping the scan in house and sending only the read out keeps both.
What to confirm
- How you code and bill the study itself depends on your setup — confirm it with your biller before changing anything.
- Which licensed clinician orders your diagnostic studies and will manage an abnormal result?
- How the ordering clinician, reading physician, and medical director differ
- How does the interpretation reach your EHR, and how quickly?
