The ultrasound experts, reading your scans.

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. Across 6,400+ scans at 11 practices, MFM tele-interpretation found a potential missed diagnosis in 34.5% of scans sonographers had read as normal, cardiac anomalies most of all.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.

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.

Lighten an MFM practice's read load

Already have MFMs? We take interpretation volume off their plate so your physicians can focus on the patients in front of them, added read capacity without added headcount.

Inside an OB/GYN office

We embed as the reader behind your office's scans, so patients get imaging and expert interpretation in one place. Your OBs shed the liability and skill burden of high-level reads.

Into maternity deserts

This is what Ouma has mastered. Patients get scanned close to home, but there is often no reliable expert nearby to read the study. We are that reader.

Who bills what when the read happens remotely

This is the first question most practices ask, and it has a standard answer. An obstetric ultrasound has two billable components. The technical component covers the equipment, the sonographer and the facility. The professional component covers the physician interpretation and the written report.

When a practice performs the scan and Ouma interprets it, the practice bills the technical component and Ouma bills the professional component. The patient sees one scan. The claim reflects two pieces of work performed by two parties.

Practices that currently refer the patient elsewhere for a detailed evaluation lose both components along with the visit. Practices that keep the scan in house and send the read out keep the technical component and the patient relationship. More on what a referral costs a practice →

What to confirm

• Does your payer contract handle split billing on obstetric ultrasound the way you expect?
• Who is credentialed to bill the professional component in your state and with your payers?
• How does the interpretation reach your EHR, and how quickly?

The read behind the desert

Across roughly 100 mobile-ultrasound sites and home-birth and community-midwife practices, patients can get a scan but often have no reliable expert to interpret it.³ The nearest MFM can be a two- to four-hour drive away.

Ouma is the reader on the other end of those scans. A mother in a maternity care desert gets subspecialty-level interpretation without the drive. It's the same gap our workforce research documents: 90.3% of U.S. counties with reported preterm birth data have no practicing MFM physician,⁴ and roughly 35% are maternity care deserts.⁵

It's also why we partnered with Pulsenmore, whose FDA-authorized home-ultrasound probe lets patients perform basic scans from home under MFM supervision. The device puts the scan in the patient's hands; Ouma puts the expert behind the read.
