When should an OB practice refer to MFM? For most obstetric clinics, the OB practice MFM referral decision is a constant balancing act between keeping continuity for patients they know well and getting subspecialist input for genuinely high-risk pregnancies. Traditional referral often means sending a patient to a distant academic center, disrupting the relationship and the global OB package. Tele-MFM for clinics changes that math, making a single MFM consult or ongoing co-management feasible without the patient ever leaving your practice. This guide walks through when to refer and how telehealth reshapes the economics.
When should an OB practice refer to MFM?
Maternal-fetal medicine referral is warranted when a pregnancy carries risk that benefits from subspecialist evaluation or co-management. Common triggers, consistent with ACOG and SMFM guidance, include:
- Chronic medical conditions such as pregestational diabetes, chronic hypertension, cardiac disease, renal disease, or autoimmune disorders
- Obstetric history including prior preterm birth, recurrent pregnancy loss, prior stillbirth, or prior preeclampsia
- Current pregnancy complications like a suspected fetal anomaly, growth restriction, multiple gestation, or a placental abnormality
- Genetic concerns, abnormal screening results, or the need for detailed fetal imaging
- Maternal age, obesity, or other factors that meaningfully raise risk
For a fuller framework, see our detailed guide on when to refer to MFM. The key point is that referral is not all or nothing. Some patients need a one-time consult; others need shared, ongoing management.
What is co-management, and how does it differ from full referral?
Co-management with MFM means the OB practice and the subspecialist share responsibility for a pregnancy. The OB continues to provide routine prenatal care and typically performs the delivery, while the MFM provides targeted consultation, imaging interpretation, and guidance on the high-risk aspects of the case.
This differs from full referral, where the patient is transferred to the subspecialist for the balance of the pregnancy. Co-management preserves the patient relationship and the continuity that patients value, while still bringing subspecialist expertise to bear. For many conditions, a consult plus co-management is exactly what ACOG and SMFM describe as appropriate, and full transfer is unnecessary.
The obstacle has traditionally been access. If the nearest MFM is far away, even a single consult can be hard to arrange, and true co-management can be impractical.
How does the global OB package factor into referral decisions?
The global OB package bundles routine antepartum care, delivery, and postpartum care into a single payment to the practice that provides that care. It is a central part of OB practice economics, and it shapes referral behavior in ways that are not always obvious.
When a patient is referred out entirely, the practice may lose the continuity and the delivery that the global package represents. That creates a quiet disincentive to refer, which is clinically undesirable if it delays subspecialist input. Conversely, co-management is designed to be compatible with the OB retaining the global package, because the OB continues to provide the bulk of care and performs the delivery, while the MFM bills separately for consultation and specialized services.
Understanding this distinction matters. The goal is to make the right clinical referral without an economic penalty for doing so. Co-management, done correctly, aligns those incentives, letting the practice bring in an MFM consult while preserving continuity and the global package.
How does tele-MFM change the economics of referral?
Tele-MFM for clinics removes the biggest practical barrier to timely referral, which is distance. When subspecialist consultation is available by secure telehealth, the calculus shifts in several ways:
- Patients get an MFM consult without long-distance travel or lost time
- Co-management becomes genuinely workable, because the MFM is reachable for ongoing input
- The OB practice retains continuity and, in a co-management model, the global OB package
- Referral happens earlier, because the friction of arranging it is lower
- Rural and underserved patients gain access they would not otherwise have
In other words, tele-MFM lets a practice refer when it should, rather than only when the patient can reasonably reach a distant center. That improves care and protects the practice's role as the patient's continuous obstetric home.
What should an OB practice look for in a tele-MFM partner?
When evaluating tele-MFM for clinics, consider:
- A physician-led practice staffed by board-certified MFM subspecialists
- A collaborative model built around co-management, not patient poaching
- Services spanning consultation, detailed ultrasound interpretation, and shared management
- Clear billing boundaries that keep the OB's global package intact
- Multi-state licensing and straightforward scheduling that fits clinic workflow
A partner that respects the OB's central role and adds subspecialist depth on demand strengthens the practice rather than competing with it.
Referring at the right time, without losing your patient
The best referral decisions are made on clinical grounds, at the right moment, without the practice worrying about losing continuity or revenue. Tele-MFM makes that possible by putting subspecialist expertise within easy reach and structuring the relationship around co-management.

Frequently asked questions
When should an OB practice refer a patient to MFM?
Refer when a pregnancy carries elevated risk that benefits from subspecialist input, such as chronic maternal conditions, prior adverse obstetric outcomes, suspected fetal anomalies, growth restriction, multiple gestation, or abnormal screening, consistent with ACOG and SMFM guidance.
Does referring to MFM mean the OB loses the global OB package?
Not necessarily. In a co-management model, the OB continues routine care and performs the delivery while the MFM bills separately for consultation and specialized services, so the OB can retain the global OB package.
What is the difference between MFM consult and full referral?
A consult is a one-time or occasional subspecialist evaluation, while full referral transfers ongoing care to the MFM. Co-management sits between them, with shared responsibility that preserves the OB relationship.
How does tele-MFM change referral decisions?
Tele-MFM removes distance as a barrier, so practices can arrange consultation and co-management earlier and more easily, keeping patients close to home while still getting timely subspecialist input.
