What Subspecialty Maternity Coverage Actually Costs

Medically reviewed by Sina Haeri, MD, MHSA, maternal-fetal medicine physician.

Comparing locum, employed and virtual maternal-fetal medicine coverage is harder than it looks, because the three do not bill the same way. A locum agency quotes a day. An employed physician arrives as a multi-year cost. A virtual arrangement is usually a subscription or a per-encounter fee. This page sets out the cost structure of each, the variables that move the total, and the costs that never appear in a quote.

Why these models are difficult to compare directly

A locum agency quotes a daily rate. An employed physician arrives as a salary, benefits, malpractice and recruitment cost spread over years. A virtual arrangement is usually a subscription or per-encounter fee. Three different units, and the finance office is asked to compare them on one line.

The comparison only works if you convert all three to the same denominator. For most hospitals that is cost per covered day, or cost per high-risk encounter. Pick the denominator first, then ask each vendor to quote against it rather than against their own preferred unit.

Cost structure by model

The costs that do not appear in the quote

Vacancy. The period between losing a physician and replacing one is rarely costed, and for subspecialty OB it can run long. During that window, volume leaves.

Transfers. Every high-risk patient transferred out is a delivery, a length of stay and often a NICU admission that goes elsewhere. Transfer-out volume is usually tracked clinically and rarely costed financially.

Recruitment. Search fees, sign-on, relocation and the ramp period before a new hire reaches full productivity.

Coverage gaps. What happens on the nights and weekends nobody is scheduled. Diversion, transfer, or a generalist managing outside their comfort range all carry a cost, and none of them appear on an invoice.

Designation risk. If your level-of-care designation depends on maternal-fetal medicine availability, losing that availability can put the designation at risk. In Texas, hospitals without a maternal level-of-care designation have had Medicaid maternity claims denied since September 2021, which turns a staffing gap into a reimbursement problem.

What the market looks like

Locum coverage for obstetric subspecialty work is commonly quoted in the range of several thousand dollars per day before travel, lodging and agency fees, and rates move with regional scarcity and notice period. Ouma's own materials cite a range of roughly $3,500 to $5,000 and above per day for locum coverage.

Treat any published rate as a starting point rather than a benchmark. Actual quotes vary widely by geography, by how far ahead the shift is booked, and by whether the assignment is continuous or intermittent. A rate quoted for a planned three-month block and a rate quoted for weekend gap cover two weeks out are not the same number.

Questions worth asking any coverage partner

Where a virtual model tends to fit

Virtual subspecialty coverage tends to make sense where volume is real but not full-time, where the alternative is transferring patients out, or where recruitment has already failed. It tends to make less sense where a facility needs an MFM physically present, either for procedures or because its state's designation criteria require it. That is worth asking directly rather than assuming.

Ouma provides board-certified maternal-fetal medicine coverage as a physician practice licensed in all 50 states. What that costs depends on scope and volume, which is a conversation rather than a rate card.

Frequently asked questions

How much does locum MFM coverage cost per day?

Obstetric subspecialty locum work is commonly quoted in the low-to-mid thousands of dollars per day before travel, lodging and agency fees, and Ouma's own materials cite roughly $3,500 to $5,000 and above. Treat any published figure as a starting point. Rates move with regional scarcity, how far ahead the shift is booked, and whether the assignment is continuous or intermittent.

How do you compare tele-MFM cost against an employed physician?

Convert both to the same denominator before comparing, usually cost per covered day or cost per high-risk encounter. An employed physician is a fixed multi-year cost that does not scale down at low volume; a virtual arrangement usually scales with volume or coverage scope. The comparison also has to include recruitment, vacancy and ramp costs on the employed side, which rarely appear in a salary figure.

What costs do hospitals usually leave out of the comparison?

Vacancy during a search, the revenue attached to transferred-out patients, recruitment and ramp costs, uncovered nights and weekends, and designation risk where a level-of-care designation depends on MFM availability.

Does Ouma publish pricing?

No. Cost depends on scope, coverage model and volume, so a rate card would mislead more than it helps. What we can do is build the comparison with you against your own volume and your own denominator.
