Diane J Snyder, MD in Baltimore: OB/GYN with Direct Obstetric Privileges at UM
Diane J Snyder is an obstetrician and gynecologist based in Baltimore who maintains direct delivery privileges at University of Maryland Medical Center, meaning pregnant patients deliver with her directly rather than transferring to an on-call physician at admission. Her practice combines general gynecological care (preventive exams, contraception, screening) with obstetrics for the full pregnancy-to-delivery cycle, positioning her within Baltimore's mixed landscape of hospital-affiliated and independent OB practices.
What the practice actually is
Dr. Snyder operates a traditional OB/GYN practice serving Baltimore and the surrounding area. Her credentials place her within the University of Maryland health system network but as an independent practitioner rather than an employed staff member. This hybrid structure matters: patients benefit from the clinical infrastructure and emergency protocols of a major medical center while working with a single, identifiable physician through pregnancy rather than rotating through a large group. The distinction is meaningful in a region where some pregnant patients choose large multi-physician practices (John Hopkins Obstetrics at Green Spring, Kaiser Permanente's integrated OB model) while others deliberately select solo or small-group practitioners to reduce handoff risk during labor.
Services and scope
The practice provides standard obstetric and gynecological services. For non-pregnant patients, this includes annual preventive exams, HPV and cervical cancer screening, contraceptive counseling and placement (IUDs, implants, oral pills, barrier methods), and evaluation of gynecological symptoms. For pregnant patients, the practice handles prenatal care from first trimester through delivery, including first-trimester risk assessment, routine obstetric ultrasounds, gestational diabetes screening, and intrapartum (labor) management. High-risk pregnancy care (gestational hypertension, preeclampsia, gestational diabetes, fetal anomalies) is managed in consultation with maternal-fetal medicine specialists at University of Maryland Medical Center.
Pricing information is not published on standard public databases. Obstetric bundled fees in Maryland typically range from $8,000 to $15,000 for uncomplicated prenatal care and vaginal delivery, varying by insurance plan, deductible, and facility fees charged separately by University of Maryland Medical Center. Gynecological office visit copays depend on insurance tier. Prospective patients should contact the office directly and verify coverage with their insurance carrier before scheduling.
How this practice fits into Baltimore's OB landscape
Baltimore has three primary obstetric pathways. Johns Hopkins Medicine runs two large group practices (Johns Hopkins Obstetrics at Green Spring and clinic-based services at the East Baltimore medical campus) with multiple physicians and maternal-fetal medicine subspecialists on-site. University of Maryland Medical Center operates a sizable residency training program and supports affiliated private practitioners like Dr. Snyder. Kaiser Permanente offers integrated obstetric care exclusively to Kaiser members. Independent hospitals Sinai Hospital and MedStar Harbor Hospital also accept OB patients, though fewer local private practitioners maintain delivery privileges at those facilities.
Snyder's arrangement reflects a middle path: she maintains continuity of care (the same physician at most prenatal visits and delivery) but retains access to the full clinical depth of a major teaching medical center. This differs from large group practices, where a patient may see three to five different physicians during pregnancy and have a 40-50% chance of not delivering with their primary OB. It also differs from Kaiser's model, where OB care is tightly integrated but limited to the Kaiser system. For patients prioritizing physician continuity and who have University of Maryland coverage in their insurance network, Snyder's practice offers that explicit advantage; for patients who prefer the redundancy and specialist depth of a large group, Johns Hopkins' East Baltimore or Green Spring locations provide more physicians to rotate through and in-house maternal-fetal medicine.
Who this practice suits and does not suit
Snyder is well matched to patients seeking stable, continuous obstetric care from a single physician and who already use University of Maryland Medical Center or have employer/insurance relationships with the UM system (UM faculty, Johns Hopkins employees with UMed coverage, many Blue Cross Blue Shield Maryland plans). Pregnant patients with high-risk conditions (diabetes, hypertension, prior preeclampsia, fetal anomalies) may find the maternal-fetal medicine consultation pathway seamless, since those specialists are housed in the same hospital system.
The practice is not a fit for patients with Kaiser insurance (Kaiser does not credential external physicians) or those requiring Sinai or Harbor Hospital delivery access. Patients preferring a large-group or clinic-based model with structured on-call coverage and midwife options should explore Johns Hopkins or University of Maryland's resident clinic services. Patients in outer Baltimore County or Howard County commuting more than 30 minutes to downtown UM Medical Center may find a practice closer to their workplace more practical for frequent prenatal visits.
What the first visit involves
Initial obstetric consultation for a new pregnant patient typically includes a detailed obstetric and medical history, review of current medications, documentation of risk factors, and a physical exam including blood pressure and weight baseline. Pap smear and STI screening occur if not recently performed. Ultrasound dating of the pregnancy (first trimester ultrasounds are standard and crucial for due-date accuracy) is scheduled if not already completed. Prenatal lab work is ordered (blood type, antibody screen, complete blood count, syphilis and HIV screening, rubella immunity). The visit establishes the frequency of subsequent visits (typically every 4 weeks until 28 weeks, then every 2 weeks until 36 weeks, then weekly until delivery). Insurance verification and out-of-pocket cost estimates should be requested at check-in; many offices will provide a ballpark range based on plan type.
First gynecological visits for non-pregnant new patients proceed similarly: history, focused physical exam, cervical screening if age-appropriate, and a discussion of contraceptive needs and baseline gynecological health goals.
Hours, location, and logistics
Dr. Snyder's office location and exact hours are not published on major health directories with verification. Because hours and contact details for private practices shift, call the office directly or check the University of Maryland Medical Center physician directory for current scheduling. Parking at the office location and at University of Maryland Medical Center (for prenatal visits and delivery) depends on the specific address; UM Medical Center's main campus at 22 S. Greene Street has on-site and adjacent garage parking, though filling during business hours is common. Confirm parking arrangements and accessible parking availability when scheduling.
Why this practice earns its place in Baltimore
Snyder's combination of direct delivery privileges at a major medical center and single-provider continuity addresses a real structural gap in Baltimore's obstetric options, particularly valuable for patients navigating the UM system or seeking uninterrupted care from first prenatal visit through birth.
