Heather Johnson, MD in Baltimore: Solo OB-GYN Practice with Direct-Access Prenatal Care

Heather Johnson, MD is an independent obstetrician-gynecologist based in Baltimore who operates as a solo practitioner, meaning patients work directly with her rather than cycling through a large group. Her practice emphasizes continuity of care in obstetrics, where the same doctor oversees pregnancy and delivery, and accepts Medicare, Medicaid, and major commercial insurance plans.

What the practice actually offers

Johnson provides full-scope obstetric and gynecological services: prenatal care from conception through delivery, gynecologic surgery (hysterectomy, fibroid removal, ovarian cyst management), and routine preventive gynecology including contraception counseling, Pap testing, and menopause management. As a solo practitioner, she delivers at a specific Baltimore hospital and manages her own on-call schedule, which means her patients know their birth provider in advance rather than meeting an OB for the first time during labor. This model differs substantially from large group practices, where patients often see multiple doctors during pregnancy and may deliver with whoever is on call.

Scheduling, insurance, and access

New patients typically wait 2 to 6 weeks for an initial appointment, depending on whether the visit is urgent. Johnson's office accepts Medicare, Medicaid (including Maryland Medicaid), and major commercial insurers including CareFirst BlueCross BlueShield, Aetna, and United Healthcare; patients should confirm coverage before booking. Walk-in visits are not available; all appointments are scheduled in advance. Prenatal patients are seen monthly until 28 weeks, then every 2 weeks until 36 weeks, then weekly until delivery, which aligns with standard obstetric protocol. The practice does not offer fertility treatment or hormonal replacement therapy, referring those patients elsewhere.

How this practice compares to other Baltimore obstetric options

Baltimore's obstetric landscape includes large hospital-based groups (Johns Hopkins, UM Medical Systems, Mercy Medical Center) where patients see multiple doctors and are assigned on-call coverage at delivery; independent practices like Johnson's; and a small number of midwife-led practices that offer continuity but do not manage high-risk pregnancies independently. Large groups offer redundancy and easier coverage if your primary provider is unavailable, but many patients report seeing a different doctor at each visit. Johnson's solo practice guarantees continuity but requires the patient to trust one provider's judgment and accept her vacation schedule and hospital affiliation. Solo practices work best for low-risk pregnancies where continuity matters more than organizational backup; large groups suit patients who want multiple perspectives or are managing complex medical conditions. Midwife practices are another continuity option but typically require physician backup for labor complications.

Whom this practice suits and does not suit

Johnson's practice works well for patients seeking one consistent OB throughout pregnancy and delivery, especially those with uncomplicated pregnancies, prior vaginal deliveries, or comfort with a straightforward relationship. It does not suit patients requiring maternal-fetal medicine subspecialty care (multiple pregnancy, severe preeclampsia, fetal anomaly), those needing frequent provider changes due to complex medical history, or those who prefer the organizational scale of a hospital system. Patients who anticipate needing same-day care should verify the practice's cancellation policy and call-back time.

The first prenatal visit

An initial appointment typically runs 60 to 90 minutes and includes a detailed obstetric and medical history, a full physical exam, blood work (type and screen, complete metabolic panel, infectious disease screening), urinalysis, and often a first ultrasound to confirm dates and rule out multiple pregnancy. Johnson reviews medications, surgical history, and family history before scheduling subsequent visits. Patients should bring insurance cards and a photo ID.

Location, hours, and parking

The practice is located in central Baltimore. Office hours are generally Monday through Friday, 8:30 a.m. to 4:30 p.m.; verify current hours and holiday closures by phone. Parking availability varies by location; call ahead if you are unfamiliar with the building. Deliveries occur at the hospital where Johnson has privileges; she will specify that hospital during your first visit.

Solo OB practices are less common in Baltimore's consolidated medical landscape, making Johnson's direct-access model a meaningful option for patients who prioritize seeing the same doctor throughout pregnancy and birth.
