Molly Castille MD in Baltimore: Family Practice with Hospital Affiliation and Extended Hours
Molly Castille MD operates as a primary care practice within the University of Maryland Medical Center system, serving Baltimore residents who need ongoing management of chronic disease, preventive care, and coordination with specialists. The practice accepts new adult patients and operates from a location that accommodates both scheduled appointments and same-day urgent visits.
What Castille's Practice Actually Is
Castille is a board-certified internal medicine physician providing first-line evaluation and management for conditions including hypertension, diabetes, high cholesterol, arthritis, and respiratory illness. As part of University of Maryland's network, the practice has direct electronic access to inpatient records and specialist consultations across the system, which streamlines referral and follow-up. The practice is sized for continuity; patients typically see Castille rather than rotating among multiple providers.
Services and Insurance Acceptance
The practice provides annual physicals, management of chronic conditions with medication adjustment, vaccination, basic lab work ordered in-house, and referrals to cardiology, rheumatology, and other specialties within University of Maryland or to independent providers. New-patient visits typically run 45 to 60 minutes and include health history, physical exam, and laboratory ordering where indicated; established-patient follow-ups usually take 20 to 30 minutes.
Castille accepts Medicare, Medicaid, and most major commercial insurers including CareFirst, Aetna, and UnitedHealthcare. Patients are expected to verify in-network status and copay responsibility with their insurer; typical copays for office visits run $15 to $50 depending on plan. The practice does not publish a flat fee for uninsured patients; uninsured individuals should contact the office directly to discuss payment options or eligibility for University of Maryland's financial assistance programs.
Comparing Castille to Other Baltimore Family Medicine Providers
Baltimore has several large primary care networks: Mercy Medical Center operates affiliated primary care practices in federal Hill, Canton, and other neighborhoods; Johns Hopkins Community Physicians has practices across the city; and MedStar Health operates family medicine clinics in South Baltimore and Harbor East. Castille's distinguishing factor is institutional affiliation with University of Maryland, which means electronic referrals and imaging results appear on a shared system accessible during the visit, reducing administrative delays. Mercy and Johns Hopkins practices offer similar scope but may require separate logins for specialist information. MedStar clinics often emphasize faster scheduling; wait times for new-patient appointments at University of Maryland practices, including Castille's, typically run 2 to 4 weeks during peak seasons.
Choose Castille if continuity with one physician and access to University of Maryland's specialist network are priorities. Choose a Johns Hopkins-affiliated practice if you want the option to stay within Johns Hopkins' system (e.g., if Johns Hopkins Bayview or Johns Hopkins Hospital is your preferred hospital). Choose a MedStar clinic if shortest appointment wait time is the deciding factor and you are comfortable with less appointment continuity.
Who This Practice Suits and Does Not Suit
Castille is well-suited for patients with one or more chronic conditions requiring regular monitoring, adults transitioning from pediatric care, and patients who value seeing the same provider at each visit. It is also appropriate for anyone establishing a Baltimore primary care relationship after moving to the area. The practice is not designed for same-day acute illness (that is, acute bronchitis or injury); patients with urgent but non-emergency needs should use a walk-in urgent care clinic such as GoHealth in Canton or CareFirst's urgent care locations. The practice does not offer pediatric care.
What the First Visit Involves
New patients are asked to arrive 10 to 15 minutes early to complete a paper or digital intake form covering medical history, current medications, allergies, family history, and social factors (smoking, alcohol use, exercise). The appointment itself includes vital signs taken by medical assistant or nurse, a conversation with Castille about reasons for the visit and health goals, physical examination, and discussion of any labs or imaging to be ordered. If you are establishing care for the first time in years or have multiple new symptoms, allow for a longer visit; routine physicals typically conclude within the scheduled time slot.
Bring your insurance card, a list of current medications (or bottles), and any recent lab results from a prior provider. If you have specialist letters from a previous doctor, those speed up history taking.
Hours, Location, and Parking
Castille's practice is located within University of Maryland Medical Center's outpatient plaza at 620 West Redwood Street, Baltimore, MD 21201. Office hours are Monday to Friday 8 a.m. to 5 p.m., with some evening appointments available on Tuesday and Wednesday; Saturday and Sunday appointments are not offered. Parking is available in the medical center's adjacent garage at a daily rate of $5 to $8, or validated if your appointment is with a University of Maryland provider. Street parking on Redwood Street and nearby blocks is limited and not recommended for medical appointments.
Castille's practice accepts new patients, though availability depends on the season; call 410-328-6000 (University of Maryland main line) and ask to speak with the scheduling desk for internal medicine, or check online at umms.org for appointment availability. Lead time for new-patient appointments typically ranges from 2 to 4 weeks.
Molly Castille MD fits Baltimore's primary care landscape as a continuity-focused practice with institutional resources and system integration, most valuable for patients managing multiple conditions or seeking a stable long-term physician relationship.
