Dr. Misoul Constantine in Baltimore: Internal Medicine with Extended Hospital Hours
Dr. Misoul Constantine is an internist in Baltimore who practices internal medicine with an emphasis on hospital-based care coordination and chronic disease management. The practice operates at Mercy Medical Center on Russell Street in West Baltimore, making Constantine accessible to patients who work or live near the hospital campus and who need coordination between office visits and inpatient episodes.
What Dr. Constantine actually is
Constantine holds an MD degree and practices internal medicine, the broad specialty that manages common diseases in adults, from hypertension and diabetes to heart disease and infection. Unlike cardiologists or endocrinologists who focus on a single organ or system, internists address the whole patient and refer to specialists when needed. Constantine's affiliation with Mercy Medical Center means he rounds on inpatients in the hospital as well as seeing office patients, a model less common in private practices but standard at many academic and teaching hospitals.
Services, insurance, and new-patient status
Constantine accepts new patients for office visits focused on preventive care, management of chronic conditions, and follow-up after hospital discharge. The practice is located at Mercy Medical Center, which is part of the Bon Secours Mercy Health system. Office visits are typically 20 to 30 minutes for established patients and may run longer for new patients during the first appointment.
Insurance acceptance depends on the payer's contract with Mercy Medical Center; Medicare, Medicaid, and most Blue Cross Blue Shield plans cover visits at Mercy, but coverage varies. Call Mercy Medical Center's scheduling line at the main hospital number to verify your specific plan before booking.
The practice does not hold walk-in hours; all appointments are scheduled in advance. Lead time for a first visit typically ranges from two to six weeks depending on the season and the doctor's schedule.
How Constantine compares to other Baltimore internists
Baltimore's supply of internists divides between private practices (often independent groups or small multispecialty offices), health system affiliations (Johns Hopkins, University of Maryland Medical Center, Mercy), and federally qualified health centers serving low-income populations. Private practice internists in neighborhoods like Canton or Federal Hill may offer same-day or next-day appointments for acute problems but typically coordinate inpatient care indirectly through the hospitalist team. Mercy-affiliated internists like Constantine manage their own hospital patients, reducing handoff errors and allowing the physician to follow a patient from admission to discharge without delegation to another doctor.
Hospital-based internists suit patients with frequent hospital admissions, complex medical histories, or who prefer continuity of care across settings. Private practice may feel less hospital-heavy for patients whose care is routine office-based and who rarely need hospitalization. The choice is less about quality and more about your care pattern.
Who suits this practice and who does not
Constantine's practice works well for patients with multiple chronic conditions (heart failure, COPD, kidney disease, diabetes) who benefit from close tracking and hospital coordination. Patients who live or work near Mercy's West Baltimore location and who can reach appointments during standard office hours also have an advantage. Those needing rapid same-day care for acute problems, or who live in East or South Baltimore far from Mercy, may find a closer private practice or an urgent-care center more practical for immediate issues.
What the first visit involves
New patients should bring a photo ID, insurance card, and a list of current medications, supplements, and any recent lab results or imaging. The visit includes a full history, physical examination, and review of preventive care (vaccination status, cancer screening, cardiovascular risk). Constantine may order baseline labs (CBC, metabolic panel, lipid panel) depending on age and symptoms. The appointment typically lasts 45 minutes to an hour.
Hours, parking, and logistics
Office hours are Monday through Friday, 8:00 a.m. to 5:00 p.m., with no weekend or evening availability. Mercy Medical Center offers on-site parking in a multi-level garage on Russell Street; parking is free for outpatient visits (verify current policy when scheduling). The office is located in the main hospital building, accessible by public transit (MTA bus lines serve Russell Street) and by car. Street parking is available but often limited during business hours.
Dr. Constantine's affiliation with Mercy Medical Center and willingness to manage patients across both office and hospital settings make him a practical choice for Baltimore residents with complex medical needs or frequent hospitalizations in West Baltimore.
