Stephen D. Humm, MD in Baltimore: A Gastroenterologist in Inner Harbor East
Stephen D. Humm, MD is a solo gastroenterology practice in Baltimore's Inner Harbor East neighborhood, offering diagnostic and therapeutic endoscopy, colonoscopy, and outpatient management of digestive disorders. He operates in an urban practice setting where volume is steady, new-patient waits typically run three to six weeks, and the patient base skews toward adult residents of central Baltimore seeking continuity rather than hospital-based referral patterns.
What the practice actually is
Humm runs a straightforward medical gastroenterology office without a surgical focus. His scope includes routine screening colonoscopies, upper-endoscopy for reflux and dysphagia workup, Barrett's esophagus surveillance, and general management of ulcer disease, irritable bowel syndrome, and functional dyspepsia. The practice does not handle inflammatory bowel disease referrals (those go to academic centers), does not perform advanced endoscopic therapy, and does not specialize in hepatology. For a Baltimore resident or primary-care physician seeking a reliable local gastroenterologist for standard outpatient scope and follow-up, this is an appropriate entry point; for complex inflammatory or surgical pathology, it is not the destination.
Services and typical costs
Screening colonoscopy with sedation (propofol by a nurse anesthetist) runs approximately $2,000 to $2,800 out of pocket before insurance; with commercial insurance, copays and coinsurance typically land between $200 and $500. An EGD (upper endoscopy) costs roughly $1,500 to $2,000 before insurance, with similar copay ranges. Office visits for established patients without a procedure are $150 to $250; new-patient consultations $250 to $350. Humm accepts most major health plans (Aetna, Cigna, United, CareFirst Blue Cross). Uninsured patients often pay a discounted rate of 30 to 40 percent below the standard charge. Prices fluctuate annually; verify with the office before scheduling.
How Humm compares to Baltimore's other gastroenterologists
Baltimore hosts at least two major hospital-based gastroenterology groups (University of Maryland Medical Center's division and Johns Hopkins), plus 15 to 20 independent or small-group practitioners spread across the city. The hospital groups offer more urgent access, complex procedural options, and integrated imaging, but require referral and higher administrative friction. Humm's advantage is speed to an initial appointment if you don't need imaging coordination, continuity with the same physician, and simpler billing for straightforward cases. Choose Humm if you have a routine screening or workup and want to avoid a hospital bureaucracy; choose Johns Hopkins or University of Maryland if you are symptomatic with possible inflammatory disease or require EUS (endoscopic ultrasound) or advanced therapeutics. Independent practitioners in Canton, Federal Hill, or Towson offer similar logistical simplicity but no obvious clinical difference for basic work.
Who this practice suits and does not suit
Humm suits middle-aged and older Baltimore residents with a primary-care physician already in place, a straightforward indication (screening, reflux management, dyspepsia), and commercial insurance or funds for self-pay. He suits patients who value seeing the same doctor repeatedly and not rotating through a large system. He does not suit uninsured or Medicaid patients needing routine access; the practice does not accept Medicaid and discounted self-pay is offered but not advertised as a program. He does not suit patients with active inflammatory bowel disease, suspected pancreatobiliary pathology, or those needing inpatient endoscopy. He also does not suit patients seeking same-day or next-week colonoscopy; plan for a three-to-six-week lead time for screening, longer if a complex issue requires consultation first.
What the first visit involves
A new patient checks in 15 minutes early and completes a standard medical history and symptom questionnaire on paper. Humm or a physician assistant takes a focused history, performs a brief abdominal exam, and reviews whether a procedure is indicated or whether office-based management (medication, dietary advice, follow-up testing) is appropriate. If colonoscopy or EGD is planned, he schedules it at a separate session (an ambulatory endoscopy center in the Harbor East building or a nearby facility) with printed prep instructions and sedation consent forms. The office visit itself lasts 20 to 30 minutes; assume 45 minutes from check-in to departure.
Hours, parking, and logistics
Humm's office is located at 701 East Pratt Street, Suite 300 (Inner Harbor East, near the National Aquarium). Hours are Monday through Friday, 8:30 AM to 4:30 PM; closed weekends and major holidays. There is metered street parking on Pratt Street and a nearby garage; the office does not operate a lot, so allow 10 minutes for parking. Public transit via MTA light rail (Harbor East stop, two blocks east) is an option. The practice is a ten-minute drive from downtown Baltimore and 20 minutes from North Baltimore suburbs. Call 410-539-3300 to schedule; most staff are present 8:30 AM to 4 PM for appointment inquiries.
Humm fills a solid, unglamorous niche in Baltimore gastroenterology: he is competent, accessible by phone, and responsive to diagnostic and management needs that don't require hospital infrastructure. For patients tired of health system wait times and automated scheduling, his practice is worth adding to the list.
