Samuel Kallus, MD in Baltimore: Colorectal Specialist in Harbor East
Samuel Kallus, MD operates Capital Digestive Care, a single-physician gastroenterology practice located in the Harbor East neighborhood, serving Baltimore with a focus on colorectal conditions and procedures including colonoscopy, sigmoidoscopy, and hemorrhoid treatment.
What Capital Digestive Care actually is
Capital Digestive Care is a private gastroenterology practice run solely by Dr. Kallus. Unlike multispecialty medical centers or hospital-affiliated clinics, this is an independent office-based practice, meaning procedures occur in an accredited outpatient facility rather than a hospital. The practice specializes in colorectal diagnosis and treatment, though it also manages general digestive complaints. For patients accustomed to large systems, this model means a single doctor manages continuity of care and builds familiarity across visits.
Services and procedure pricing
The practice performs colonoscopies, flexible sigmoidoscopies, and office-based hemorrhoid treatments (rubber banding and injection sclerotherapy). Colonoscopy screening costs vary by insurance; patients with Medicare or commercial plans typically pay copays between $200 and $400 out-of-pocket after insurance processes the claim. Self-pay patients without insurance should call to confirm current rates, as facility fees fluctuate. Hemorrhoid procedures run $300 to $600 depending on the method and whether the visit is diagnostic or therapeutic. The practice accepts most major insurance plans; call ahead to verify your specific carrier and plan tier. Confirm current pricing before your appointment, as facility and anesthesia fees adjust periodically.
How it compares to other Baltimore gastroenterologists
Baltimore has several gastroenterology options across different settings. Hospital-affiliated practices like those at Johns Hopkins and University of Maryland Medical Center often have longer wait times (4 to 8 weeks) for routine colonoscopy but may be preferable if you need hospital-based care or have complex medical needs. Larger multispecialty groups such as Chesapeake Gastroenterology offer more provider choice and same-day cancellation slots but less personal continuity. Capital Digestive Care's single-provider model suits patients who value seeing the same physician consistently and can accept 1 to 3 week wait times for routine screening; it is less practical if you require specialist subspecialties like hepatology or inflammatory bowel disease management beyond basic referral.
Who this practice serves and who it doesn't
Capital Digestive Care is best for patients seeking routine colorectal screening, hemorrhoid management, and general gastroenterology care who prefer a stable doctor-patient relationship. Its Harbor East location is accessible to central and east Baltimore residents. The practice works well for patients with straightforward insurance or those willing to navigate self-pay arrangements. It is not the right fit for patients who need hepatology, advanced inflammatory bowel disease care (beyond initial evaluation), or interventional endoscopy (like stent placement or complex foreign-body removal), as Dr. Kallus does not perform those procedures. Patients requiring second opinions on complex cases may be better served by academic medical centers.
What the first visit involves
New patients should plan 60 to 90 minutes for the appointment. The visit begins with registration, insurance verification, and a detailed history covering digestive symptoms, family history of colorectal cancer, and prior screening results. Dr. Kallus then conducts a focused abdominal and digital rectal exam. If a colonoscopy is scheduled for the same or next visit, you will receive a prep kit (typically a gallon of polyethylene glycol solution or a bisacodyl/magnesium citrate combination) with detailed instructions on timing and diet restrictions the day before. Ask at intake whether your insurance requires a referral from your primary care doctor; most do not, but some plans do. Bring a photo ID, insurance card, and a list of current medications and supplements.
Hours, location, and parking
Capital Digestive Care operates in Harbor East near the waterfront, in an accessible office building with dedicated parking or nearby street parking. Standard hours are typically 8:30 a.m. to 5:00 p.m. Monday through Friday; verify exact hours by phone, as occasional schedule adjustments occur. The office is easily reached by car from I-83 and the Harbor Tunnel Thruway and is near public transit on the Charm City Circulator Orange Line. Call 410-539-0933 to confirm current hours or arrange an appointment.
Samuel Kallus's independent practice fills a gap for Baltimore patients who want streamlined colorectal care without hospital bureaucracy and value knowing their physician by name.
