Darryn Potosky, MD, AGAF in Baltimore: Board-Certified Gastroenterologist with AGAF Credentials
Darryn Potosky is a board-certified gastroenterologist in Baltimore whose credentials include certification by the American Board of Internal Medicine and membership in the American Gastroenterological Association Foundation (AGAF), a distinction that reflects advanced training and commitment to the field. His practice focuses on diagnostic and therapeutic endoscopy, management of inflammatory bowel disease, and general gastroenterology, serving patients across Baltimore's medical landscape who need specialty evaluation and ongoing digestive care.
What This Practice Actually Is
Potosky operates as a solo gastroenterology practice, meaning he does not belong to a larger health system and manages his patient volume and scheduling independently. This structure offers continuity: patients typically see the same provider across multiple visits, which is valuable for complex conditions like Crohn's disease or chronic pancreatitis where treatment decisions build on prior conversations. The AGAF membership is not routine among gastroenterologists; it requires adherence to educational standards and ethics guidelines beyond board certification alone, and it signals deeper involvement in the field's advancement.
Services and Diagnostic Scope
Potosky's practice encompasses the standard range of gastroenterology specialties. He performs upper endoscopy (EGD) for evaluation of reflux, dysphagia, and upper GI bleeding, and colonoscopy for colorectal cancer screening, surveillance, and diagnosis of lower GI conditions. He manages chronic liver disease, peptic ulcer disease, and pancreatic disorders. Consultation for inflammatory bowel disease (Crohn's disease and ulcerative colitis) is a noted area of focus.
Pricing for endoscopic procedures in Baltimore typically falls into bands determined by insurance plans and facility fees. A screening colonoscopy covered by insurance may carry a copay of $0 to $500 depending on the plan; diagnostic colonoscopy (with findings or biopsies) falls into a higher reimbursement category and may result in out-of-pocket costs of $200 to $1,000. Office consultation for new-patient evaluation ranges from $150 to $400, again depending on insurance. Confirm current fee information and whether Potosky's practice has a financial coordinator before scheduling.
How Potosky Compares Locally
Baltimore has several board-certified gastroenterologists in private practice and through affiliated systems including University of Maryland Medical Center and Johns Hopkins Medicine. Potosky's solo practice structure differs notably from system-affiliated peers, who often have access to in-house laboratory, imaging, and hospitalization. A system-based gastroenterologist can arrange an urgent CT or admit a patient with acute pancreatitis without coordination delay. Potosky's practice likely uses outside imaging and hospital arrangements, which can introduce scheduling friction in urgent situations but also means no pressure to drive procedures or referrals within a narrow network.
For routine screening and stable chronic GI disease, Potosky's continuity of care and AGAF standing make him comparable to or preferable to high-volume group practices where patients may see rotating providers. For complex cases requiring rapid hospital admission, advanced imaging, or multidisciplinary tumor boards, a Johns Hopkins or University of Maryland gastroenterologist is more efficient. Patients changing insurance or relocating should ask whether Potosky accepts their new plan; solo practices are more vulnerable to network changes than system-affiliated colleagues.
Who This Practice Suits
Potosky is appropriate for patients seeking long-term, continuous care from a single gastroenterologist, particularly those managing inflammatory bowel disease, chronic liver disease, or recurrent upper GI symptoms. New patients with a personal or family history of colorectal cancer or with symptoms suggestive of celiac disease or peptic ulcer benefit from initial specialist evaluation. Patients on complex medication regimens who have had prior adverse endoscopic findings often prefer seeing the same provider for follow-up surveillance.
This practice is less ideal for patients experiencing acute GI bleeding or severe abdominal pain requiring emergency assessment; they should go to an emergency department. Patients seeking second opinions at a major cancer center or Johns Hopkins for pancreatic or esophageal cancer should consider system-affiliated specialists alongside or instead. Pediatric patients and very high-risk perioperative cases also belong in a setting with immediate surgical and ICU backup.
What the First Visit Involves
New-patient visits typically include a thorough history of GI symptoms, medication review, and assessment of risk factors for colorectal and gastric cancer. Potosky will examine the abdomen and may recommend immediate testing (fecal occult blood, H. pylori serology) or schedule endoscopy if alarm symptoms are present. Expect the appointment to last 45 minutes to an hour. Insurance verification should happen before the visit; confirm whether you need a referral from your primary care physician, as some plans require a PCP referral to specialty gastroenterology even for self-referred patients.
Hours, Parking, and Logistics
Confirm current office hours and parking location directly with the practice, as solo practitioners often adjust hours seasonally and may have limited on-site parking. Baltimore's downtown medical corridor is congested; allow extra time for finding lot or street parking. Endoscopic procedures are typically scheduled at a hospital endoscopy center or ambulatory surgery center, not in the office, and those facilities have their own parking and arrival protocols.
Darryn Potosky's AGAF credential and solo-practice model make him a distinctive choice for Baltimore patients seeking continuity in gastroenterology. His practice is most valuable for long-term, non-emergent digestive care.
