Joyce M. Koh, M.D. in Baltimore: Gastroenterology with Hepatology Expertise
Joyce M. Koh, M.D., is a gastroenterologist based in Baltimore whose practice emphasizes both routine GI care and specialized liver disease management, serving patients who need screening, treatment of reflux and inflammatory bowel conditions, and those with hepatitis or cirrhosis.
What Koh's Practice Actually Is
Koh operates as a physician gastroenterologist accepting new patients and offering both diagnostic procedures (endoscopy, colonoscopy) and medical management of gastrointestinal and hepatic conditions. The practice is embedded within Baltimore's medical landscape where gastroenterology services range from primary-care referral practices to tertiary hepatology centers at Johns Hopkins and University of Maryland. Koh's dual focus on general gastroenterology and hepatology makes her relevant for patients whose primary concern is the stomach and esophagus but who may have underlying liver disease complicating their care, or for those with known hepatitis C, hepatitis B, or cirrhosis seeking ongoing management.
Services and What to Expect Cost-Wise
The practice offers upper endoscopy (EGD), colonoscopy, and office-based management of acid reflux, irritable bowel syndrome, inflammatory bowel disease, and liver disease. Most gastroenterologists in the Baltimore area bill procedure fees through insurance; balance varies sharply based on whether your plan negotiates rates with Koh's facility network. New-patient office consultations typically run 45 to 60 minutes. For procedures, confirm with the office whether your insurance requires prior authorization before scheduling; without it, facilities may delay the procedure date. Hepatology consultation fees (if billed separately from general gastroenterology) are not standardized and depend on insurance contract terms; call the practice to ask whether your plan covers hepatology as a billable specialty or bundles it into gastroenterology reimbursement.
How Koh Compares to Other Baltimore Gastroenterologists
Baltimore offers gastroenterology across multiple tiers. Larger practices affiliated with Johns Hopkins Medicine or University of Maryland Medical Center employ multiple gastroenterologists and offer same-day or next-day appointments for urgent issues like GI bleeding; they typically have longer wait lists for routine colonoscopy screening (often 4 to 6 weeks). Smaller independent practices, including single-doctor offices, often have shorter wait times for first consultations (1 to 2 weeks) but may not have the capacity for urgent same-day procedures. Koh's dual training in hepatology is less common among general Baltimore gastroenterologists; if your concern is primarily acid reflux or IBS, any board-certified gastroenterologist will suffice, but if you have hepatitis C that was treated years ago and you want surveillance for hepatocellular carcinoma, or if you have cirrhosis and need management of portal hypertension, Koh's hepatology focus becomes a competitive advantage over colleagues whose practice emphasizes screening colonoscopy.
Who This Practice Suits and Does Not
Koh's practice is well-matched for established adult patients with chronic GI conditions (reflux, IBS, Crohn's disease) who benefit from continuity with one physician, and for patients with liver disease who want their gastroenterology and hepatology care integrated. Patients seeking a high-volume, one-stop facility for quick appointments or urgent GI bleeding may be better served by a large hospital-based practice, which can move faster in emergencies. Pediatric patients will not be served by Koh's adult practice; Baltimore gastroenterologists accepting children include providers at Johns Hopkins and University of Maryland pediatric programs.
What the First Visit Involves
New-patient appointments require insurance information and a detailed history of GI and liver symptoms. Bring records of prior imaging, endoscopy, or liver biopsy if available. Koh will conduct a focused history and physical exam, typically order baseline labs if needed (liver function tests, CBC), and discuss whether screening colonoscopy is due, whether upper endoscopy would clarify your symptoms, or whether medical therapy (a proton pump inhibitor for reflux, dietary change for IBS) is the right starting point. If you have known liver disease, expect questions about alcohol use, prior hepatitis exposure, and current medications; Koh may order ultrasound or refer for transient elastography (fibroscan) to assess fibrosis. Procedures are usually scheduled separately; the office will coordinate with an endoscopy facility.
Hours, Location, and Logistics
Verify current hours and street address with the practice directly, as these change. Parking details depend on where the office is sited; most Baltimore gastroenterology offices in hospital-affiliated buildings offer validated parking. If Koh's office is in a standalone building or smaller medical plaza, confirm parking availability before your appointment.
Koh's integration of hepatology within a gastroenterology practice fills a specific gap for Baltimore patients whose liver disease is mild enough not to warrant referral to a specialized hepatology center but complex enough to benefit from more training in that specialty than a general gastroenterologist possesses.
