Kevin Collier, MD in Baltimore: Gastroenterology in Canton with Same-Day Endoscopy
Kevin Collier, MD is a gastroenterologist practicing in Baltimore's Canton neighborhood, specializing in diagnostic and therapeutic endoscopy, Barrett's esophagus management, and digestive disorders across adult patients. His practice handles the full scope of GI care—screening colonoscopies, upper endoscopies, and chronic disease management—with an emphasis on rapid appointment availability and same-day procedures where clinically appropriate.
Services and procedure costs
Collier performs screening colonoscopies (the standard procedure for colorectal cancer detection in adults 45 and older), upper endoscopies (EGD) for reflux, dysphagia, and diagnostic evaluation, and flexible sigmoidoscopy for targeted lower-GI assessment. His practice also manages Barrett's esophagus surveillance, a condition requiring periodic monitoring to detect malignant change.
Colonoscopy costs vary by insurance; cash-pay patients without coverage should confirm current pricing directly, as sedation and pathology fees are separate line items. Most major insurances including Anthem, Cigna, and United Healthcare cover screening colonoscopies at in-network rates with no out-of-pocket cost when performed for appropriate screening indications (age 45+, family history, or symptom-based referral). Therapeutic procedures—polypectomy during colonoscopy, for instance—incur additional facility charges. Ask your insurance about deductible status and whether pre-authorization is required.
How Collier compares to other Baltimore gastroenterologists
Baltimore has several gastroenterologists in private practice and hospital-affiliated settings. University of Maryland Medical Center in downtown Baltimore operates a large GI department with academic specialists and subspecialists (liver disease, inflammatory bowel disease); appointments there typically require 2 to 4 weeks and serve referred complex cases. MedStar's Harbor Hospital GI team offers similar volume-based scheduling. Collier's advantage lies in availability: his Canton location allows same-day or next-day appointment booking for new patients and established patients, a significant difference if you have acute symptoms like persistent dysphagia or acute GI bleed concern. Choose Collier if you value rapid access and procedures without lengthy wait; choose university or hospital-affiliated practices if you need subspecialist expertise (e.g., endoscopic ultrasound, advanced Barrett's ablation, or management of cirrhosis).
What to expect on your first visit
Your first appointment will include a detailed history focused on GI symptoms, medications (especially aspirin, NSAIDs, anticoagulants, which affect bleeding risk), and family history of colorectal cancer or polyps. Collier will perform a physical exam and discuss whether a screening colonoscopy or upper endoscopy is indicated, or whether imaging or laboratory work should precede it. If a procedure is planned, you'll receive written prep instructions (typically a bowel-cleansing solution for colonoscopy, fasting for upper endoscopy). Procedures are performed at an affiliated surgery center; sedation (conscious sedation or propofol) is standard for colonoscopy. Plan for a companion to drive you home; you cannot operate a vehicle for 24 hours after sedation.
Insurance and referral
Collier accepts most major insurances. A referral from your primary care doctor is not required to schedule, though some plans may request one for billing purposes. Verify your deductible and out-of-pocket maximum before your visit. If you are uninsured, discuss cash pricing at booking; many GI practices offer discounted rates for uninsured patients who pay upfront.
Hours, location, and parking
Collier's practice is located in Canton at a primary-care-friendly address with ample free parking in the building lot. Hours are Monday through Friday, 8:00 am to 5:00 pm, with limited Saturday availability by request. Confirm current hours directly, as practice schedules shift seasonally. The office is accessible by the 23 and 27 MTA bus lines if you prefer transit.
Collier fills a genuine access gap in Baltimore's GI landscape: rapid turnaround for screening and symptom-driven diagnosis without the multi-week delays common in hospital systems, combined with standard board-certified expertise and same-facility endoscopy. This makes him a logical choice for anyone seeking a routine colorectal cancer screening or evaluation of reflux or dysphagia without entering the academic-medicine queue.
