Stephen J McKenna, MD, FACS in Baltimore: Bariatric Surgery and General Surgery

Stephen J McKenna, MD, FACS, FASMBS, operates as a general and bariatric surgeon in the Baltimore area, with primary credentials in the American College of Surgeons (FACS) and the American Society for Metabolic and Bariatric Surgery (FASMBS). His focus spans both general surgical problems and weight-loss procedures, positioning him in a middle band of Baltimore's surgical landscape: larger than single-specialty bariatric clinics but narrower in scope than full-service hospital surgical departments.

What McKenna's Practice Actually Offers

McKenna's dual board certifications indicate he handles two distinct surgical categories. General surgery covers acute and chronic conditions like hernia repair, gallbladder removal, and appendicitis. Bariatric surgery—his FASMBS credential—includes gastric bypass, gastric sleeve, lap-band, and duodenal switch procedures, along with the pre- and post-operative nutritional management those patients require. The FASMBS designation signals completion of specific fellowship training and ongoing education in metabolic surgery, which matters because not all surgeons advertising weight-loss procedures have this credential.

Bariatric Services and Pricing

Bariatric surgery costs in the Baltimore region run $15,000 to $35,000 before insurance, depending on procedure type and whether the surgeon operates in a hospital or surgical center. Gastric bypass (laparoscopic) typically falls in the $22,000 to $30,000 range; sleeve gastrectomy runs $18,000 to $25,000. McKenna's specific fees require direct contact, as they vary by procedure, facility affiliation, and insurance network. Most bariatric surgeons in Baltimore accept Medicare, Aetna, BCBS, and United, though coverage rules for bariatric procedures can be strict. Many insurers require documented weight-loss attempts, a BMI above 40 (or 35 with comorbidities), and proof of nutritional counseling before approval. Some patients self-pay to avoid these gatekeepers, which shifts the decision calculus. Confirm with McKenna's office whether your insurer is in-network and whether pre-approval is required.

How McKenna Compares to Other Baltimore Bariatric Surgeons

Baltimore has several bariatric programs housed within larger hospital systems. The University of Maryland Medical Center and Johns Hopkins offer comprehensive bariatric surgery services, typically staffed by 2 to 4 fellowship-trained bariatric surgeons. These centers often integrate imaging, cardiology, sleep medicine, and psychology into a structured pre-operative workup. A private bariatric practice like McKenna's may offer more scheduling flexibility and shorter wait times for initial consultation (often 2 to 4 weeks versus 6 to 12 weeks at major academic centers), but fewer immediate referral options if complications arise. McKenna's FASMBS credential puts him at parity with hospital-based surgeons on training; the real choice hinges on whether you value integrated hospital resources or convenience and single-surgeon continuity.

General Surgery Scope

For general surgery beyond bariatrics, McKenna's laparoscopic toolkit likely includes cholecystectomy, hernia repair, and appendectomy. These procedures are routine in Baltimore and offered widely by most general surgeons. The advantage of a FACS surgeon is credential transparency: board certification through the American College of Surgeons requires ongoing education and peer review. Patients can verify this at facs.org. For general surgery alone, McKenna is neither specialized nor generic; he is a reliable option but not differentiated unless you have a specific hernia complexity or need continuity with a bariatric surgeon who can also address incidental general conditions.

Who This Practice Suits and Who It Does Not

McKenna's practice suits bariatric patients who want a dedicated bariatric surgeon (not a general surgeon dabbling in weight loss) with formal fellowship training, and who prefer outpatient or surgical-center settings over hospital bureaucracy. It also suits general surgery patients willing to see a bariatric-focused surgeon for routine cases. It does not suit patients who require inpatient hospital admission for major reconstruction, are on high-risk medication regimens, or need on-site ICU backup; those patients should use a hospital-based program. Patients without insurance or with plans that exclude bariatric surgery altogether should ask upfront whether McKenna's office offers self-pay discount plans (common in the field, typically 10 to 20 percent off standard fees if you commit to paying in full or on a set schedule).

What to Expect at the First Visit

Bariatric consultations typically last 45 to 60 minutes and include dietary history, weight-loss attempts, comorbidities (diabetes, sleep apnea, hypertension), medications, and surgical goals. McKenna will likely discuss procedure options, expected weight loss (60 to 75 percent excess weight loss over 18 months for most procedures), and risks. You should leave with a clear timeline for pre-operative testing (labs, imaging, cardiac clearance if appropriate), a letter of medical necessity for insurance, and an appointment to see a registered dietitian. If you have insurance, ask during scheduling whether pre-authorization is required; some insurers will deny claims if you proceed without approval, even if the surgeon's office filed the request.

Hours, Location, and Logistics

Verify current hours and facility location directly with McKenna's office, as surgical practices sometimes consolidate or shift between hospital-affiliated and independent surgical centers. Ask whether parking is validated and whether there are wheelchair accessible facilities if needed.

McKenna's presence in Baltimore's surgical landscape reflects a clear credential path and dual expertise. Bariatric patients seeking a dedicated, fellowship-trained surgeon with established general surgery credibility have a solid option; referrals from primary care physicians or gastroenterologists carry weight in the bariatric world and may accelerate your consultation.
