San Antonio Gastroenterology

What San Antonio Gastroenterology does

San Antonio Gastroenterology Associates (SAGA) is a private gastroenterology medical practice headquartered in San Antonio, Texas, operating as a professional limited liability company under GI Alliance, a physician-led multi-specialty platform. The practice employs 14 board-certified, fellowship-trained gastroenterologists and runs three outpatient ambulatory surgery centers under the SAGEC (San Antonio Gastroenterology Endoscopy Centers) brand, including the first endoscopic ASC established in San Antonio. SAGA delivers a comprehensive menu of adult gastroenterology services spanning diagnostic endoscopy (colonoscopy, EGD, capsule endoscopy, flexible sigmoidoscopy, esophageal and anorectal manometry), therapeutic procedures (hemorrhoid banding, argon laser therapy, sphincterotomy, esophageal dilation, PEG feeding tube placement), liver assessment via FibroScan, and chronic care and infusion management. The practice has operated for more than 30 years and holds AAAHC accreditation, CMS certification, GI Quality Improvement Consortium accreditation, and Healthcare Bluebook greenlight Featured Facility status.

SAGA's revenue model is built on professional fee billing for physician services and facility fee billing for procedures performed at the three SAGEC endoscopy centers, reimbursed through a broad network of commercial insurance plans (Aetna, BCBS, Cigna, United Healthcare, Humana, and others), Medicare/Medicaid via CMS certification, Tricare, and self-pay arrangements. Patient acquisition is generated through primary care physician referrals, insurance network participation, direct appointment scheduling via the website and phone, patient education content marketing, and earned media appearances by the physicians on local television programs. Distribution is concentrated in the South Central Texas / San Antonio metropolitan area, with no disclosed geographic expansion beyond the three San Antonio locations. The legal entity is San Antonio Gastroenterology Associates, PLLC, doing business as GI Alliance, with SAGEC functioning as a wholly-owned operating subsidiary handling endoscopy center operations.
