Surgical Information Systems

What Surgical Information Systems does

Surgical Information Systems (SIS), founded in 1996 and headquartered in Alpharetta, Georgia, is a privately held healthcare technology company that provides cloud-based software and managed services purpose-built for ambulatory surgery centers (ASCs) and hospital perioperative environments. The company operates a dual business model: a SaaS platform anchored by SIS Complete, an end-to-end ASC management suite covering scheduling, clinical documentation (SIS Charts), patient engagement (SIS Exchange), surgeon engagement (SIS Link), business intelligence (SIS Insights), and compliance (SIS Comply), paired with SIS Revenue Cycle Services, a tech-enabled billing, coding, and transcription offering that processes over $2 billion in payments annually on behalf of clients. For hospitals and HOPDs, SIS provides SIS Anesthesia (AIMS), SIS Surgery (perioperative management), and SIS Analytics, all delivered on Microsoft Azure infrastructure.

The product portfolio includes both organically developed platforms and acquired brands retained from SourceMed (2017 acquisition: AdvantX, Vision, SurgiSource), Amkai (AmkaiOffice, AmkaiCharts), and more recent additions Surgical Notes (November 2024 acquisition) and ASC Logs (2025 acquisition). The technology strategy emphasizes interoperability, with 150+ integrations spanning hospital EHRs (MEDITECH, Epic, Cerner, eClinicalWorks), clearinghouses (Waystar), BI platforms (Qlik, SAP BusinessObjects), drug databases (FDB), and medical device systems (Qualcomm/Capsule). SIS Comply is HITRUST-certified and HIPAA-compliant. In June 2026 the company introduced SIS Scribe, an AI-powered transcription tool that converts physician dictation into operative notes to accelerate documentation and revenue cycle start.

SIS serves over 2,900 ASCs and hospitals across the United States with more than 90,000 physician users. The company sells predominantly through direct enterprise field sales supplemented by inside sales and an event-driven demand-generation engine focused on ASCA and state-level ASC conferences. Revenue is generated through recurring software subscriptions (annual billing, custom pricing per ASC), managed RCM services priced as a percentage of collections or per-transaction packages, and compliance platform subscriptions. Pricing is not publicly disclosed; deals are quote-based following personalized demos and ROI consultation. The company has historically held the #1 ASC EHR ranking from Black Book Research for 11 consecutive years (through 2026) and has won Best in KLAS for ASC Solutions multiple times, including 2026. SIS is backed by Norwest Equity Partners (2010) and Accel-KKR (2020), and current CEO Tim O'Brien (appointed June 2026, previously CEO of Finvi and a senior leader at athenahealth) leads the company alongside President of SIS Software Douglas Rempfer and President of Revenue Cycle Services John Lynch.

Recent moves6 records

Expansion highlights6 records

Direct peers

• HST Pathways: Direct competitor offering cloud-based practice management, EHR, and RCM solutions purpose-built for ambulatory surgery centers. Highly comparable product scope, target customer (ASCs), and SaaS-plus-services model.

Broad incumbents

• NextGen Healthcare: Established ambulatory EHR and practice management vendor with ASC and specialty practice modules. Comparable in ambulatory EHR and RCM functionality, though broader across specialties beyond surgery.
• eClinicalWorks: Major ambulatory EHR vendor with scheduling, documentation, and patient engagement tools used by ASC-adjacent practices. Comparable in ambulatory clinical documentation and patient engagement, but not ASC-specialized.
• Epic Systems: Dominant hospital EHR vendor actively expanding ambulatory and surgical scheduling capabilities. SIS interoperates with Epic today but Epic's enterprise bundling is the principal competitive threat in the hospital segment.
• MEDITECH: Hospital EHR vendor in SIS's MEDITECH Alliance Program; competes with SIS Anesthesia and SIS Surgery for perioperative IT budget in MEDITECH-installed hospitals. Closely comparable in AIMS integration and perioperative workflows.
• Oracle Health (Cerner): Enterprise EHR and perioperative software competitor following Oracle's acquisition of Cerner. Comparable in hospital perioperative and anesthesia IT, with strong ability to bundle against SIS via enterprise contracts.
• R1 RCM: Large-scale, tech-enabled RCM services provider serving hospitals and large physician groups. Directly comparable as a tech-enabled RCM services competitor, particularly for ambulatory and surgical volumes flowing through SIS today.
• athenahealth: Cloud-based EHR, practice management, and patient engagement vendor; SIS's new CEO Tim O'Brien held senior roles there. Comparable ambulatory SaaS platform and an indirect talent/strategy reference point rather than a direct ASC competitor.

Others

• Waystar: Healthcare payments and RCM clearinghouse that serves as both SIS's technology partner (insurance verification, claim status) and a potential competitor in adjacent revenue cycle workflows. Highly comparable in payer connectivity and RCM infrastructure.

Emerging players

• Phreesia: Patient intake, engagement, and payments platform expanding into specialty and surgical workflows. Comparable in patient engagement (overlap with SIS Exchange) and pre-operative intake workflows for ASCs.
