Browser Agents That Operate SIS Charts & SIS Complete

The Problem

Why ASCs on SIS Charts Need AI

SIS gives you the system of record — clinical documentation, anesthesia, scheduling, billing. AI agents fill the labor gap around it.

94%

Of physicians report prior authorization delays affect patient care, per AMA 2024 Prior Authorization Survey.

65%

Of US healthcare claim denials are never appealed due to staffing constraints — even though 82% of appealed denials get overturned (CAQH 2024).

11%

Average ASC staff turnover for billing and front-desk roles in 2024, per MGMA — straining call coverage.

38%

Of inbound ASC patient calls go to voicemail outside business hours, per ASCA 2024 — calls Flexbone covers 24/7.

Implementation

Live in Four Weeks Alongside SIS Charts

Forward-deployed engineers configure Flexbone to your ASC's specific SIS workflows, payer mix, and surgical specialties.

Week 1 — Discovery

We map your SIS Charts case workflows, anesthesia documentation patterns, payer mix, call volumes, and current PA/eligibility/denial load. Read-only SIS Complete credentials provisioned.

Week 2 — Build & Integration

Voice agents trained on your ASC's call scripts. Browser agents configured against SIS Charts and SIS Complete. Phone system integration and SIS writeback logic go live.

Week 3 — Supervised Go-Live

Real patient calls and real PA submissions run through Flexbone and into SIS, monitored by your team. Edge cases escalate to humans during the ramp.

Week 4 — Optimization

We tune routing accuracy, refine specialty-specific call flows, and verify every SIS writeback — clinical, scheduling, and billing. Forward-deployed engineers stay engaged post-launch.

Use Cases

Built for Multi-Specialty SIS ASCs

SIS powers hundreds of multi-specialty surgery centers. Flexbone AI agents are configured per specialty, with SIS Charts writebacks tuned to each.

Orthopedic ASCs on SIS

Pre-op clearances, hardware vendor coordination, post-op PT referrals. AI calls confirm imaging, medical clearances, and DME orders before each case — logged straight into SIS Charts.

Ophthalmology ASCs

High-volume cataract days. AI handles eligibility verification at scale across the SIS case board, post-op drop instructions, and follow-up scheduling — without overloading staff.

GI & Endoscopy

Bowel prep instructions, NPO confirmation, anesthesia/sedation history review pulled from SIS Charts. AI handles the pre-op call workload that scales with screening volume.

Pain Management

Repeat injection scheduling, prior auth on every interventional procedure, opioid screening, and post-procedure check-ins — all handled by AI and posted into SIS.

Plastic & Cosmetic

Self-pay pricing conversations, deposit collection, custom pre-op imaging coordination, and discreet post-op outreach — managed at scale and synced back to SIS Complete billing.

ENT & Multi-Specialty

Specialty-specific call flows in a single deployment on top of SIS. AI agents route by surgeon, procedure, and payer logic — no separate system per specialty.

HIPAA Compliant

AES-256 at rest, TLS 1.3 in transit. PHI never leaves your compliance boundary.

SOC 2 Type II

Independently audited. BAA signed before any production data flows.

Full Audit Trail

Every AI action logged with transcript, timestamp, and SIS Charts writeback record.

Human-in-the-Loop

Configurable escalation rules. Your staff stays in control of every edge case.

FAQ

Frequently Asked Questions

Surgical Information Systems (SIS), which operates under the SISfirst brand, is one of the dominant EHR and practice management platforms for ambulatory surgery centers in the US. Its SIS Charts and SIS Complete products serve hundreds of multi-specialty ASCs and earned 2026 Best in KLAS for ASC — the company's fourth KLAS win in five years — and #1 Black Book ASC software for 11 consecutive years. SIS is known for deep clinical documentation, anesthesia records, and ASC-specific billing.

Yes. Flexbone deploys voice agents and browser agents that work alongside SIS Charts, SIS Complete, and the broader SISfirst product suite. Voice agents handle inbound and outbound patient calls. Browser agents log into SIS the way your staff does — submitting prior authorizations, verifying eligibility through payer portals, retrieving case and anesthesia schedules, and writing structured updates back into SIS — without requiring a custom API.

Yes. Flexbone is HIPAA compliant with SOC 2 Type II controls, AES-256 encryption at rest, TLS 1.3 in transit, role-based access control, and complete audit trails for every AI action. Patient data never leaves your compliance boundary, and a BAA is signed before any production data flows.

Four weeks from contract to first production calls. Week 1 is discovery — mapping your SIS Charts workflows, payer mix, and call patterns. Week 2 is build and integration against SIS Complete. Week 3 is supervised go-live. Week 4 is optimization with our forward-deployed engineers tuning the system to your ASC's specialties and edge cases.

Yes. Flexbone's browser and voice agents run the full prior authorization workflow for surgical procedures — submitting requests through payer portals, calling payers when portals fail, tracking status across the case lifecycle, and writing approvals back into SIS. This eliminates the 13+ hours per week ASC staff typically spend on PA work, per AMA 2024.

Flexbone is not a replacement for SIS or HST Pathways — it is an AI labor layer that sits alongside whichever EHR you already run. SIS remains your system of record for clinical documentation, anesthesia records, scheduling, and billing. Flexbone's voice and browser agents handle the phone calls, prior authorizations, eligibility checks, and denial follow-ups that would otherwise require more front-desk and billing staff. Nothing about your SIS deployment changes.
