Ambulatory surgery centers · Updated 2026-08-31
The best ambulatory surgery center software in 2026
An ambulatory surgery center runs on tight turnover between cases, and the software has to keep up: a missing pre-op clearance or an unresolved authorization cancels a slot nobody can easily refill. Facility billing has to stay separate from the surgeon’s professional fee, and CMS’s ASC Quality Reporting Program adds data the system has to capture along the way, not bolt on later. We compared the platforms ASCs actually run on, from full clinical suites to billing-first tools. No paid placements — just the real market, with indicative pricing.
The picks at a glance
| Software | Best for | Indicative pricing |
|---|
| HST Pathways | Multi-specialty and orthopedic ASCs that want scheduling, clinical and financial data in one system | from ~$500/month (single user), scaling with staff count — quote-based above entry tier |
| Surgical Information Systems (SIS Complete) | ASCs that want built-in revenue cycle services alongside the clinical software | quote-based |
| AdvancedMD | Independent ASCs that want to start with core modules and add clinical/financial pieces over time | quote-based, modular (cost rises as you add modules) |
| ModMed (gGastro ASC) | Gastroenterology-focused ASCs that want a specialty-built system, not a generalist EHR | quote-based |

The contenders, in detail
1. HST Pathways
Pricing : from ~$500/month (single user), scaling with staff count — quote-based above entry tier
Multi-specialty and orthopedic ASCs that want scheduling, clinical and financial data in one system
HST Pathways is a cloud platform built specifically for ambulatory surgery centers, connecting OR scheduling, clinical documentation, inventory and billing in one system across the full case lifecycle. It is the dominant PMS among multi-specialty and orthopedic ASCs and ships with 230+ built-in reports.
Strengths
- +Deep case-lifecycle coverage: scheduling, charting, inventory and billing connected end to end
- +230+ built-in reports give visibility without exporting to a BI tool
- +The dominant platform for multi-specialty and orthopedic centers, so peer references are easy to find
Watch out for
- −Implementation for larger centers runs into the tens of thousands of dollars and 6-12 months
- −Per-user pricing means cost climbs fast as the center adds staff
2. Surgical Information Systems (SIS Complete)
Pricing : quote-based
ASCs that want built-in revenue cycle services alongside the clinical software
SIS Complete is an ASC-specific platform covering case coordination, clinical documentation, billing and revenue cycle services in one system, backed by dedicated ASC billing services. It won 2026 Best in KLAS for ambulatory surgery center solutions — its fourth win in five years — and serves over 2,700 surgery centers.
Strengths
- +2026 Best in KLAS winner for ASC solutions — a strong independent satisfaction signal
- +Revenue cycle and billing services bundled in, not just software
- +Serves 2,700+ centers — a mature, well-referenced vendor
Watch out for
- −No published pricing — budget only firms up after a quote
- −Reporting leans on pre-built reports, with less raw-data access than HST Pathways for teams that want custom analytics
3. AdvancedMD
Pricing : quote-based, modular (cost rises as you add modules)
Independent ASCs that want to start with core modules and add clinical/financial pieces over time
AdvancedMD is a cloud EHR and practice management platform hosted on AWS, offering configurable surgical-encounter templates and modular pricing for independent ASCs that want clinical and administrative tools together. It also serves physician practices broadly, so ASC-specific depth sits alongside a wider general platform.
Strengths
- +Modular structure lets a center start narrow and expand
- +AWS-hosted cloud platform with configurable templates by procedure type
- +Broader physician-practice ecosystem if the ASC is tied to affiliated clinics
Watch out for
- −Total cost of ownership can climb quickly once several modules are added
- −Less ASC-specific out of the box than HST Pathways or SIS — more configuration to fit surgical workflows
4. ModMed (gGastro ASC)
Pricing : quote-based
Gastroenterology-focused ASCs that want a specialty-built system, not a generalist EHR
ModMed’s gGastro is a gastroenterology-specific EHR and ASC platform that separates facility billing from professional-fee billing, auto-suggests codes from clinical documentation, and pulls the data ASCs need for CMS quality reporting. It is built around one specialty rather than general multi-specialty surgery.
Strengths
- +Purpose-built for GI ASC workflows — pre-op, intra-op and post-op documentation with fewer clicks
- +Facility billing kept separate from professional fees, reducing a common denial source
- +Captures data toward CMS ASCQR reporting requirements as part of routine documentation
Watch out for
- −Narrow specialty focus — a poor fit for multi-specialty or orthopedic centers
- −Pricing requires a sales conversation; no published rate
5. CollaborateMD
Pricing : from ~$235/month (Starter); Basic, Growth and higher tiers are quote-based
ASCs that want to fix billing and claims without replacing their clinical system
CollaborateMD is a cloud practice-management and billing platform with real-time claim submission, eligibility checks and a built-in clearinghouse, and it publishes resources specifically on ASC revenue cycle management. It is billing-first rather than a full clinical EHR.
Strengths
- +Lowest published entry price in this comparison
- +Real-time eligibility checks and a built-in clearinghouse reduce claim rework
- +Can sit alongside an existing clinical/EHR system rather than replacing it
Watch out for
- −Not a clinical documentation or OR-scheduling system — billing and practice management only
- −Higher tiers move to custom quotes, so the real cost at ASC scale needs a sales call

How to choose
01OR scheduling that prevents cancellations, not just books time
Most preventable cancellations trace back to incomplete history, missing pre-op clearance or an unresolved authorization. Check whether the scheduling workflow flags these gaps before the day of surgery, not after the patient has arrived.
02Facility billing kept separate from professional fees
An ASC bills the facility fee while the surgeon bills separately — mixing the two, or a mismatch between the authorized and the submitted procedure, is one of the most common denial triggers. Confirm the software treats this as two distinct billing tracks, not one workflow force-fit for both.
03Built-in support for ASCQR reporting
CMS’s ASC Quality Reporting Program requirements keep expanding, and missing them affects payment. Look for a system that captures the required data points during routine documentation rather than a separate reporting exercise your staff has to remember.
04Total cost, implementation included
Subscription price is only part of the bill: implementation for a full clinical suite can run from a few thousand dollars for a small center to tens of thousands for a larger one, over months. Weigh that against a billing-first tool that layers onto a clinical system you already have.
Frequently asked questions
How much does ambulatory surgery center software actually cost?
It depends heavily on scope. HST Pathways reportedly starts near $500/month for a single user and scales with staff count — roughly $1,500/month for 10 users, $5,000/month for 100. CollaborateMD’s billing-focused Starter plan begins around $235/month with higher tiers quote-based. SIS Complete, AdvancedMD and ModMed’s gGastro are quote-based across the board. On top of the subscription, implementation for a full clinical suite commonly runs $5,000-10,000 for a small center and can exceed $50,000 for a larger one — get that number in writing before comparing subscription prices alone.
Do I need a full clinical suite, or would a billing-focused tool cover what I actually need?
If your clinical documentation and OR scheduling already work and the pain is claims and revenue cycle, a billing-first platform like CollaborateMD can fix that without replacing what already works. If scheduling, charting and billing all need to move to one connected system, HST Pathways and SIS Complete are built for that full scope — and gGastro if the center is gastroenterology-only.
Does this software help with CMS ASC Quality Reporting Program (ASCQR) requirements?
The ASC-specific platforms here are built to capture ASCQR-relevant data as part of routine clinical documentation rather than as a separate task — HST Pathways, SIS Complete and ModMed’s gGastro all position this as a core capability. Confirm during the demo exactly which measures are captured automatically versus which still need manual entry, since ASCQR requirements have expanded in recent years.
