Ambulatory Surgical Center billing · Connecticut
Get ambulatory surgical center billing services in Connecticut built around the facility fee your surgery center actually bills — the ASC's own claim under the Medicare ASC Payment System, kept separate from the surgeon's professional fee and the anesthesia charge. 247MBS has run ASC facility revenue cycles since 2005 for GI, ophthalmology, orthopedic, pain, and multi-specialty centers across Hartford, New Haven, Stamford, and Bridgeport, and every client works with a dedicated account manager, a free 360° dashboard, and HIPAA + SOC 2 Type II controls. Connecticut is a Certificate-of-Need state with a tightly regulated surgical supply, which makes clean facility billing the difference between a protected margin and a written-off case.
Connecticut controls its surgical capacity through Certificate of Need: opening or expanding an ASC requires state approval, so the market is deliberately thinner than in non-CON states and each licensed center carries more volume per site. That regulatory shape raises the stakes on every facility claim — when there are fewer centers absorbing the same commercial and Medicare Advantage demand, a run of preventable denials at any one of them is felt immediately. Three Connecticut-specific mechanics decide whether a case pays cleanly.
First, the state's HUSKY Health Medicaid program does pay an ASC facility fee, but much of the membership sits inside managed-care arrangements, each with its own prior-authorization pathway and its own reading of what belongs on the ASC-approved list. Second, Connecticut workers' compensation cases — a meaningful share of orthopedic and pain-center volume — are priced under the state's workers' comp medical fee schedule rather than the commercial rate sheet, so the same procedure carries a different facility allowable depending on payer. Third, straight Medicare Part B claims route through MAC National Government Services (Jurisdiction JK) under the ASC Payment System. Getting the CON-shaped market pressure, the HUSKY managed-care rules, and the workers' comp schedule aligned on a single facility claim is what separates a paid center from one that reworks its A/R after the fact.
| Factor | Connecticut specifics |
|---|---|
| CON status | Certificate-of-Need state — regulated, thinner ASC supply |
| Medicaid ASC facility fee | HUSKY Health pays an ASC facility rate; much flows through managed care |
| Workers' comp | Priced under the Connecticut WC medical fee schedule (heavy ortho/pain volume) |
| Out-of-network law | State balance-billing protections layered under the federal No Surprises Act |
| Medicare MAC | National Government Services, Jurisdiction JK (straight Part B / ASC PS) |
| Dominant payer mix | Strong commercial + Medicare Advantage; GI, ophthalmology, ortho, pain ASCs |
The ASC facility fee is filed on the professional claim form and adjudicated under Medicare's ASC Payment System — a separate payment engine from the hospital-outpatient side, and the single biggest thing that distinguishes surgery-center billing from hospital billing. A procedure pays a facility fee only when it sits on the current-year ASC covered-procedures list with the correct payment indicator, and packaged supplies and drugs must never be billed as if they were separately payable. The list is refreshed annually, so a case that paid last year can change indicator or fall off entirely, and a center still billing it the old way collects nothing. Device-intensive cases add a second layer where the implant value is recovered only when the invoice is attached and the device offset is applied. Codes and modifiers below appear only in this table.
| Element | How it is handled on the facility claim |
|---|---|
| Form / place of service | CMS-1500 / 837P at place of service 24 (ASC) — never UB-04 |
| Covered-procedures list | Procedure on the CMS ASC list (Addenda AA/BB), each with a payment indicator |
| Multiple procedures | Highest-weighted pays 100%; subsequent payable procedures reduced (typically 50%) |
| Device-intensive / implants | Device offset via HCPCS C-codes; implant invoice required for full payment |
| Discontinued procedures | Modifier 73 before anesthesia, 74 after induction — ASC-specific, heavily audited |
| Laterality / distinct service | Modifiers 50, RT, LT, and 59 / X{EPSU} per NCCI edits |
| Screening-to-diagnostic colonoscopy | Modifier PT on the converted case |
Most lost ASC revenue in Connecticut is preventable — it comes from authorization gaps, packaging errors, and workers' comp mispricing, not from clinical shortfalls. In a CON market where commercial and Medicare Advantage plans carry the bulk of the volume, prior authorization is the single largest cause of preventable denials: a mismatched CPT, an auth tied to the wrong site of service, or an expired approval will stop an otherwise clean facility claim before it is ever adjudicated. Layer HUSKY managed-care rules and the state workers' comp fee schedule on top, and a center without dedicated facility-billing expertise loses margin on cases it fully earned. Each leak below has a repeatable fix, and we build those checks into the workflow before a claim leaves the door.

We bill the facility fee for the full spread of Connecticut centers and staff each account to its real case mix. GI and endoscopy centers built on screening-to-diagnostic conversions; ophthalmology and cataract ASCs managing IOL device offsets; orthopedic and spine surgery centers with high-cost hardware and workers' comp exposure; pain-management ASCs; and ENT, urology, podiatry, plastic/reconstructive, multi-specialty, and physician-owned surgery centers across greater Hartford, New Haven, Stamford, Bridgeport, and the Fairfield County corridor. We handle the facility claim only — the operating surgeon's professional fee and the anesthesia claim are billed separately by those providers, and we coordinate so nothing is double-billed. A high-volume endoscopy center and a spine surgery center do not run on the same economics: one lives on screening conversions and packaging accuracy, the other on device offsets and workers' comp schedules. We build each account around its actual payer and procedure mix rather than forcing every Connecticut ASC through one generic template, and we keep physician credentialing and payer enrollment current so a paneling gap never quietly holds a facility claim.
Revenue review
A certified ASC billing specialist reviews your coding, unit counts, authorizations and aged A/R against the payers you actually bill in Connecticut — and puts a number on what your current process is leaving on the table.

Running an in-house ASC billing team in a CON market this regulated is expensive and fragile — one coder's departure can stall an entire A/R cycle. Centers outsource to us because a specialist ASC billing company holds the payment-indicator logic, device-invoice discipline, and Connecticut payer knowledge that a general billing services company rarely maintains for facility claims. As a facility-focused medical billing services company, 247MBS delivers a 99% first-pass clean-claim rate, up to 40% fewer denials, 90% of worked denials recovered, and days in A/R held under 25, backed by 98% client retention across 20+ years. Our coders are credentialed professionals, and you keep a dedicated account manager plus the free 360° dashboard for real-time visibility. When you outsource the facility claim to us, you keep full clinical control and hand off the part that leaks money. Start with the full ASC billing overview, our surgery-center prior-authorization service, and the broader Connecticut medical billing services picture.
Protect the facility margin your Connecticut surgery center works for. 247MBS handles medical billing for ambulatory surgical center facilities across Hartford, New Haven, Stamford, Bridgeport, and the Fairfield County corridor, owning the facility claim from eligibility and procedure-specific authorization through charge capture and denial recovery — while surgeons and anesthesia providers bill their own claims. In a Certificate-of-Need market where each licensed center carries heavier volume, a preventable denial hurts more, so we verify HUSKY Health managed-care rules, workers' comp pricing, and commercial and Medicare Advantage authorization before the date of service instead of reworking A/R afterward. Centers that move to us typically see up to 40% fewer denials, roughly 99% clean claims, and days in A/R held under 25. Request a revenue review and we will map the leaks first.
Yes. Connecticut's HUSKY Medicaid program reimburses an ASC facility rate, but many members are enrolled in managed care, so authorization and covered-procedure rules vary by plan — we verify each before the date of service.
CON limits how many centers can open or expand, so each licensed ASC carries more volume and preventable denials hurt more. It does not change the facility-claim mechanics, but it raises the cost of getting them wrong.
No. This is the ASC facility fee only. The operating surgeon and the anesthesia provider bill their own claims separately, and we coordinate to prevent double-billing.
National Government Services, Jurisdiction JK, for straight Medicare Part B under the ASC Payment System.
