Facility billing · Ambulatory surgery centers
An ASC claim looks like an ordinary outpatient claim and behaves like nothing of the sort.
Your ambulatory surgical center billing services should collect the full facility fee on every case — and that is what 247 Medical Billing Services has delivered to single- and multi-specialty ASCs since 2005. We run the facility revenue cycle across Medicare, Medicaid, and commercial payers, give you a dedicated account manager plus a free 360° reporting dashboard, and stay HIPAA-compliant and SOC 2 Type II throughout.
Reimbursement runs on a facility-fee system assembled from packaging, payment indicators, and carve-outs — and each of those is a lever that either pays your center in full or quietly shorts it.
You bill the facility fee only — never the surgeon's work. The ASC claim covers the surgical facility's resources: the OR, nursing, recovery, routine supplies, and most drugs. The surgeon bills their own professional fee, the anesthesia provider bills anesthesia, and pathology and radiology bill independently, each on a separate claim. Put an E/M, the operative work, or the anesthesia component on the facility claim and it denies.
The claim form flips by payer. For Medicare, ASC facility services are a Part B benefit filed on the professional claim with a facility place-of-service code — the institutional form is wrong. Many commercial and Medicaid payers require the institutional form and revenue codes instead. A form-and-code mismatch auto-denies, and it is one of the most common reasons an ASC's first claim to a new payer bounces.
The covered list decides whether you get paid at all. Medicare pays an ASC facility fee only for procedures on its ambulatory surgical center covered procedures list. Bill an inpatient-only or office-only procedure in the ASC setting and there is no facility payment — no matter how clean the rest of the claim is.
Packaging hides half the revenue rules. Most supplies, drugs, and integral imaging are bundled into the facility fee and are never paid separately. Only specific separately-payable items pay on top. Billing a packaged item on its own line is a top denial and overpayment risk; missing a genuinely separate device offset leaves large money on the table.

Getting every one of those right on each case, before the claim ever leaves the center, is precisely the work professional ambulatory surgical center billing services exist to do. We work each piece of the facility fee so a case pays to its real value — nothing bundled away that should have paid, nothing billed loose that should have stayed packaged:
| Payment element | What it is | What we manage |
|---|---|---|
| Covered procedure | A surgical code that appears on the CMS ASC covered procedures list (Addenda AA/BB), verified before scheduling | Covered-list check on every code before the case, so nothing is billed that the setting won't pay |
| Payment indicator | The status code (G2 standard, J8 device-intensive, P2/P3 office-capped, R2 separately-payable radiology, N1 packaged) that tells the payer how a code pays | Indicator-correct billing so packaged items stay bundled and separately-payable items get billed |
| Device offset (J8) | The carve-out that pays an implant's device portion at the full offset amount instead of the reduced facility rate | Device HCPCS C-codes reported correctly, with the offset captured so expensive implants aren't underpaid |
| Multiple-procedure discount | Highest-paying procedure at 100%, each additional covered procedure at 50% | Correct sequencing by facility payment, and the device portion of a J8 procedure protected from the 50% cut |
| Discontinued-procedure modifier | Facility modifiers that set payment when a case is stopped — before anesthesia versus after | The anesthesia-timing trigger applied correctly, never the physician's discontinued-procedure modifier on the facility claim |
The facility fee is assembled from a short list of decisions, and a generalist tends to leave money on each one. We work all of them on every case:
Every CPT is confirmed against the current covered procedures list before scheduling and again before billing. The annual expansion of that list — and the ongoing phase-out of the inpatient-only list — means codes move on and off the payable set every year, so this is not a one-time setup, it's a running check.
Surgical supplies, most drugs, anesthesia materials, and most integral imaging are packaged into the facility fee. Radiology with a separately-payable indicator, pass-through and high-cost drugs, pass-through devices, corneal tissue, and brachytherapy sources pay on top. We bill each item to its true indicator instead of guessing.
On device-intensive procedures the implant's device portion is paid at the full offset amount, un-reduced by the facility scalar — but only when the device code is reported and, where applicable, the no-cost or partial-credit device modifier is attached. Miss the modifier on a credited device and it becomes an overpayment; miss the offset entirely and the implant is underpaid.
When several procedures happen in one session, only the top-paying one pays at 100%; the rest pay at 50%. The device portion of a device-intensive case is not reduced. Sequence it wrong and you either underbill the session or trigger a takeback.
Left unmanaged, these are the four places an ASC's facility revenue slips away one remittance at a time. Managed correctly, they are the difference between a case paid in full and a case paid in part.
Everything it takes to move an ASC claim from the operative report to paid, run by one certified team rather than split across vendors:
Operative reports translated to the correct surgical codes by our certified surgical coding team, every code checked against the current covered procedures list, and each line billed to its payment indicator so packaged items stay bundled and separately-payable items get captured.
Device HCPCS C-codes reported, the device offset captured on device-intensive cases, and no-cost or partial-credit device modifiers applied with the implant log and invoice behind them.
The correct claim form and place-of-service for each payer, multiple procedures sequenced by facility payment, scrubbed and filed within 24 hours.
Every denial worked to root cause, from covered-list and packaging rejections to device-offset shortfalls, with No Surprises Act disputes filed inside the deadline.
The center and its surgeons enrolled and re-credentialed so nothing rejects on facility or provider eligibility.
If you'd rather keep ambulatory surgical center billing and coding services under one roof, that's exactly the model — certified coders and billers on the same team, sharing the same operative record, instead of handing your claims between companies. It all runs on the same end-to-end revenue cycle management discipline, tuned to a facility fee.
An ASC lives or dies on throughput, and throughput is the enemy of careful billing. The same day your OR turns a dozen cases is the day your coder is asked to remember which supplies packaged, which implant carried an offset, which procedure led the session, and which payer needed the institutional form — and to do it fast enough not to slow the schedule.
That pressure is exactly why so many centers quietly lose facility revenue: the rules are learnable, but they are unforgiving under volume, and a single mis-sequenced session or unbundled N1 line can cost more than a day's margin.
Outsourcing the billing to a dedicated ambulatory surgical center billing services company takes that decision load off your clinical team and hands it to people who do nothing else. Your staff stays focused on turning the room; we own the covered-list checks, the payment indicators, the device offsets, and the payer-by-payer form logic. You trade a fixed internal cost — hiring, training, and re-training coders on a rulebook that changes every January — for a specialist team that already knows it cold, plus a dashboard that shows you exactly what every case collected.
Bringing us on isn't hiring a general biller who happens to accept ASC claims. It's hiring an ambulatory surgical center billing company that already knows where facility revenue leaks and how to stop it — and the numbers hold because of it.

A generalist learns ASC facility rules on your claims. We show up already fluent in them — and the difference shows up on the remittance:
Most ASC losses trace back to the same handful of failure points. We close each one at the front end, before it becomes a denial or a recoupment:
Billing a procedure not on the covered list
Full facility denial (inpatient-only or office-only in the ASC)
We verify every code against the current covered procedures list before scheduling and before billing
Unbundling packaged (N1) supplies, drugs, or integral imaging
Overpayment and unbundling takeback
We bill packaged items inside the facility fee and only line-bill genuinely separate items
Device-intensive procedure billed without the C-code or offset
Underpaid implant or missed carve-out revenue
We report the device HCPCS C-code and capture the offset on every J8 case
No-cost or credited device without the credit modifier (FB/FC)
Overpayment and a standing audit target
We apply the no-cost or partial-credit modifier with the implant log and invoice behind it
Wrong claim form or place-of-service for the payer
Auto-denial on a Medicare-vs-commercial form mismatch
We file the professional claim with POS 24 for Medicare and the payer-required form for commercial/Medicaid
Discontinued case mis-modified (73 vs 74, or physician's 53 on the facility claim)
Wrong facility payment percentage or a compliance flag
We set the facility modifier by anesthesia timing and never put the professional discontinued-procedure modifier on the facility claim
One exposure found nowhere else
ASC compliance carries one exposure found nowhere else in facility billing: the center is often owned by the surgeons who refer to and operate in it, which puts the Anti-Kickback Statute and its ASC investment safe harbor at the center of your posture.
We bill in a way that keeps the claim chain defensible — matching every CPT to the operative report, keeping the implant log and invoice for credited devices, never unbundling packaged items, never billing a code the setting doesn't authorize, and keeping Good Faith Estimate and dispute files ready for out-of-network cases.
We also flag quality-reporting gaps, because a reporting failure silently reduces every facility payment through the two-tier conversion factor. The ownership arrangement itself stays with your counsel; our job is to make sure the billing never becomes the weak link. Request a revenue review and we'll show you which of these is hitting your remits right now.

High-volume centers where covered-list checks, payment indicators, and multiple-procedure sequencing have to be right across a dozen specialties every day.
What decides the moneyGetting all three right, every day
Orthopedic, GI and endoscopy, ophthalmology, ENT, pain, urology, and plastics facilities, each with its own device-offset and packaging profile.
What decides the moneyThat specialty's own offset profile
Where the ownership disclosure, safe-harbor discipline, and charge-integrity audits matter as much as the coding, because the owners refer and perform the cases they profit from.
What decides the moneyCharge integrity alongside the coding
The newer, higher-acuity procedures migrating into the ASC as the covered list expands and the inpatient-only list phases out.
What decides the moneyA covered list that moves each year
Where the facility fee packages anesthesia resources but the anesthesia professional claim bills separately; our anesthesia billing team handles that side of the case, and our pain management billing services cover the interventional procedures that fill many ASC schedules.
What decides the moneyTwo claims that never collide
Changing billers shouldn't put a hole in your cash flow, and with us it doesn't.
We bill inside your existing practice-management and ASC systems, so nobody has to relearn a platform.
Credentialing and payer-enrollment review run in parallel while your claims keep going out the door, and a named account manager leads the transition from day one.
Most centers are fully live within a few weeks, and because there's no long-term lock-in, the results are what keep you, not the contract.
The denial drop and the faster A/R turn up in the first cycles, not a quarter down the road.
Collect the full facility fee on every case — nothing bundled away that should have paid.
And nothing billed loose that should have stayed packaged. We run the facility revenue cycle end to end: covered-list checks before the case is scheduled, indicator-correct charge capture, device offsets captured on device-intensive sessions, multiple procedures sequenced by payment, and the right claim form for each payer. Because we absorb the rule-tracking that changes every January, your clinical team stays on turning the room while the money follows the OR. Centers that move their medical billing to us typically see denials fall by up to 40%, clean claims near 99%, net collections near 99%, and days in A/R under 25 — with unbundling and overpayment risk kept off the books.
