Skip to content Credex Healthcare provides ASC billing services for ambulatory surgery centers seeking accurate facility claims, faster reimbursements, and fewer rejected cases. ASC billing is not the same as hospital outpatient billing or professional billing. Each facility claim requires its charge structure, revenue codes, HCPCS and CPT codes, and payer-specific packaging rules. Our ASC billing specialists know that distinction and apply it to every claim we submit.
We manage the full ambulatory surgery center billing process, from patient eligibility verification and charge capture review through ASC claims submission, insurance follow-up, and payment reconciliation. Commercial insurers, Medicare’s ASC payment system, and Medicaid managed care programs each have different fee schedules and documentation requirements for ASC facility claims. Credex Healthcare keeps all that current for every payer in your panel.

Credex Healthcare has a special way of billing for ASCs that is based on facility claim rules instead of general outpatient billing rules. Before a claim is sent out, our ASC billing specialists compare the charge capture to the operative report, ensure that the procedure codes are correctly grouped under the ASC payment group system, verify that the implant documentation and invoice requirements are met, and compare the payer’s current ASC fee schedule. Once that review is in place, the number of denials due to missing implant bills or incorrect revenue codes decreases significantly.
Our ASC billing services in the USA cover the following:
Facility claims proceed with verified CPT codes, correct revenue codes, and complete operative documentation. Real-time claim tracking flags any stalled submission before a timely filing deadline is at risk.
We handle provider application management for your ASC facility and all contracted physicians, enrolling with commercial carriers, Medicare, and Medicaid managed care organizations, so your center bills without gaps from day one of operations.
Each denied claim is reviewed within 48 hours. Our team traces the specific rejection reason, whether it is a bundling issue, a missing implant invoice, or an authorization problem, corrects it, and resubmits supporting documentation.
Our certified coders audit operative reports for accurate CPT and HCPCS code selection, correct modifier assignment, and compliance with ASC documentation requirements before any claim leaves the queue.
We initiate and track prior authorizations for scheduled procedures, confirm coverage before the patient arrives, and maintain a central log to ensure no case is billed against an expired or missing authorization.
End-to-end RCM includes eligibility verification, charge entry, payment posting, contractual adjustment reconciliation, and monthly reporting, so your finance team always has an accurate collections report.
Credex Healthcare is an ASC billing company in the USA that monitors how Medicare’s ASC payment groups operate, how commercial payers use their own ASC fee schedules, and how facility billing and professional billing duties are split across different insurer contracts. This is important to know because building claims and medical claims have different rules and payment methods, and messing them up can cost significant revenue.
Insurance billing for ASC centers spans commercial carriers, including Aetna, Cigna, UnitedHealthcare, Anthem, Humana, and BCBS plans, along with Medicare and state Medicaid programs. Credex manages enrollment and recredentialing across all of them.
Facility claims and physician claims are separate tracks with different codes, fee schedules, and payer rules. Our team manages ASC facility billing independently from the professional side, with each claim built correctly for its own reimbursement path.
ASC centers serving orthopedics, ophthalmology, gastroenterology, pain management, ENT, and general surgery all carry different CPT code sets and bundling rules. Our ASC billing specialists work across all major surgical specialties.
For ASC management companies operating multiple facilities, we coordinate facility-level and physician-level payer enrollments across all sites through a single managed workflow with consolidated reporting.
ASC facility claims need different kinds of paperwork than physician bills. For example, operation reports, implant invoices, anesthesia records, and permission forms specific to the payer are all part of the same facility claim. Before sending them in, Credex Healthcare looks over each one.
Your ASC facility NPI, tax ID, and payer-specific facility numbers are verified and applied correctly to every claim. Physician NPIs and taxonomy codes are cross-checked for each case on the schedule.
CPT and HCPCS codes are verified against the operative report and mapped to the correct Medicare ASC payment group. Packaged services, separately payable items, and device-intensive procedure rules are applied in accordance with payer guidelines.
Modifier Assignment
Modifiers 22, 50, 51, 59, and others are assigned based on the documented surgical record. Bilateral procedure rules, multiple procedure reductions, and add-on code relationships are handled correctly for each payer.
Implant & Device Documentation
Device-intensive procedures require manufacturer invoices and pass-through billing codes. We collect, review, and attach implant documentation to claims before submission to prevent the denials this step commonly triggers.
Payer-Specific ASC Fee Schedules
Medicare, Medicaid, and commercial payers each calculate ASC reimbursement differently. We maintain current fee schedules for every payer in your contract portfolio and apply the correct payment methodology to each facility claim.
Accounts Receivable Follow-Up
Aged AR reports are worked weekly. Claims approaching the timely filing limits are escalated immediately. Underpayments are identified against the contract, and disputes are prepared with the supporting billing documentation.
It is harder to see how ASC centers lose money than to see how regular outpatient rejections occur. Differently priced package services, missing implant bills, facility vs. professional claim overlap, and incorrect payment group placements are all factors that make repayment less likely without clearly leading to denials. The outpatient surgery center billing method from Credex Healthcare is designed to find these lost profits before they become permanent losses.
End-to-end ASC insurance claims management from charge entry and operative code selection to electronic submission across commercial payers, Medicare, and Medicaid.
Our ASC billing specialists apply the correct CPT codes, revenue codes, and modifiers for each procedure type and facility claim, reducing denials that come from ASC documentation requirements errors.
Prior Authorization Management
Authorizations are obtained and tracked for every scheduled case. Expiry dates are monitored against the surgical calendar, so your facility never submits a claim for an unauthorized procedure.
Denial management for ASC claims covers bundling disputes, medical necessity appeals, and documentation corrections. Recovered claims are sent back out with the specific appeal documentation the payer requires.
Provider application management covers facility enrollment, physician credentialing, and ongoing recredentialing, so your ASC bills without interruption due to staff turnover or contract renewals.
Monthly reports show AR aging by payer, denial trends by reason code, collections by procedure category, and billing turnaround time for ASC centers, giving management the numbers to run the business.

Administrator

“We had been writing off a lot of implant-related denials because we did not have a system for attaching invoices before submission. In the first month, Credex fixed that. On the next transfer, we could see that our possessions had changed. After three months, almost no one has turned down our implant. That was enough to pay for the job.”
MD
Marsh
“I own the facility, and I also operate there, so I needed billing for both the professional and facility sides handled correctly without them overlapping. Credex manages both tracks separately, and I can see them both in the monthly report. It’s been years since the numbers were clean. Good teamwork and clear communication.”
Revenue Cycle Director

“We run four ASC locations across two states. The credentialing situation before Credex was a spreadsheet mess. They checked every link between a provider and a customer, found the registration gaps, and got rid of the pile faster than I thought they would. There is now a single data view for all four sites, and I trust the numbers I see.”
CFO

“What caught my attention during the sales call was that they understood ASC payment groups and how packaging rules work. Most billing vendors do not. Credex went through our past denials by reason code and told us exactly what problems they would fix and how they would do it. They kept their promise. Debts are being paid off faster, but staff time spent on billing problems is going down.”
Practice Manager
Dunn
“GI and endoscopy billing has specific bundling rules that trip up a lot of billers. Credex got it right from day one. There was no back-and-forth about colonoscopy bundle problems, and the same treatment codes were not denied over and over again. The time it took to get things done went down, and customers stopped calling the front desk to complain about pricing mistakes. That made a big difference in the quality of life.”
Facility Assessment
We look at how you currently capture charges, how long outstanding debts are by payer, how denials are sorted by reason code, and the terms of your payer contracts. This shows us where money is going missing and what needs to be fixed first.
Credentialing & Payer Enrollment
We make sure that working doctors and your location are signed up with all the payers on your contract list. Before new cases are sent in, any gaps in provider application management are filled.
Authorization Management Setup
We get a list of all live prior authorizations, match them up with your surgery plan, and set up a proactive renewal process to make sure that no case is done without a valid authorization on file.
Clean Claim Submission
Our ASC billing experts review every operation report, make sure the CPT codes, revenue codes, and modifiers are correct, add any necessary implant paperwork, and send facility claims online to all payers.
Denial Management & Follow-Up
As a claim moves through the process, it is tracked. Within 48 hours of a rejection, a specific fix and request is made for that reason, not just a general resubmission.
Reporting & Ongoing Optimization
The monthly reports for your ASC cover facility-level receipts, rejection trends, AR aging, contract variance analysis, and time-to-bill. Problems that don't go away are reported and fixed in the next payment period.
When it comes to billing, ASC facilities are distinct from physician, hospital outpatient, and general medical billing. It is important to know how to use revenue codes, ASC payment groups, device-intensive process policies, and packed service rules correctly. Credex Healthcare specializes in ASC medical bills because other companies don’t see the differences, which means you get less money back.
Our billers work on ASC facility claims. They know how Medicare's ASC payment group system calculates reimbursement, how commercial payers apply their own fee schedules, and how implant pass-through billing works. This is not adapted from a general billing workflow.
Your facility works with a dedicated ASC billing specialist who knows your payer contracts, surgical specialties, and your claims. We handle all issues with a specialist at your clinic or center, not by passing them to a general queue.
The monthly reports show the status of claims, the number of denials by payer and reason code, the amount owed, and payments by process type. The facility's actual financial situation is shown to management without having to ask for a report.
All of ASC's payment processes must follow strict HIPAA rules when dealing with patient data. There are security standards and compliance records kept on every site that handles claims for your location.
ASC’s income leaks out quietly. Packaged treatments billed separately, implant bills missing when they are sent in, lack of permission for high-cost cases, and underpayments that match the return but not the contract are some of the problems that cost your facility real money every month but don’t always show up as rejections.
Credex Healthcare starts by giving you a free review of your current billing process, including how long your accounts receivable are, the types of payers you use, and how you record charges. You don’t have to make a promise to get that rating. We show you the gaps and how much it would cost to fix them. You then decide whether to move forward.
ASC billing services manage facility-level revenue cycles for ambulatory surgery centers, covering charge capture, CPT and HCPCS code selection, claim submission to payers, denial follow-up, and payment posting. ASC facility billing is distinct from professional billing because it uses a different fee schedule, different code sets, and different bundling rules. Without billing specialists who understand those differences, ASCs consistently leave charges uncollected due to packaging errors, missing implant documentation, and incorrect payment group assignments.
Yes. Most commercial health plans, Medicare Part B, and Medicaid cover procedures performed at Medicare-certified or accredited ASC facilities. Medicare reimburses ASC facility claims through the ASC payment system using procedure-specific payment groups. Commercial payers use their own contracted ASC fee schedules, which vary by carrier and plan. Coverage for specific procedures depends on the payer’s approved facility services list and the patient’s plan benefits. Credex Healthcare verifies benefits and ASC coverage for each patient before the case is scheduled.
ASC facility claims use CPT and HCPCS Level II codes to identify procedures performed, along with revenue code 0490 or procedure-specific revenue codes, depending on the payer. Unlike professional claims, ASC facility claims do not use evaluation and management codes. Key modifiers include modifier 50 for bilateral procedures, 51 for multiple procedures, 59 for distinct procedural services, and 22 for increased procedural complexity. Device-intensive procedures have their own HCPCS pass-through codes. Each payer applies its bundling and packaging rules to determine which codes are separately reimbursable.
Medicare processes clean electronic ASC facility claims in 14 to 30 days. Commercial payers typically pay within 30 days when documentation is complete, and codes are correct. Medicaid timelines depend on the state and managed care organization and generally range from 30 to 60 days. Implant-related claims and device-intensive cases take longer when invoices are not attached at submission, which is one of the most common avoidable delays in ASC billing. Credex Healthcare’s pre-submission review process addresses that before claims leave the queue.
