Best ASC Billing Companies in 2026: 7 Top Picks 

Key Takeaways 

• Surgery centers do not charge the surgeon’s professional fee along with the facility fee. Both tracks must be clear for the center to get paid on time. 

• Medicare reimburses ASC cases using its own payment system. The procedure that pays the most is paid in full, and each additional procedure in a case with more than one procedure is paid at 50%. 

• Procedures that use many devices or implants need more paperwork than is normally included in a doctor’s billing workflow. 

• The right ASC billing company cuts down on days in arrears, finds gaps in prior authorization before bills are sent out, and takes care of payer-specific rules for place of service 24. 

Hospital outpatient departments have higher profit margins than ambulatory surgery centers, and billing mistakes on cases with more than one procedure cost a lot of money. Any modifier error, missing operating note, or prior authorization gap can cause a clean treatment to be denied. ASC billing companies that understand how surgery centers get paid handle these issues from the start, not after a rejection. 

Credex Healthcare offers ASC billing services and full medical billing services for surgery centers. These services include coding, charge capture, rejection management, and help with payment contracts. In 2026, here is how the best companies stack up. 

Why Billing Matters for Ambulatory Surgery Centers 

A site fee is charged by surgery centers. The surgeon gets paid for his or her work. These are two different claims, and neither starts to move immediately when the process is over. The facility bill must show where the service took place, use the correct payment indicators from Medicare’s list of covered surgical procedures, and account for reductions when more than one procedure is performed. 

Implants and procedures that use a lot of devices add another layer. Cases that were canceled before or after anesthesia administration are controlled by modifiers 73 and 74. If you miss either one on the right case, it results in a full denial. Beyond the basic ASC billing process, prior permission, out-of-network claims, and workers’ compensation situations each have their own rules for what paperwork to send and how to submit it. 

For a full breakdown of how the Medicare ASC payment system works, including facility fee rules and CMS-1500 versus 837P requirements, see the ASC billing guidelines. 

What Makes an ASC Billing Company Great? 

Most medical billing companies serve physician practices as their primary market. The ones that surgery centers should hire can tell the difference between a facility claim and a professional one without the center having to explain it. 

A strong ASC billing partner: 

• Handles certified medical coding for surgical fields, which includes reviewing operative notes and applying modifiers to cases with more than one treatment. 

• Manages accurate charge entry directly from the operation note, so nursing staff don’t have to enter charges manually. 

• Handles denials proactively, focusing on common medical billing denials that show up on ASC claims over and over, such as missing prior authorizations and incorrectly applied payment indicators. 

• Understands payer contracts and points out terms that make it harder to get paid for common procedures. 

• Be transparent about the scope and costs. Before you sign, find out what extra costs come with hiring a billing company. 

Best ASC Billing Companies in 2026 

Credex Healthcare (Top Choice) 

Credex Healthcare handles ASC billing in a way tailored to surgery centers. One billing coordinator is in charge of their team, which is responsible for facility fee billing, applying multi-procedure modifiers, capturing charges from operative notes, and managing denials. For surgery centers that also need surgical facility credentialing, Credex has the same team handle billing and credentialing. This takes the job of coordination off the business office manager. The paperwork for AAAHC and Joint Commission accreditation is taken care of at the same time as the billing process. 

Services: ASC facility fee billing, CPT and ICD-10 coding, charge entry, rejection management, payer contracting support, surgical facility credentialing, and billing for multi-specialty surgery centers 

Why Credex Healthcare: Surgery-center billing depth, combined billing and credentialing option, single coordinator per account 

BillingParadise 

Larger surgery centers and health systems that need help with the whole revenue cycle and high-volume ASC billing can use BillingParadise. Their team handles charge capture, coding, claim submission, and denial management for a variety of surgical specialties. Their payer follow-up workflows are designed for multi-site groups with high case volumes. For a surgery center that handles hundreds of cases every month in orthopedic, ophthalmology, and general surgery, BillingParadise’s infrastructure cuts down on the administrative work that grows as the number of cases increases. 

Services: ASC billing, coding, denial management, revenue cycle management, payer follow-up, multi-specialty billing. 

Why BillingParadise: Built for high-volume surgery centers and health systems, multi-specialty capability, end-to-end RCM 

Transcure 

Transcure serves surgery centers that perform more than one type of surgery and want to manage the entire revenue cycle with a single vendor. On the physician billing and ambulatory surgery center sides, their platform handles charge entry, coding, claim submission, ERA posting, and denial resolution. If the same management team bills both the hospital and the practice at a surgery center, having one company handle both types of claims eliminates the reconciliation step, where a lot of money gets lost. 

Services: ASC billing, physician billing, charge capture, denial management, ERA posting, full revenue cycle management 

Why Transcure: Multi-specialty RCM for centers managing facility and professional fees together, with an integrated billing workflow 

P3 Healthcare Solutions 

P3 Healthcare Solutions specializes in managing denials and following up on accounts payable for surgery centers with many rejected or past-due claims. Their team goes through open AR, finds trends of denials related to certain payers or treatment types, and settles claims that would have sat there unworked otherwise. For a center that just switched billing systems or signed a new payer contract and is seeing a rise in days in AR, a denial resolution-focused firm like P3 can get rid of the backlog faster than a general billing company could. 

Services: Denial management, AR follow-up, payer follow-up, claim resolution, ASC billing, coding audit 

Why P3 Healthcare Solutions: Denial management and AR recovery expertise, well-suited for centers with high denial rates or aged receivables 

Integra Global Solutions 

Integra Global Solutions does both ASC billing and more general back-office outsourcing. This works well for surgery centers that want to get help with billing, coding, and administration from a single company. Their team is in charge of billing for facility fees, entering charges, and submitting claims. If needed, they can also help with prior authorization management and credentials. When a center wants to cut staff or combine several vendors into one outsourced model, the combined scope makes it easier to coordinate. 

Services: ASC billing, coding, charge entry, prior authorization, credentialing support, back-office outsourcing 

Why Integra Global Solutions: Combined billing and back-office outsourcing, useful for centers consolidating vendor relationships 

GroupOne 

GroupOne goes beyond just billing companies by offering revenue cycle consulting as well. This sets them apart from companies that only handle claims without advising on the contracts and process decisions behind them. Beyond day-to-day billing, GroupOne’s advisory layer gives ASC administrators the information they need to understand denial reasons, renegotiate underperforming client contracts, or compare their revenue cycle to other centers in the same industry. Their ASC billing service takes care of collecting charges, coding them, and sending in claims. If a center wants more than just claim handling, they can use the advising part. 

Services: ASC billing, revenue cycle consulting, charge capture, payer contract review, denial management, coding 

Why GroupOne: RCM consulting alongside billing, suited to centers that want strategic input on payer performance and contract terms 

MedKloud Billing 

MedKloud Billing helps smaller surgery centers that only do one type of surgery and need professional ASC billing but don’t want the enterprise pricing that comes with bigger RCM platforms. Their team enters charges, codes them, submits claims, and follows up on denials at a level appropriate for a single-specialty center with a steady case flow. Some eye care or orthopedic ASCs don’t need a full revenue cycle infrastructure, but they do need correct facility fee bills and regular follow-up with payers. MedKloud’s limited scope and price structure make it a good fit for these types of companies. 

Services: ASC billing, charge entry, CPT coding, denial management, payer follow-up, ERA posting 

Why MedKloud Billing: Cost-effective for single-specialty and smaller surgery centers, with a focused scope and no enterprise overhead 

Why Surgery Centers Outsource ASC Billing 

It’s because the in-house approach doesn’t work at a large scale that most surgery centers switch to ASC billing companies. A predictable mix of cases from a single specialty can be handled by one coordinator. One person can’t follow up on multiple payer denials, keep track of prior authorizations, handle workers’ compensation paperwork, and do quarterly revalidation cycles all at the same time. By outsourcing, a team handles these tasks daily. This makes claims processing go faster and reduces the number of days in AR. 

Surgery centers always give these three reasons as to why they should outsource: 

• Denial rates go up when staff members leave or when a new buyer contract changes the rules for reimbursing procedures that were previously clean. Tracking common medical billing denials by payer and procedure type catches that pattern early. 

• Failures to get prior permission on finished cases, which are expensive to fix after the fact and aren’t caught by an understaffed internal billing team. 

• AR backlogs grow when billing staff don’t have experience with a certain type of surgery, and the same coding mistakes happen over and over for similar procedures. 

For a more in-depth look at surgical specialty billing, read the guide on billing companies for plastic surgery. It explains how procedure-specific knowledge changes the way different types of surgery are billed. 

The full trade-off analysis is in the guide on outsourcing vs. keeping billing in-house. Most ASC billing companies charge a percentage of collections or a flat monthly fee. Both structures are explained in the guide on percentage-based vs. flat-fee billing pricing. 

Outsourcing also gives a surgery center access to full revenue cycle management under one contract, which is more cost-effective than building the equivalent billing, coding, and follow-up capacity internally. 

Conclusion 

Credex Healthcare is the best ASC billing company we looked at because it offers the most surgery-center billing options, the best denial management, and integrated credentialing for facilities that need both. 

FAQs 

<h3 class=”single-faqs-cls”>How much do ASC billing companies charge?</h3>  

Depending on the number of cases and payer types, most charge a flat monthly fee or a percentage of what they’re paid. For a full breakdown, see the guide on percentage-based vs. flat-fee billing. 

<h3 class=”single-faqs-cls”>How is ASC billing different from physician billing?</h3>  

The surgery center charges a facility fee, and the surgeon charges a professional fee. Medicare uses its own billing method and list of covered surgeries. This is different from the medical fee plan. See the ASC billing guidelines for the full breakdown. 

<h3 class=”single-faqs-cls”>Can a billing company handle multi-procedure cases and implants?</h3>  

It should. In a case with more than one treatment, Medicare pays the most expensive procedure in full and 50% of the costs of any other procedures. On top of that, different billing rules apply to implants and procedures that use many devices. Before you decide to work with a company, find out how they handle both. 

<h3 class=”single-faqs-cls”>Should we audit our billing before switching companies?</h3>  

Yes. A medical billing audit identifies trends in denials, missed charges, and open accounts receivable (AR) to ensure a clean handoff. If you don’t have one, the new company will inherit undocumented issues, which will take longer to fix.
