Ambulatory surgery centers face frequent denials from multi-procedure claims, implant billing, and payer-specific ASC rules. MedCare MSO's ASC billing services pair certified surgical coders with payer-contract checks and proactive denial management on every claim, so you get paid faster and in full.
Get a Free ASC Billing ReviewEvery advance that brings bigger cases into your ORs, spine hardware, premium lenses, spinal cord stimulators also brings implant capture, pass-through coding, and payer-specific claim rules that generalist billers can easily miss. Working with an experienced ASC billing company can recover that lost revenue and take the administrative weight of complex surgical claims off your staff.

These six problems appear in nearly every surgery center we assess. Here is how MedCare MSO fixes each one at the root.
The procedure is not included in the payer's policy or that year's Medicare ASC Covered Procedures List, and the denial is reported after the money is lost. We check every case against the current CPL, LCDs, and NCDs before surgery, so coverage issues are resolved while there's still time. This gives us time to resolve coverage issues before the case reaches the OR.
Facility claims and surgeon claims are independent submissions and have independent rules. Staff trained only on physician claims mishandle both the facility and the professional side. Our coding experts specialize in facility claims and use the right forms, places of service, and modifier processes to support correct, payable claims.
Industry analysts estimate charge-capture leakage at roughly 1–3% of net revenue. Uncaptured implants are one of the biggest causes of spine, orthopedics, and ophthalmology revenue loss. MedCare MSO reconciles the materials log against every device-intensive claim, so every implant is matched to a charge line and invoice before the claim goes out.
Medicare retired the SG requirement, yet several commercial payers still consider it for payment. This makes rejections look random. MedCare MSO maintains payer-by-payer modifier rules and applies SG and POS 24 only where each payer requires them. This eliminates a significant share of those rejections.

NCCI edits bundle services that cannot be billed separately, and multiple procedure logic reduces payment on subsequent procedures. Posting teams that cannot process this properly chase phantom payments and miss the real underpayments. MedCare MSO models both rules at posting, so legitimate reductions are recognized, and true underpayments go straight to recovery.
Payers regularly pay a lower amount than the contracted case rate, and centers that post anything that shows up miss the loss. Our team posts every payment against your actual contract terms and highlights any variance.
Our ambulatory surgical center billing services run in four stages, with clear ownership and deadlines at every step. You can outsource your entire ASC billing process to us or hand us a single process that is holding you back.
We confirm coverage and authorization before scheduling. That includes checking each case against the two 2026 CMS pre-service review programs that may apply — the ASC Prior Authorization Demonstration and the separate WISeR Model — since a center's state and service mix determine which one governs.
Our certified surgical coders review the operative report and then assign the proper CPT, HCPCS Level II, and ICD-10-CM codes. We also categorize implants and devices and match them with the invoices payers need for separate pass-through payment.
Our team checks each claim against payer-specific requirements. Our checks include the correct claim form, CMS-1500 or UB-04, modifier requirements such as SG when applicable, POS 24, NCCI edits, and multiple-procedure payment rules.
We post payments that fit your contracted reimbursement terms instead of just accepting any amount sent by the payer. In case of any difference, we highlight the underpayment for recovery. We go one step further to trace the root cause of any denied claim through our denial management services .
Our certified surgical coders turn operative documentation into clean and defensible claims. Here is what it means:
We code from the operative report instead of the superbill to know the full story behind the claim. If the documentation is unclear or incomplete, our coders send the surgeon a query and wait for an explanation before the claim is built.
Each CPT code carries a payment indicator and it decides whether the code pays separately or folds into the primary procedure. We confirm the status of every code before submission and calculate the payment you should expect.
For each payer type, we apply modifiers 59, LT, and RT according to its guidelines. When a commercial payer requests modifier 51, we use it, because Medicare automatically adjusts payments for multiple procedures.
Device-intensive procedures need two things before a payer will release separate payment. The claim must carry the correct C-codes with an attached invoice. We handle both conditions for any device-intensive procedure. Before the claim leaves our office, we run a final review against the payer's requirements.

Request a ConsultationEven a good coding team can still lose money on technically sound claims. A correct CPT code can still be denied if the diagnosis doesn't meet the payer's coverage policy. Similar quiet failures cost your center more than the more evident ones.
We have built our ambulatory surgical center billing services to catch such errors before they cost you anything. Problems get fixed in scrubbing, where they cost minutes, instead of surfacing as denials, where they cost weeks.
| Element | What it does | What do we do with it |
|---|---|---|
| CPT | Identifies the surgical procedure on the facility claim | We track annual updates and check every code against the current Covered Procedures List |
| HCPCS C and L codes | Bill implants, devices, and pass-through items separately | We capture every device charge and attach the invoice documentation payers demand |
| ICD-10-CM | Establishes medical necessity against LCD and NCD policy | We match the diagnosis to the coverage policy before the claim goes out |
| CMS-1500 (837P) | Carries Medicare ASC facility claims under Part B, POS 24 | We submit Medicare claims on the right form with POS 24 applied |
| UB-04 (837I) | The institutional form many commercial payers require | We handle revenue codes and form fields that physician-side billers have never touched |
Each specialty runs its own kind of caseload, so our ambulatory surgical center billing services are staffed by coders trained for that specific work.
Multispecialty ASCs run many procedure types under one roof, each with its own payer rules, fee schedules, and authorization requirements.
GI and endoscopy centers run high claim volumes where the screening-versus-diagnostic coding distinction decides payment. our gastroenterology billing services team handles both.
The orthopedics and spine specialty carry the heaviest implant and device billing, so every screw, rod, and cage has to be captured and matched to an invoice.
Cataract centers handle high same-day volumes, IOL pricing, and premium-lens patient charges that must be billed separately from the covered procedure.
Epidural steroid injections and spinal cord stimulator implants need more authorizations than almost any other ASC service, including WISeR Model review in participating states.
ENT, urology, OB/GYN, and other single-specialty centers, including out-of-network billing strategy where payer contracts are thin.
Billing is one process of a revenue cycle starting at the operating room and ending at a rightfully contracted payment. MedCare MSO follows the whole process.
HealUs is the EHR that captures surgical notes for claims and works seamlessly with our medical billing services.
Salus provides us with the surgery note at the time of the surgery; hence, our coders work with the full note. Explore the AI scribe.
With the help of artificial intelligence, Sophus suggests possible codes, and certified coders have to approve the suggestions before sending a claim. See AI coding.
Maximus brings scheduling, eligibility, and claims together in one practice management system, or we work inside the system you already own.
All the components described above are available as a full set or a separate piece of software. Either way, your ambulatory surgical center billing services follow the same process from the operating room to a correctly contracted payment.
As an ASC billing company, we provide services that stay aligned with billing and security regulations. We also account for separate workers' compensation billing requirements. MedCare MSO maintains SOC 2 Type II–assessed security controls.
Our team tracks every annual OPPS/ASC final rule, CMS payment update, ASC coding change, and Covered Procedures List revision. In CY 2026, CMS added 289 procedures to the ASC Covered Procedures List and raised ASC payment rates by 2.6%, effective January 1, 2026. CMS also began a three-year phase-out of the hospital Inpatient Only (IPO) List, which means more surgical procedures can move to the ASC setting over the coming years.
We also support ASCQR reporting, apply NCCI edits during claim scrubbing, and maintain documentation for payer and regulatory reviews. When it comes to physician-owned ASCs, we pay attention to the Stark Law, Anti-Kickback Law, and False Claims Act so as to minimize the risk of errors in reimbursement payments.

ASC billing covers the facility fee a surgery center earns for a procedure: the OR, nursing, supplies, implants, and recovery. It is separate from the surgeon's professional fee and follows its own CMS payment system, Covered Procedures List, claim forms, and modifiers. A specialized ASC billing company handles that facility side apart from the physician claim.
ASC Billing services encompass the complete billing process for ambulatory surgery centers, including coding, submitting claims electronically, posting payments, and properly managing denied or unpaid claims. Proper ASC billing contributes to fewer claim denials, better cash flow, and compliance with both CMS and payer regulations.
SG is the modifier for ASC facility services. Medicare decided not to require this modifier on claims for ASC facility services that took effect from January 1, 2008, and onward, but certain insurers still expect it to be there as it is related to ASC payment policy.
A case rate is a negotiated payment that takes care of all expenses incurred during the course of treatment, regardless of all its aspects. This is widespread in several commercial arrangements that involve ASC billing and allows for a whole new approach in filing and processing claims.
Commonly cited industry pricing generally ranges between 3 and 7 percent of collections. It can also be based on setup fees, varying by case volume, specialty mix, payer mix, and the scope of services included.
Yes! Medcare MSO can efficiently integrate with the majority of EHR (Electronic Health Record) and PMS (Practice Management Systems) systems used by ambulatory surgery centers, enabling them to maintain a seamless workflow and an efficient revenue cycle.
