ASC Facility Billing Services
Built for ambulatory surgery centers. Facility-fee coding under the Medicare ASC Payment System, device C-codes, packaging and multiple-procedure logic, and modifier discipline (50, RT, LT, 73, 74, 59) on every claim. Clean submission through Waystar, Trizetto, and eClinicalWorks. The CY 2026 ASC payment update is +2.6%, and the Inpatient-Only list is being eliminated over three years, moving more cases into your ASC.
Trained ambulatory & EMS billers, inside your software
Coding and RCM specialists under HIPAA-compliant workflows.
ASC Facility Billing outsourcing from Staffingly covers ambulatory surgery center billing services, ASC facility billing, and ASC revenue cycle management: a HIPAA-compliant healthcare BPO model with dedicated, remote specialists (named to your account, never a shared offshore pool) who run this part of your back office as a fully outsourced team, billed at a flat weekly fee per specialist, not a percentage of collections.
Three things quietly drain ASC reimbursement
Surgery centers run on thin facility margins. Three problems show up in almost every ASC we review, and the 2026 rules make each one heavier.
Packaging and device costs billed wrong
Under the ASC Payment System, many ancillary items are packaged into the procedure payment, while implanted devices may qualify for separate C-code reporting. Mixing those up means either a denial or money left on the table on device-intensive cases like ortho and ophthalmology.
Modifier errors flip clean claims to denials
Modifier 50 for bilateral, RT and LT for laterality, 59 for distinct procedures, and 73 or 74 for discontinued cases each change the payment. Modifier 73 (stopped before anesthesia) pays the facility 50 percent and 74 (after anesthesia) pays 100 percent. Get the pair wrong and the claim bounces.
The Inpatient-Only list is moving cases to you
CMS is eliminating the Inpatient-Only (IPO) list over a three-year transition, starting with musculoskeletal procedures in CY 2026 and a new Level 7 Musculoskeletal APC. More complex cases land in the ASC, with more payer scrutiny and more prior authorization attached.

What is an ASC facility billing service ?
An ASC facility billing service is a remote revenue cycle team that codes the facility side of every case, applies the correct CPT and payment indicator under the ASC Payment System, reports device C-codes where they apply, attaches the right modifiers, scrubs the claim, and submits clean through Waystar, Trizetto, or eClinicalWorks. Not a generic VA. A trained ASC coder who lives in surgical CPT and facility packaging every day.
High-volume ASC procedure codes we work every shift
Verified AMA CPT descriptors across the busiest ASC specialties. Facility-side coding on every case.
The ASC facility modifiers that decide payment
On a facility claim, the modifier changes the dollars. We apply the right one, every time, and never stack the pairs payers reject.
What your ASC billing team handles, day to day
Pick the facility revenue cycle queues that hurt most. Your outsourced coder absorbs them. Your in-house team focuses on the surgical schedule and the front desk.
Facility-fee CPT coding
Surgical CPT coded from the operative note across GI, ortho, pain, ophthalmology, and ENT, with the correct ASC payment indicator.
Device C-code reporting
Separate device line reporting on device-intensive cases, with implant logs reconciled to the operative record.
Modifier discipline
50, RT, LT, 59, and discontinued-procedure 73 and 74 applied correctly and never stacked in payer-rejected pairs.
Packaging and SI logic
Packaged ancillaries versus separately payable items resolved per the ASC Payment System status indicators.
Multiple-procedure logic
Multiple-procedure discounting and bundling applied so the highest-weighted procedure is sequenced and paid correctly.
Clean claim submission
Submission through Waystar, Trizetto, eClinicalWorks, or your existing clearinghouse, with NCCI edits checked before drop.
Denial management
Packaging, modifier, and medical-necessity denials worked root-cause, with appeals built around the operative note.
Reports & KPIs
Days in AR, clean claim rate, denial rate by payer, net collection rate, and case-level reimbursement variance.
ASC-trained coders, not generic VAs
Most outsourcing firms put a general medical biller on surgical claims and hope the facility logic works itself out. We do not. Our ASC coders are tested on surgical CPT, ASC packaging, device reporting, and modifier logic before they touch a live claim.
ASC-coded, not generic
AAPC-credentialed coders tested on high-volume ASC CPT, payment indicators, device C-code reporting, and modifiers 50, RT, LT, 59, 73, and 74 before placement.
2026 rule alignment
CY 2026 ASC payment update +2.6%, the three-year Inpatient-Only list phase-out, the new Level 7 Musculoskeletal APC, and CMS-0057-F prior authorization timelines all built into the daily workflow.

Frequently asked questions
What is the difference between the ASC facility fee and the professional fee?
The facility fee covers the surgery center resources: the operating suite, nursing staff, supplies, and recovery, coded with the procedure CPT under the Medicare ASC Payment System and billed on the facility claim. The professional fee is the surgeon or anesthesiologist work, billed separately. Staffingly handles the facility side.
What is the CY 2026 ASC payment update?
CMS finalized a 2.6 percent update to the ASC Payment System for CY 2026, based on a 3.3 percent market basket increase reduced by a 0.7 percentage point productivity adjustment.
How does the Inpatient-Only list elimination affect my ASC?
CMS is phasing out the Inpatient-Only list over a three-year transition. For CY 2026, CMS primarily removed musculoskeletal procedures and assigned them to ambulatory payment classifications, including a new Level 7 Musculoskeletal Procedures APC. More higher-acuity cases can be performed in the ASC, which means more coding complexity and often more prior authorization.
When do you use modifier 73 versus 74?
Modifier 73 is for a procedure discontinued before anesthesia, reimbursed at 50 percent. Modifier 74 is for a procedure discontinued after anesthesia, reimbursed at 100 percent. They apply to outpatient hospital and ASC claims, are reported on one procedure per date of service, and are not combined with modifier 50.
Do you report device C-codes on implant cases?
Yes. On device-intensive procedures, an implanted device may be reported separately with the applicable HCPCS C-code, reconciled against the implant log and operative note, following current CMS and payer policy.
How is PHI and HIPAA handled across remote coders?
HIPAA-compliant workflows with a signed BAA, role-based platform access, and audit logging. PHI never leaves the controlled environment. Coders work from biometric-secured facilities.
What is included in the 2-Week Free Pilot, BAA Signed?
Two weeks of live ASC facility billing running in parallel with your in-house team. Full reporting on days in AR, clean claim rate, denial rate, CPT and modifier accuracy, and net collection trend. No setup fee. No penalty if you cancel before day 14.
How are your ASC coders trained?
Our ASC coders are AAPC-credentialed and tested on high-volume surgical CPT, ASC payment indicators and packaging, device C-code reporting, and modifiers 50, RT, LT, 59, 73, and 74 before placement.
How is ASC facility billing different from hospital outpatient billing?
Medicare ASCs bill facility claims on the CMS-1500 with place of service 24, paid under the ASC payment system, while hospital outpatient departments bill the UB-04 under OPPS and APCs. ASCs also apply the multiple-procedure reduction: 100 percent for the highest-valued procedure and 50 percent for each additional procedure in the same session.
What is place of service 24?
Place of service 24 identifies a freestanding ambulatory surgery center on the claim. Using the correct place of service is essential for ASC facility reimbursement.
How are implants billed at an ASC?
For Medicare, most implantable devices are bundled into the ASC payment for the surgical procedure; only OPPS pass-through devices are paid separately. Capturing device documentation and confirming each payer's policy protects implant reimbursement.
