A surgeon may offer the same outpatient procedure at two different locations: a freestanding surgery center and a hospital outpatient department. The appointment may look similar from the patient’s perspective. The insurance claims—and sometimes the patient’s share of the bill—can be quite different.
Those differences matter to the people scheduling procedures, the clinicians deciding where care is safest, and the billing teams responsible for getting the claim right. In 2026, Medicare also expanded the range of procedures that can qualify for outpatient payment. That change creates more options, but it does not make every procedure suitable for every setting.
Quick answer: An ambulatory surgical center (ASC) is a separately certified outpatient surgical facility that Medicare generally pays under the ASC payment system. A hospital outpatient department (HOPD) operates as part of a hospital and is generally paid under Medicare’s Hospital Outpatient Prospective Payment System (OPPS). For professional claims, ASC services commonly use place of service (POS) 24; on-campus and off-campus HOPDs generally use POS 22 and 19, respectively. Actual coverage and payment depend on the procedure, patient, facility, payer, and date of service. See CMS place-of-service definitions.

What Is an Ambulatory Surgical Center?
An ASC is a distinct facility primarily organized to furnish surgical services to people who do not need an inpatient hospital admission. Medicare-certified ASCs operate under specific Conditions for Coverage, maintain an agreement with CMS, and are designed for procedures with a limited anticipated recovery period.
CMS describes the expected duration of ASC services as no more than 24 hours after admission. That is a planning and certification standard, not a promise that a patient can never develop complications or need transfer to a hospital. Unexpected circumstances sometimes require a longer stay or escalation of care. CMS explains its ASC certification requirements here.
A center might perform cataract operations, endoscopic procedures, selected orthopedic surgeries, pain-related procedures, or other operations approved for the setting. The specific list changes and must be checked against current Medicare payment files. A procedure being common in an ASC does not establish medical necessity or guarantee that a particular insurer will pay.
Can a hospital own an ASC?
Yes. Ownership alone does not determine how a facility is billed. A hospital may own an ASC that remains separately identifiable, licensed or certified as required, and enrolled with its own Medicare supplier agreement. If it instead operates as a provider-based hospital department, different hospital outpatient requirements and payment rules apply.
A building across the street from a hospital is not automatically an ASC. Nor does an operating room inside a building branded as a “surgery center” prove that it has ASC status. Billing teams should verify the entity’s actual enrollment and certification rather than infer its status from signage or ownership.
What Is a Hospital Outpatient Department?
An HOPD is part of a hospital that provides care without a formal inpatient admission. HOPDs can perform outpatient surgery, diagnostic testing, infusion services, observation care, and other services within their capabilities and applicable requirements.
Some HOPDs sit on the hospital’s main campus. Others operate at a location away from the main hospital and qualify as off-campus provider-based departments. This distinction can affect professional-claim place-of-service reporting and Medicare facility payment.
A person can spend the night in a hospital under outpatient observation status and still not be an inpatient. Medicare status follows the admission and coverage rules, not simply the length of time spent in a hospital bed. Medicare’s inpatient-versus-outpatient explanation is useful when patients are unsure which benefits apply.
Do HOPDs always have more clinical resources?
Hospital-based departments may have easier access to hospital diagnostic services, inpatient beds, specialized staff, or emergency resources. Exactly what is available depends on the facility. A high-quality ASC also has monitoring, emergency procedures, trained personnel, and transfer arrangements. The relevant question is whether the selected site can safely manage the anticipated procedure and the patient’s individual risks—not which acronym sounds more comprehensive.
Which Procedures Can Be Performed in an ASC or HOPD?
Many familiar operations can take place in either setting, subject to clinical and payer requirements. Examples include selected cataract procedures, endoscopy, knee arthroscopy, hand surgery, and some pain interventions. The right location depends on surgical complexity, anesthesia, patient health, expected monitoring, and the resources on site.
Three separate decisions should not be confused:
- Clinical appropriateness: The treating team considers whether the patient can safely receive the service at that facility.
- Code and payment eligibility: Medicare determines whether an eligible procedure appears on the current ASC Covered Procedures List (CPL) or may be paid in a hospital outpatient setting.
- Coverage and reimbursement: The patient’s insurance, medical-necessity requirements, authorization, network status, claim rules, and applicable payment files determine whether and how payment may occur.
For example, moving a procedure from Medicare’s inpatient-only list permits outpatient hospital payment when clinically appropriate; it does not automatically make the same procedure payable under the ASC system. An ASC still has to verify its own covered-procedure listing.
ASC vs. HOPD Costs: What Patients Actually Pay
Patients often assume a surgery center will be less expensive. For many comparable procedures under Original Medicare, the ASC’s facility payment is lower than the HOPD’s. But the total bill depends on more than the facility rate.
An outpatient surgery may involve a facility claim and separate professional claims from the surgeon, anesthesiologist, or other clinicians. Pathology, imaging, implants, unexpected services, and other charges can also affect the final amount. The facility fee generally covers a bundle of operating-room and related resources; it is not necessarily a bill for every individual item used.
A real 2026 Medicare price comparison
Medicare’s Procedure Price Lookup for knee arthroscopy (code 29881) provides the following national averages for 2026. These are Medicare-approved amounts shown by the tool, not cash prices or guaranteed patient estimates.
| 2026 Medicare national average for code 29881 | ASC | HOPD |
| Facility component | $1,644 | $3,342 |
| Doctor component shown | $515 | $515 |
| Combined Medicare-approved amount | $2,159 | $3,857 |
| Listed average patient share | $431 | $771 |
The difference in the displayed combined amount is $1,698. The tool’s figures are estimates under Original Medicare and should not be treated as a quote for a scheduled procedure. They do not necessarily capture every additional service, another clinician’s charge, remaining deductible, supplemental coverage, geographic adjustment, or plan-specific cost-sharing. The patient’s medically appropriate choice of site takes priority over the comparison.
Medicare Part B deductibles and coinsurance in 2026
For 2026, the standard Part B annual deductible is $283. After the applicable deductible, Original Medicare beneficiaries generally owe 20% of the approved amount for covered ASC facility services and separately billed physician services. Some preventive services have different cost-sharing rules; for instance, screening colonoscopy arrangements may change when a polyp is removed. See Medicare’s ASC coverage page and CMS’s 2026 deductible announcement.
In an HOPD, patients generally face a hospital outpatient copayment in addition to professional-service cost sharing. For most covered outpatient hospital services, the hospital copayment for a single service cannot exceed the Medicare Part A inpatient deductible, although multiple copayments may add up to more; special rules apply in certain settings. The 2026 Part A inpatient deductible is $1,736. The cap is not a universal limit on the entire surgical episode or all separate physician charges.
Medigap can reduce some Original Medicare cost sharing, while Medicare Advantage uses plan-specific networks, approvals, and out-of-pocket terms. Commercial insurance and Medicaid can differ substantially. A patient comparing sites should request estimates that include both the facility and every expected professional claim.
Five questions to ask before choosing a surgical site
- Is this exact procedure appropriate for my health conditions and anesthesia plan at each location?
- Is the facility in my insurance network, and are the surgeon and anesthesia group also in network?
- What are the separate estimated facility, surgeon, anesthesia, and pathology charges?
- Is prior authorization required for the procedure or this particular site of service?
- What happens if a complication requires hospital transfer or unexpected care?
A written estimate is much more useful than a single advertised “surgery price.”
How Medicare Pays ASCs: The ASC Payment System
Medicare’s ASC payment methodology establishes prospective payment rates for eligible surgical procedures. A number of associated items—nursing services, operating-room use, many supplies, equipment, and certain devices—are generally packaged into the facility payment. Some ancillary services may qualify for separate payment under defined rules.
The annual ASC addenda specify approved codes, payment indicators, and rates. The rate associated with a code should not be read in isolation: multiple-procedure reductions, device rules, packaging, geographical adjustments, and other policies can change a claim’s allowed payment.
Most ASC rates are derived from OPPS relative payment weights and adjusted under ASC methodology. That shared starting point does not make the ASC rate equal to the hospital outpatient rate. CMS provides quarterly ASC approved-code and payment-rate files. Use the quarter covering the actual date of service, not an outdated January screenshot.
A key administrative distinction: a Medicare-certified ASC is generally a supplier for these purposes. It files its facility claim using the CMS-1500 or 837P professional claim format, even though it is billing a facility component. The individual clinician’s professional service can appear on a separate professional claim. CMS discusses this structure in its Medicare Payment Systems guidance.
How Medicare Pays HOPDs: OPPS and APCs
Most hospital outpatient facility services are paid through OPPS. The system groups many services into Ambulatory Payment Classifications (APCs), with payment indicators and packaging rules that determine what Medicare pays separately and what is included in a broader payment.
For selected high-cost surgical episodes, comprehensive APC (C-APC) rules can package numerous related hospital services into one primary payment. That can make a line-by-line charge comparison misleading. Two hospitals might list different charges for operating-room supplies, but Medicare’s allowed facility payment may be determined by the applicable OPPS methodology rather than by adding every listed charge.
Hospital outpatient facility claims usually use CMS-1450 (UB-04) or the 837I institutional format. Clinicians separately report their professional services under the Physician Fee Schedule when appropriate. That difference in claim formats is one reason ASC and HOPD accounts need different registration, charge-capture, coding, and claim-edit workflows.
The complication of off-campus HOPD payment
An off-campus provider-based department may be classified as excepted or nonexcepted for particular Medicare site-neutral payment rules. Whether it is hospital-owned or off campus is not enough to determine payment; facility status, service type, modifiers, and current policy all matter.
For 2026, CMS extended a site-neutral payment approach to designated drug-administration services at excepted off-campus provider-based departments, using a Physician Fee Schedule-equivalent rate for specified drug-administration APCs. This does not mean every HOPD surgical claim receives the office rate. The 2026 CMS final-rule fact sheet explains the targeted change.
ASC vs. HOPD Billing: POS Codes, Claim Forms, and Modifiers
A billing team must distinguish where a clinician performed the service from how the facility itself reports its charges. Place-of-service codes primarily describe the setting on professional claims, not the hospital’s institutional claim form.
| Setting | Typical professional-claim POS | Facility claim pathway |
| Medicare-certified ASC | 24 — Ambulatory Surgical Center | ASC facility CMS-1500 / 837P |
| On-campus HOPD | 22 — On Campus–Outpatient Hospital | Hospital facility CMS-1450 / 837I |
| Off-campus HOPD | 19 — Off Campus–Outpatient Hospital | Hospital facility CMS-1450 / 837I; applicable site-neutral rules |
| Physician office (not an ASC) | 11 — Office | Office/practice professional claim, as applicable |
These definitions come from the CMS POS Code Set. A physician office in the same building as an ASC does not become POS 24 merely because of the address; the service must actually be provided in the ASC setting. Similarly, a hospital-owned ASC that is separately Medicare-certified should not automatically be assigned HOPD POS 22.
Hospital modifiers PO and PN are not ASC POS codes
Two Medicare facility-claim modifiers are worth recognizing:
- PO: Generally identifies an excepted service furnished at an off-campus provider-based hospital department, subject to CMS reporting instructions.
- PN: Generally identifies nonexcepted services furnished at an off-campus provider-based hospital department under applicable Medicare policies.
They serve different purposes from POS 19, 22, or 24. The hospital’s claim type, provider-based status, and individual service govern how the modifiers are used. Do not append PO or PN to an ASC claim simply to show that surgery occurred away from the main hospital.
For a broader explanation of claim handoffs, edits, and payment posting, MedIntelHub’s medical billing workflow guide explains how coding and place-of-service details fit into the revenue cycle.
Practical claim example: Same procedure, different facility
A patient undergoes an outpatient knee procedure. In the ASC scenario, the center’s facility claim is submitted through its ASC supplier billing arrangement, and the surgeon’s professional claim ordinarily reports POS 24. In the HOPD scenario, the hospital reports its outpatient facility charges on an institutional claim, while the surgeon uses POS 22 or 19, depending on the department’s physical and administrative setting.
The procedure code alone cannot settle the payment question. Both claims still need accurate diagnosis reporting, date-of-service rules, correct provider identifiers, documented medical necessity, and any applicable modifiers or authorizations. A claim should not be relabeled to a “better-paying” site. It must reflect where care actually occurred.
What Changed for ASCs and HOPDs in 2026?
The 2026 OPPS/ASC final rule, issued November 21, 2025, is especially relevant to surgery schedulers and revenue-cycle teams. CMS finalized several changes effective for calendar year 2026, with later quarterly file updates possible.
1. A 2.6% base payment-rate update
CMS finalized a 2.6% payment-rate update for qualifying hospitals under OPPS and qualifying ASCs meeting relevant quality reporting requirements. This is an update factor, not a guarantee that the rate for every specific procedure will rise by exactly 2.6%. Code reassignments, wage adjustments, packaging, and other payment changes can affect individual rates differently.
2. A broader ASC Covered Procedures List
CMS reported 289 procedures added to the ASC Covered Procedures List following changes to the eligibility criteria and 271 additional codes added from procedures removed from the inpatient-only list. These are separate categories of additions in the final-rule summary. A code’s presence on the current ASC list means it may be eligible for ASC payment under applicable rules; it does not override patient selection or medical necessity.
3. A three-year phaseout of the inpatient-only list
CMS began phasing out the inpatient-only list in 2026 by removing 285 mostly musculoskeletal procedures. Removal permits consideration for hospital outpatient payment when clinically appropriate. It is not an order to discharge all such patients on the day of surgery, nor is it interchangeable with ASC CPL eligibility. The clinical admission decision remains individualized.
4. More targeted site-neutral hospital payment
As described above, specified off-campus HOPD drug-administration services became subject to a revised rate policy. Hospital systems should review excepted versus nonexcepted department status, PO/PN modifier use, and the exact affected service codes rather than apply a blanket adjustment to surgical claims.
5. Quarterly files still matter
The final rule sets the annual framework, but official code and payment files are updated during the year. A team checking a procedure performed in October 2026 should use the appropriate current-quarter ASC addenda and OPPS reference files, along with Medicare Administrative Contractor instructions and payer-specific edits.
The CMS 2026 OPPS/ASC final-rule overview is the main source for these changes. CMS has also published proposals for 2027; proposed policies should not be presented as adopted 2026 billing requirements.
Patient Safety and Choosing the Right Surgical Setting
An ASC may be an excellent option for a patient who needs a predictable outpatient operation and has health conditions that can be managed safely there. An HOPD may be preferable when the surgical team anticipates additional monitoring, more complicated anesthesia, or prompt access to hospital resources. Neither statement applies automatically to every patient.
Preoperative assessment may consider cardiopulmonary disease, sleep apnea, frailty, past anesthesia problems, medication use, bleeding risk, mobility, support at home, and the possibility of needing inpatient care. These are clinical judgments for the treating team; diagnosis lists alone do not dictate the site.
Medicare-certified ASCs must satisfy safety and operational requirements, including patient assessment and discharge processes, infection control, emergency preparedness, and medical records. Hospitals have their own participation and oversight requirements. CMS also maintains an ASC quality reporting program addressing aspects of outcomes, care processes, safety, and patient experience.
Research comparing outcomes between sites can be affected by selection bias: patients treated at ASCs may be healthier or have less complex procedures to begin with. For that reason, a lower complication rate in one setting does not by itself establish that the setting caused the difference.
For patients, it is reasonable to ask which resources are immediately available if breathing difficulties, bleeding, unexpected pain, or other complications arise. The surgical team should explain the planned recovery, discharge criteria, and transfer pathway before the procedure.
Medicare Advantage, Medicaid, and Commercial Payer Differences
Medicare fee-for-service rules provide a useful starting point, not a universal reimbursement contract.
Medicare Advantage: Coverage and cost-sharing must generally satisfy Medicare program requirements, but plan networks, authorizations, site-of-service review, and provider contracting can affect how claims are handled. Patients should not assume the Original Medicare Procedure Price Lookup predicts their plan’s copayment.
Medicaid: State programs and managed-care organizations may establish their own ASC covered services, facility reimbursement, provider enrollment, and approval rules. A policy from one state cannot be applied to every other state.
Commercial insurance: Some plans use ASC incentive arrangements or site-of-service rules intended to shift selected procedures to lower-cost facilities. Others may pay hospital-based rates under negotiated contracts. A procedure can be covered at both locations while requiring a different authorization or producing a different member deductible or coinsurance.
In each case, verify the relevant service date, network participation, both facility and clinician contracts, medical-necessity policy, authorization, and correct claim submission requirements.
Common ASC and HOPD Billing Mistakes
The most preventable problems come from assuming that every outpatient procedure follows the same claim workflow.
- Using POS 22 for a separately certified ASC. Hospital ownership or branding is not the determining factor; confirm the Medicare-enrolled entity and the actual service location.
- Using POS 24 for a physician-office procedure. An ASC and a medical office are distinct operational settings, even if they share an address.
- Treating an IPO-list removal as ASC approval. Hospital outpatient payment eligibility and ASC CPL eligibility require separate checks.
- Submitting an ASC facility service as an HOPD institutional claim. Confirm the proper Medicare supplier and claim format before submission.
- Ignoring HOPD campus status. Off-campus provider-based departments can have different reporting and payment rules.
- Unbundling packaged items without support. Review ASC packaging or OPPS/APC status indicators before billing supplies and ancillary services separately.
- Assuming the same rate applies all year. Check the quarterly file, effective date, and any payer or Medicare Administrative Contractor updates.
- Relying on the facility authorization for the surgeon’s or anesthesiologist’s service. Different providers and plan contracts can create distinct requirements.
- Quoting the facility fee as the full cost. Professional services, deductibles, anesthesia, pathology, or additional care may change the estimate.
- Confusing CPT updates with Medicare payment updates. The procedure code set and the payment-setting rules are related but separate. See MedIntelHub’s 2026 CPT changes guide.
Billing teams can reduce avoidable rework by keeping an enrollment-based facility master, mapping each location to the correct claim type and POS, and attaching a current effective-date payment reference to pre-bill edits.
A Short ASC vs. HOPD Billing Verification Checklist
Before sending a Medicare claim, confirm the facility’s certification and enrollment; the actual date and place of service; the valid procedure code and applicable list or payment status; diagnosis and documentation support; any modifiers, packaging, or multiple-procedure rules; and whether the payer requires authorization. Check that the professional and facility claims tell a consistent story without duplicating charges. Finally, reconcile the remittance against the correct payer contract or Medicare payment file.
The checklist cannot replace code-specific payer guidance, but it gives staff a reliable sequence: identify the site, verify procedure eligibility, apply the proper claim and coding rules, then evaluate payment.
Frequently Asked Questions
1. What does ASC stand for in medical billing?
ASC means ambulatory surgical center, a distinct outpatient surgical facility. For Medicare facility payment, it must meet applicable participation and enrollment requirements.
2. What does HOPD stand for in healthcare?
HOPD means hospital outpatient department. It provides services to patients who have not been formally admitted as hospital inpatients, and it may be located on or off the main campus.
3. Are ASCs and HOPDs the same thing?
No. The facilities have different Medicare certification or provider arrangements, payment systems, and typical facility claim formats, even when they perform a similar operation.
4. Is outpatient surgery always cheaper at an ASC?
Not always. ASC Medicare facility rates are often lower for comparable procedures, but the patient’s final payment depends on insurance, deductibles, facility and professional charges, and other services.
5. Can a hospital own an ASC?
Yes. A hospital-owned ASC can be separately certified and enrolled for ASC payment. Ownership does not automatically make it an HOPD.
6. What is POS 24 used for?
POS 24 identifies an ambulatory surgical center on a professional claim when the service was actually provided in that setting.
7. What is the difference between POS 19 and POS 22?
POS 19 identifies an off-campus outpatient hospital setting; POS 22 identifies an on-campus outpatient hospital setting. These are place-of-service indicators on professional claims.
8. Do ASCs send UB-04 claims to Medicare?
Medicare-certified ASCs generally submit ASC facility claims using 837P or CMS-1500, while hospital outpatient departments generally use 837I or UB-04 for facility billing. Other payers may specify their own submission processes.
9. Does Medicare Part B cover ASC surgery?
Part B covers facility fees for approved ASC surgical procedures when the applicable coverage rules are met. Patient cost-sharing and separately billed professional fees can still apply.
10. Does a procedure being on the ASC Covered Procedures List guarantee payment?
No. Code eligibility is not the same as documented medical necessity, payer authorization, network eligibility, or clean claim submission.
11. Can a patient stay overnight in an ASC?
The Medicare ASC model is for patients not expected to need hospitalization, with services generally anticipated to last no more than 24 hours after admission. An unexpected complication may require extended care or hospital transfer.
12. Are HOPDs always located inside a hospital?
No. Qualifying off-campus provider-based hospital departments also exist. Their reimbursement and reporting can be affected by site-neutral payment policies.
13. Why might I get two bills after outpatient surgery?
A facility and a surgeon typically bill separately, and anesthesia or pathology professionals may submit additional claims. Patients should compare each explanation of benefits with the corresponding provider bill rather than assuming duplicate charges.
14. What changed for ASCs in 2026?
CMS finalized a 2.6% update factor for qualifying ASCs and expanded the ASC Covered Procedures List, including specified additions linked to inpatient-only list changes. Eligibility and rates remain code- and date-specific.
15. Does removing a procedure from the inpatient-only list make ASC surgery mandatory?
No. The change allows consideration of outpatient hospital payment when medically appropriate. ASC eligibility is separate, and the clinician still determines an appropriate care setting.
16. Which surgical setting is safer?
Safety depends on the procedure, patient, staffing, monitoring capability, and emergency response resources. A clinician familiar with the individual patient’s risks should determine whether an ASC or HOPD is appropriate.
Choosing the Right Site—and Coding It Correctly
An ASC and an HOPD may both offer outpatient surgery, but they are not interchangeable billing labels. A separate ASC facility claim, a hospital outpatient facility claim, and the surgeon’s professional claim each have their own role. The setting affects coverage checks, Medicare payment calculations, and potentially patient costs.
For patients, the useful comparison combines the clinical plan with estimates for all expected bills. For billing teams, the starting point is the facility’s real enrollment status and the procedure’s eligibility for the actual date of service. Once those facts are correct, the coding, place-of-service, and reimbursement checks become much easier to defend.
