How we verify your benefits before surgery
Once your surgeon’s office sends the case to our scheduling team, our billing department runs a verification of benefits (VOB) with your insurance carrier. The VOB answers the practical questions that determine what you’ll pay out of pocket:
Is the planned procedure a covered benefit? — confirmed against your specific plan and CPT code.
Is DOSC in-network for your plan? — and separately, is your surgeon in-network? (These are two different contracts.)
Has your deductible been met? — we pull current-year accumulator data from the carrier.
What is your co-insurance or co-pay for outpatient surgery? — and how close are you to your out-of-pocket maximum?
Is prior authorization required? — and if so, has it been obtained? (We coordinate with your surgeon’s office on this.)
A patient financial counselor then calls you to review the estimate, collect any expected patient responsibility (often on the day of surgery), and answer questions. You’ll receive a written summary of the benefits in your pre-op packet.
Good Faith Estimates & out-of-pocket costs
Under the federal No Surprises Act, patients without insurance (or who choose not to use their insurance) receive a written Good Faith Estimate of expected charges before their scheduled service. Insured patients can also request a written estimate based on the verified benefits. See our dedicated Good Faith Estimate page for the full policy.
A few important clarifications about estimates:
The facility estimate covers the facility portion only — the operating room, nursing staff, supplies, recovery, and other services billed by DOSC.
Professional fees are billed separately by the surgeon, the anesthesia provider, and (if applicable) the pathology lab. Those offices bill you directly on their own timeline.
Implants, hardware, and specialty supplies may be billed separately depending on the procedure — we note these explicitly on the estimate.
Unexpected findings during surgery (additional procedures discovered intraoperatively) can change the final charges. When this happens we follow up with you and the carrier promptly.
What to bring to pre-op registration
Our pre-op nurse will call you the day before your surgery with case-specific instructions (fasting, medication hold, ride home, etc.). On the morning of surgery, please bring:
Government-issued photo ID (driver’s license, state ID, or passport)
All current insurance cards — primary and secondary
Your surgeon’s H&P (history & physical) and medical clearance, if not already faxed
Any pre-op labs, EKG, imaging, or cardiac clearance documentation
A complete list of current medications with doses and frequency
Your authorization letter or referral, if your plan requires one
A responsible adult driver for discharge — you cannot drive home after anesthesia
Payment method for any expected patient responsibility (card, cash, or check)
Self-pay & medical-lien options
If you don’t have insurance, or if your insurance won’t cover the procedure your surgeon has recommended, we have two pathways to help:
Self-pay with a bundled facility rate. We provide a transparent Good Faith Estimate and a discounted self-pay rate for most common outpatient procedures. Payment plans are available through our third-party patient financing partner.
Medical lien. For personal-injury, auto-accident, and select workers’ compensation cases represented by an attorney, DOSC accepts medical liens — surgical care is provided with payment deferred until settlement. See our For Attorneys page for the full lien process.
Questions about coverage?
Our billing team answers coverage and VOB questions Monday through Friday, 7:00 AM to 5:00 PM. We’re happy to call your carrier on your behalf, translate a denial letter, or walk through your Good Faith Estimate line by line.
Insurance network status changes periodically and this page is updated as contracts change. The controlling answer for your specific plan is the written verification of benefits our billing team provides before your surgery date.

How DOSC handles surprise billing protections under the No Surprises Act
How DOSC handles surprise billing protections under the No Surprises Act
The No Surprises Act, effective January 2022, established federal protections that limit what patients can be billed for certain services received at in-network ambulatory surgery centers. Downey Outpatient Surgery Center participates in these protections and provides patients with written disclosures before scheduled procedures, so the financial picture is clear before the day of surgery.
The core protection works like this: when a patient receives covered care at an in-network ASC, ancillary providers involved in that care (anesthesiologists, pathologists, radiologists, assistant surgeons) cannot send a separate balance bill at out-of-network rates without the patient's informed, written consent. The patient's responsibility for those ancillary services is limited to in-network cost-sharing amounts, even if the individual provider does not contract with the same insurance plan. This closes a billing gap that historically caught patients off guard after outpatient procedures.
DOSC's billing office works through several steps to keep patients informed. Before a scheduled surgery, the team verifies insurance benefits, confirms in-network status for the facility, and identifies which ancillary providers are expected to participate in the case. Patients receive a good-faith estimate that lists anticipated charges from the facility, the surgeon, and ancillary providers when those amounts can be reasonably projected. If a provider involved in the procedure is out-of-network and the patient would otherwise be asked to waive No Surprises Act protections, DOSC will not request that waiver for emergency or ancillary services covered by the law.
What patients can do if a bill looks wrong
Patients who receive a bill that appears to violate surprise billing protections have several options. The first step is to contact the DOSC billing office directly; many disputed charges turn out to be coding or insurance-processing issues that resolve once the claim is reviewed. If the question involves a separate provider's bill rather than the facility charge, patients can ask that provider's office to confirm whether the charge complies with the No Surprises Act.
For unresolved disputes, the federal No Surprises Help Desk operates a complaint process at 1-800-985-3059, and the Centers for Medicare and Medicaid Services maintains a patient-facing portal where bills can be reviewed for compliance. California patients also have additional state-level protections under AB 72, which predates the federal law and continues to apply in parallel for many fully insured plans regulated by the state. Self-funded employer plans generally fall under federal jurisdiction, so the applicable rules depend on plan type, a detail the billing office can help confirm.
Patients are encouraged to keep all written estimates, explanations of benefits, and itemized statements together in one place. Comparing the good-faith estimate to the final bill is the fastest way to identify a discrepancy worth raising. DOSC's billing staff is available by phone during business hours and responds to written inquiries within standard timeframes for medical billing offices.

How prior authorization works for outpatient surgery and what can delay your scheduled date
Prior authorization is the review process your insurance plan uses to confirm that a planned outpatient procedure is covered before the surgery date is held. For most outpatient cases scheduled through our office, the authorization pathway begins the moment a procedure is recommended and continues until written approval is on file. Understanding the sequence helps patients anticipate timing and avoid the common bottlenecks that push surgery dates later than expected.
Once a procedure is recommended, our surgical scheduling team submits a request to the insurance carrier that typically includes the procedure code, the diagnosis code, recent clinic notes, and any imaging or conservative-care documentation the plan requires. Carriers then route the request to a medical reviewer, who compares the submission against the plan's coverage criteria. Standard turnaround is generally five to fifteen business days, though some plans respond sooner and others request additional records before issuing a decision.
Several factors commonly delay an authorization. Missing conservative-care documentation, such as a record of physical therapy or prior injections, is the most frequent cause. Outdated imaging, a mismatch between the submitted diagnosis code and the procedure code, or a change in the patient's insurance plan during the review window can also reset the clock. When a carrier requests peer-to-peer review, the surgeon must schedule a call with the plan's medical reviewer, which can add several business days depending on availability on both sides.
Patients can help keep the timeline on track by confirming that insurance information on file is current, responding promptly when our team requests updated records, and notifying us immediately if coverage changes between the initial visit and the scheduled surgery date. If a plan denies the initial request, an appeal is often available and the clinical team will advise on the documentation needed to support it.

What an outpatient surgery cost estimate includes before your procedure date
An outpatient surgery cost estimate is a written summary that helps patients understand what a scheduled procedure is likely to involve financially before they arrive. It is prepared by the billing team once a procedure is on the calendar, and it is meant to remove surprises rather than to serve as a final bill.
A complete outpatient surgery cost estimate generally breaks the total into a few distinct parts. Each part is billed by a different entity, which is why patients sometimes receive more than one statement after a single visit. Reviewing these categories ahead of time helps clarify which charges are expected and which questions to raise.
Facility fee: the charge for use of the surgical suite, equipment, and nursing staff during the procedure.
Provider fee: the professional charge for the surgeon and, when applicable, the anesthesia provider.
Diagnostic and pre-operative services: imaging, measurements, or laboratory work ordered before the date to confirm the plan.
Supplies and implants: any devices or materials used during the procedure itself.
The estimate also reflects how insurance is expected to apply. The billing team verifies benefits in advance and lists the projected deductible, coinsurance, and any copay that may be due. Because plans differ, the estimate typically shows both the negotiated rate and the portion the patient is expected to owe after coverage is applied. Patients who have not met their annual deductible often see a higher out-of-pocket figure than those who have.
It is helpful to understand what an estimate is not. Estimates are based on the planned procedure and the information available at the time. If the clinical team adjusts the approach during surgery, or if additional services become necessary, the final charges can differ. An estimate is a good-faith projection, not a promise of the exact amount.
Patients preparing for a procedure date can take a few practical steps. Confirm that the practice and the surgical facility are both in-network for the specific plan. Ask whether prior authorization has been obtained. Request the estimate in writing, and keep it alongside the plan's summary of benefits so the two can be compared. If a payment plan or financial assistance may be needed, the billing team can review options before the date rather than after.
Bringing questions to the pre-operative appointment tends to make the process smoother. The clinical and billing teams can walk through each line, explain the terminology, and note where a figure is an estimate versus a confirmed charge.
