Ambulatory Surgery Center Financial Clearance Software

Financial Clearance in a Ambulatory Surgery Center Practice

Clearance at a surgery center works case by case. When a case is booked, a 270 eligibility inquiry goes to the payer, and the 271 reply returns the facility deductible, coinsurance and network status. Each planned CPT code is then checked against the payer's site rules. For Medicare, that means the ASC covered procedures list and the code's payment indicator. For many commercial and Medicare Advantage plans, it means an approval that matches the code and the site. Requests go out over the X12 278 or the payer's portal, and the case is held while a request is pending. In the ten states in Medicare's ASC test, five service groups need a provisional affirmation. Without one, the claim faces prepayment review. Last, the estimate combines the facility rate with the patient's remaining benefits. Ambulatory surgery center financial clearance then passes the cleared case to ASC patient scheduling to lock in the slot.

Why Is Financial Clearance Different in Ambulatory Surgery Center?

A surgery center bills its own facility claim, so it cannot lean on the surgeon's approval. Many authorizations are tied to a code and a site of care. A hospital outpatient approval may not carry over to the ASC, and an approval for one CPT code does not cover a different code added in the operating room. Clearance has to check what the center itself will bill.

Medicare adds rules of its own. It pays an ASC only for procedures on its ASC covered procedures list, which changes every year and again in quarterly updates. For CY 2026, CMS added procedures and loosened several of the list's general exclusions. A procedure off the list leaves the patient liable for the facility charges. In ten states, Medicare is also testing prior authorization for certain ASC procedures.

Patient cost is the last piece. The facility bill is separate from the surgeon's, so a second bill often surprises patients. Medicare screening colonoscopies have their own cost rules, even when a polyp comes out. Uninsured and self-pay patients are owed a good faith estimate. Insured patients are shielded from surprise bills by out-of-network anesthesia or pathology at an in-network ASC. Financial clearance in an ASC has to get each of these right before the date.

What Ambulatory Surgery Center Financial Clearance Software Handles

Medicare ASC prior authorization demonstration

Since early 2026, ASCs in ten states can ask Medicare for prior authorization for five service groups: blepharoplasty, botulinum toxin shots, panniculectomy, rhinoplasty and vein ablation. The states are California, Florida, Tennessee, Pennsylvania, Maryland, Georgia, New York, Texas, Arizona and Ohio. Asking is voluntary. A claim sent without it goes to prepayment medical review. (CMS Prior Authorization Demonstration for Certain Ambulatory Surgical Center (ASC) Services)

Provisional affirmation and the UTN

The MAC returns a provisional affirmation, a partial affirmation or a non-affirmation, each with a unique tracking number. A non-affirmed request can be corrected and sent again as often as needed, and the UTN is saved on the case for the claim. (CMS FAQs: Prior Authorization Demonstration for Certain ASC Services (December 2025))

ASC covered procedures list and payment indicators

Medicare pays the facility only for codes on the ASC list. Codes with payment indicators C5, E5, U5 or X5 are not paid and the patient is held liable for the facility charges, so they are flagged when the case is booked. (Medicare Claims Processing Manual, Chapter 14: Ambulatory Surgical Centers)

Screening colonoscopy cost-sharing

For a Medicare screening colonoscopy, no deductible applies, even if tissue is removed in the same visit. Coinsurance is being phased down and ends in 2030. Estimates for these GI cases follow that rule, not the usual Part B cost-sharing. (Medicare Claims Processing Manual, Chapter 14: Ambulatory Surgical Centers)

Surprise billing protections at the ASC

Under the No Surprises Act, an ASC is a facility for non-emergency care. At an in-network ASC, out-of-network anesthesia, pathology and radiology cannot balance bill an insured patient. Their bills are held to in-network cost-sharing, and counselors can tell patients so. (CMS No Surprises Act: Overview of Key Consumer Protections)

Payer prior authorization rules (CMS-0057-F)

Medicare Advantage plans, Medicaid and CHIP programs, and plans on the federal exchanges began facing faster prior authorization deadlines in 2026 and must offer a prior authorization API in 2027. They must also give a specific reason when they deny a request. (CMS Interoperability and Prior Authorization Final Rule (CMS-0057-F))

How Does Ambulatory Surgery Center Financial Clearance Software Work?

1. 1. Run eligibility at booking

   A 270 inquiry goes out when the case is booked, and the 271 reply shows the facility deductible, coinsurance and network status. Coverage is checked again in the background as the date gets close.

2. 2. Check each code against the site

   Planned CPT codes are checked against the ASC list and their payment indicators for Medicare, and against plan rules for other payers. A code that cannot be paid at the ASC is flagged for the surgeon's office.

3. 3. Request and track approvals

   Prior authorization requests go out over the 278 or the payer portal with the clinical notes the payer asks for. The case stays on hold until an approval or a UTN is on file.

4. 4. Build the estimate

   The facility rate is combined with the patient's remaining deductible and coinsurance. Self-pay patients get a good faith estimate, and insured patients see what they will owe the center.

5. 5. Release the case

   Once coverage, approvals and the estimate are set, the hold is lifted and the case is confirmed. The approval number follows the case into ASC medical billing.

Who Uses It in a Ambulatory Surgery Center Practice

• Authorization coordinator: One queue of cases that need approval, with each request's status and tracking number on the case, and pre-op forms from patient intake next to the clinical notes.
• Financial counselor: Estimates built from live benefits and the facility rate, ready to go over with the patient before surgery.
• Surgeon's office liaison: Early notice when a code is not payable at the ASC or an approval is missing, while the case can still be moved or fixed.
