Can gastroenterology claims use federal IDR?

Where gastroenterology care qualifies

For scheduled care, the Act protects patients at hospitals, hospital outpatient departments, critical access hospitals, and ambulatory surgical centers, and for emergency care at hospital and freestanding emergency departments. When the site is in network with the patient's plan, an out-of-network clinician working there cannot bill the patient more than in-network cost sharing for covered services, and a payment the clinician disputes goes to open negotiation and then federal IDR. The 2025 files show where GI claims land. Of the 1,446 gastroenterologist-filed disputes, 600 include a line at a surgery center, 593 at a hospital inpatient unit, 214 at a hospital outpatient department, and 54 at an emergency department. Among the 3,032 procedure disputes, 121 include an emergency department line (3.99 percent), and among the 64,022 sedation disputes, 4,597 include a hospital inpatient line (7.18 percent) and 658 an emergency department line (1.03 percent).

Who can be asked to waive

Anesthesiology, pathology, radiology, emergency medicine, assistant surgery, hospitalist, intensivist, and neonatology services, along with diagnostic services such as laboratory and imaging, are ancillary services. At an in-network facility, an out-of-network ancillary clinician cannot use the notice and consent form at all. That covers the sedation work behind most GI volume and the pathologists who read the biopsies; a surgical pathology exam (88305) appears in 105 of the 3,032 procedure disputes. A gastroenterologist is not an ancillary clinician for a scheduled procedure, so the physician can give written notice and get a signed consent at least 72 hours before the service, or when the service is booked if that falls inside 72 hours. Once the patient consents, the patient can be billed and the claim falls outside federal IDR. The exception does not cover unforeseen urgent needs that arise during the visit, or services no in-network clinician at the facility can provide.

What the Act does not reach

A physician's office is not a covered facility, and the facility-based protections do not reach a service performed in one. In the 2025 files 5 procedure disputes and 212 sedation disputes list a physician's office, though a dispute can also include lines at covered facilities. Medicare, Medicare Advantage, Medicaid, and TRICARE claims are excluded, and a facility that is itself out of network is outside the Act for scheduled care. Where a state runs its own surprise billing process, fully insured plans follow it, while self-insured plans, which state laws generally cannot reach, use the federal one. Self-insured plans were the plan type in 1,221 of the gastroenterologist-filed disputes (84.4 percent), 2,436 of the procedure disputes (80.3 percent), and 49,605 of the sedation disputes (77.5 percent), and fully insured group plans in 95, 262, and 6,025. California and New York, which produced 98.55 percent of the gastroenterologist-filed disputes, each run their own process for fully insured plans.

Deadlines and filing costs

Open negotiation must start within 30 business days of the plan's initial payment or denial, and a request for federal IDR must follow within 4 business days after the negotiation period ends. Confirm current requirements for your claim before relying on a date. Each party pays a $15 administrative fee for every dispute and fronts the IDR entity's fee, which is returned to the winner. In the 2025 files the median procedure dispute took 28 days to decide and the median sedation dispute 31. Lido IDR confirms the setting and plan type and counts the dates, then files for a flat fee per arbitration, and offers are priced from the decided results at idrexplorer.com.
