IDR for hospitalists: the hospital medicine record
What admission, rounding, and observation lines won in 2025, and why the regulations put hospitalist claims beyond the reach of any consent form.
Hospital medicine is the fastest growing bucket in federal IDR: quarterly dispute volume rose from 3,012 in the third quarter of 2024 to 18,980 a year later, and the 2025 files hold 60,968 disputes with hospitalist line items. Providers won 85.2 percent of decisions at a median of 8.13 times the QPA. This site explains why hospitalists hold an unusually strong position under the No Surprises Act, grounded entirely in the published record.

Federal IDR is the No Surprises Act arbitration process for out-of-network claims. Hospitalist line items appear in 60,968 disputes in the 2025 files; providers won 85.2 percent of decided ones at a median of 8.13 times the QPA. The regulations name hospitalists as a category whose protections can never be waived by patient consent, so every out-of-network commercial claim at an in-network facility is potentially in scope.
The fastest growth in the files
No specialty bucket grew faster in the published record than hospital medicine. Quarterly volume went from 3,012 disputes in the third quarter of 2024 to 18,980 in the third quarter of 2025, more than sixfold, and the full 2025 files hold 60,968 disputes with hospitalist line items. Providers won 85.2 percent of decisions. The bucket median QPA was $128.12 against a $616 median decided award; payer offers sat at exactly the benchmark, and decisions came back in about 30 days at the median.
Admission to discharge, line by line
The hospitalist record is the E/M ladder itself. Initial hospital care at the highest level (99223) appeared in 11,595 disputes, won 85.67 percent, and paid a median decided award of $1,000 against a $238.20 QPA. Subsequent care lines 99232 and 99233 ran 9,794 and 8,973 disputes with win rates near 85 percent and medians of $292 and $462.20. Discharge management over 30 minutes (99239) added 6,386 disputes. The outlier is observation care: G0378 lines appeared in 14,331 disputes and paid a median decided award of $14,400 against a $1,055.40 QPA.
Named on the never-waivable list
For most scheduled care at an in-network facility, a payer can argue the patient signed away surprise-billing protection. Not here. The No Surprises Act regulations list the categories where notice-and-consent waivers are simply unavailable, and items and services furnished by hospitalists appear on that list by name, alongside emergency care, anesthesiology, pathology, radiology, neonatology, diagnostics, assistant surgeons, and intensivists. A hospitalist claim on a commercial plan at an in-network hospital either qualifies or it does not; no consent form changes the answer.
Payers, geography, and filing costs
Blue Cross Blue Shield of Texas ran 12,976 hospitalist disputes decided at a 10.33 median multiple, Anthem 6,861 at 10.67, and Aetna 6,550 at an 89.69 percent provider win rate. UnitedHealthcare is the outlier: 11,260 disputes decided at just 3.85 times the QPA. Texas holds 22,090 disputes, California 5,979, and New Jersey 3,874 at a 29.77 median multiple. A filing carries a $15 administrative fee for each party and a certified IDR entity deposit that the winner recovers; Lido IDR handles the whole dispute for a flat fee per arbitration, with every offer anchored to the published record at idrexplorer.com.
Common questions
Can hospitalists use federal IDR?
Yes, and more cleanly than almost any other specialty. Hospitalist work is facility-based by definition, and the No Surprises Act regulations name hospitalists as a category whose protections patients can never waive by consent. Out-of-network claims on commercial plans at in-network hospitals qualify; Medicare, Medicare Advantage, and Medicaid claims do not.
What do hospitalist claims pay in federal IDR?
Providers won 85.2 percent of the 60,968 hospital medicine disputes in the 2025 files, at a median of 8.13 times the QPA. High-level admission lines (99223) paid a median of $1,000, and observation care lines (G0378) a median of $14,400 against a $1,055.40 benchmark.
Can a patient consent form waive a hospitalist claim?
No. The regulations put hospitalist items and services on the No Surprises Act's never-waivable list, the same protected status given to emergency care, anesthesiology, pathology, radiology, and intensivists. A payer denying a hospitalist line on waiver grounds is misapplying the rule.
Do Medicare Advantage patients count toward hospitalist IDR claims?
No. Original Medicare, Medicare Advantage, Medicaid, and TRICARE all sit outside the federal process. For a hospitalist group that can feel like most of the census, but the commercial out-of-network slice that remains decided at a median of 8.13 times the QPA in 2025.
What does it cost a hospitalist group to file?
Each party pays $15 in administrative fees per dispute. The certified IDR entity also collects a deposit of a few hundred dollars, which the winner gets back. Percentage vendors take 15 to 25 percent of recoveries across an entire census; Lido IDR files for a flat fee per arbitration.
