Hospital Inpatient and Observation Care: 3.7× the Insurer's Own Benchmark
In the last quarter of 2025 the median prevailing offer in hospital inpatient and observation care disputes was 3.7× the qualifying payment amount — the figure the plan itself calculated. Across the second half of 2025, certified IDR entities decided 26,735 payment determinations in this category, covering 58,380 items or services.
What the Federal Data Says About Hospital Inpatient and Observation Care
How to read this. The qualifying payment amount is the plan's own calculated benchmark — generally the median contracted rate for the service in the geographic area. A median prevailing offer of 3.7× QPA means that in half of the decided disputes in this category, the offer the certified IDR entity selected was at least 3.7 times what the plan had calculated. It is a measure of the gap between the plan's benchmark and what an independent entity found defensible. It is not a prediction, a guarantee, or an average recovery for any particular practice, and it does not include disputes that were found ineligible or that closed before a determination. CPT range for this category: 99217–99239 (hospital inpatient and observation care, including admission and discharge services).

Why Hospital Inpatient and Observation Care Claims End Up Out of Network
Hospitalists and observation-care physicians are hospital-based by definition: the patient is admitted to a facility and cared for by whoever is on service. Where the facility is in network and the physician is not, the No Surprises Act protections apply and the patient cannot be balance billed.
Two features shape disputes in this category. First, observation status is itself contested territory — whether an encounter is billed as observation or inpatient changes the code set and therefore the benchmark the plan applies. Second, these are time-and-complexity coded services, so the documentation that supports the level billed is exactly the documentation a certified IDR entity will weigh.
Claims here are individually modest and numerous, which is the profile where batching decides whether disputing is worth doing at all — particularly now that the administrative fee is $15 per party rather than $115.
Deciding Whether a Claim Is Worth Disputing
Three things determine whether a specific claim belongs in federal arbitration, and none of them is the specialty itself.
1. Is the claim eligible?
Roughly one in five disputes initiated in 2025 was found ineligible — the single largest source of wasted effort in this process. Eligibility turns on whether the item or service falls under the federal protections rather than a state process, whether open negotiation ran its full 30 business days, and whether the dispute was filed within the four-business-day window that follows. Getting this wrong costs the fee and the claim.
2. Does the arithmetic work?
Since June 11, 2026, the administrative fee is $15 per party per dispute, down from $115. The certified IDR entity fee is set within a range published annually by the Departments and is paid by the non-prevailing party. Against those costs, the relevant question is the gap between the plan's payment and a defensible value for the service — and the federal data shows that gap by claim size is largest on smaller claims, not larger ones.
3. Can the claims be batched?
Qualifying claims may be submitted together in a single dispute. For a hospital inpatient and observation care practice generating similar claims against the same plan, batching is usually what turns a marginal economic case into a clear one.
We review claims against these three tests before anything is filed, and we are paid only out of what is actually recovered. If the claims do not clear the tests, we say so.
