IDR for neurosurgeons: the neurosurgery record
What decided neurosurgical disputes paid, which cranial and spine claims qualify, and why a $291 benchmark meets a $44,950 award.
Neurosurgery holds one of the strongest published records in federal IDR: an 88 percent win rate across 19,990 disputes in the 2023 through 2025 files, with a median decided award of $25,000. On the biggest clean 2025 code, lumbar decompression, the median award was $44,950 against a $291.54 payer benchmark. This site lays out how neurosurgery groups can use the process, with every claim traced to the published record.

Federal IDR is the No Surprises Act arbitration process for out-of-network claims. Neurosurgery line items appear in 19,990 disputes across the 2023 through 2025 public use files; neurosurgeons won 88 percent of decided ones, with a median award of $25,000. In 2025, the lumbar laminectomy and decompression line (63047) alone appeared in 2,699 disputes, won 84.1 percent, and paid a median decided award of $44,950 against a median QPA of $291.54.
Where neurosurgery meets the No Surprises Act
Two categories of neurosurgical claims are protected. Emergency care is the first: the craniotomy on call, the evacuated subdural, cauda equina at 2 a.m. When the operating surgeon is out-of-network, those claims qualify with no conditions attached. The second is planned surgery performed at an in-network hospital or at an ambulatory surgery center, protected by default unless the patient signed a compliant notice-and-consent waiver ahead of the case. Co-surgeons and assistant surgeons sit on the statute's never-waivable list, so their claims qualify regardless of paperwork.
The neurosurgery numbers
Across 2023 through 2025, 19,990 published disputes carried neurosurgery line items. Of the ones arbitrators decided, neurosurgeons took 88 percent, at a median decided award of $25,000, among the largest of any specialty. The cleanest high-volume 2025 code tells the sharper story: lumbar laminectomy with decompression (63047) appeared in 2,699 disputes, won 84.1 percent of decisions, and paid a median decided award of $44,950 against a median QPA of $291.54, a multiple above 60.
Why the multiples run so wide
The qualifying payment amount comes from the payer's own contract data: the median rate it pays in-network for the same code in the same market. Complex spine and cranial codes are rare in network contracts and often priced nominally when they appear, which produces benchmarks in the hundreds for procedures that take hours of operating time and years of training. Arbitration asks what the specific case was worth, and arbitrators may weigh the provider's training, the acuity, and the complexity. On the decided record, they answered with five-figure awards for neurosurgical work far more often than not.
The cost side of a neurosurgical filing
Out-of-pocket costs stay small: $15 in administrative fees per party per dispute, plus the certified IDR entity's charge of a few hundred dollars, refunded to whichever side prevails. Representation is the real line item: 15 to 25 percent contingency on a $44,950 decompression award is $6,700 to $11,200 for a single case. Lido IDR files for a flat fee per arbitration instead. Every statistic on this site comes from the CMS public use files, explorable at idrexplorer.com.
Common questions
Can neurosurgeons use federal IDR?
Yes. Emergency cranial and spine work qualifies whenever the surgeon is out-of-network. Planned procedures at in-network hospitals or surgery centers qualify too, unless the patient signed a compliant notice-and-consent waiver. No waiver can reach assistant surgeons or co-surgeons. Medicare, Medicaid, and office visits sit outside the process.
What do neurosurgeons win in federal IDR?
The 2023 through 2025 record shows neurosurgeons winning 88 percent of decided disputes at a median award of $25,000. The 2025 lumbar decompression line (63047) paid a median decided award of $44,950 against a median QPA of $291.54.
Why are neurosurgery IDR awards so much higher than the QPA?
The QPA reflects median contracted rates, and complex neurosurgical codes are often priced nominally in network contracts. Arbitrators price the actual case, weighing acuity, complexity, and the surgeon's qualifications, which in 2025 put decided decompression lines at a median above 60 times the benchmark.
Does a consent form remove a neurosurgery claim from IDR?
Only for planned, non-emergency surgery where the facility gave compliant notice 72 hours or more ahead, attached a good faith estimate, and an in-network alternative actually existed. No form can waive an emergency case, an assistant surgeon, or a co-surgeon.
What does it cost a neurosurgery group to file?
Administrative fees are $15 per party per dispute, and the certified IDR entity deposit of a few hundred dollars is refunded to the winner. Contingency vendors keep 15 to 25 percent of awards, which reaches five figures per decided case at neurosurgical sizes; Lido IDR charges a flat fee per arbitration.
