Most practices assume that if their billing is accurate and their claims are clean, their reimbursement reflects what the market pays. The data from a recent Neolytix-hosted roundtable on payer contract negotiations suggests otherwise. Among providers in the same city, billing the same CPT codes to the same payer, reimbursement rates varied by 30 to 60 percent. The difference had nothing to do with quality scores, patient volume, or specialty mix. It came down entirely to negotiating history.
That gap is not an anomaly. It is the default state for practices that have not actively benchmarked and renegotiated their payer contracts. And because it does not show up as a denial or a billing error, most practices never know it is there.
The Problem Is Invisible Until You Look for It
Payer reimbursement rates erode quietly. Commercial payers typically apply annual CPI adjustments averaging 3 to 4 percent, while practice operating costs inflate at 6 to 8 percent annually. Every contract cycle that auto-renews without renegotiation means the contract is worth measurably less in real terms — not because anything changed in the fee schedule, but because the cost baseline moved and the rates did not.
What makes this harder to detect is where the revenue loss concentrates. A practice can appear adequately reimbursed at the top line while losing significant money on its highest-volume procedures. The gap does not distribute evenly across all codes. It concentrates in the specific CPT codes that make up the bulk of a practice’s billing activity, which are often also the codes that have gone longest without scrutiny.
This is the structural problem that routine billing oversight does not catch. Denial management surfaces claim-level errors. Accounts receivable monitoring tracks payment delays. Neither reveals whether the contracted rate for a given procedure is 20 percent below what a comparable practice down the street is collecting from the same payer for the same service.

Payer Contract Negotiation
Payers Already Know Where You Stand
The roundtable surfaced something providers rarely hear stated directly: payers are not passive actors in the reimbursement relationship. They maintain detailed data on which practices challenge their rates and which accept whatever they are offered — and that behavioral profile shapes what a payer will offer at renewal.
Raj Inamdar, Managing Director of Therapy Center of New York, described the dynamic from the provider side: “With some insurers we have more information on their position, and with some it’s more of a stone wall. Our goal now is to leverage the market data and allow the insurers who are more challenging to provide more transparency in where they’re coming from — and if there’s things they want us to improve, they should tell us. We’re more than willing to accommodate if we know where the disagreement is.”
That willingness to engage only goes so far without data to support it. Practices that have historically auto-renewed without pushback are not offered the same rates as those that have consistently brought benchmarking evidence to the table. The asymmetry is structural. It is not in a payer’s financial interest to volunteer rate increases to providers who have demonstrated they will not ask for them.
This has a compounding effect. The longer a practice goes without challenging its rates, the wider the gap between its contracted reimbursement and market rates becomes. Three-year contract terms with automatic renewal clauses mean each renewal cycle is effectively the only opportunity to correct years of rate drift. Missing that window does not just defer the correction — it locks in another cycle of below-market reimbursement.
What the Data Actually Shows
The Neolytix analysis presented at the Helix roundtable put specific numbers to a problem that is often described only in general terms.
The rate spread is wider than most providers expect. For the same CPT code, billed to the same payer, within the same metro area, the difference between the lowest and highest reimbursing provider was 30 to 60 percent. That spread is not explained by quality or volume differences. It is explained by contract history.
Revenue loss concentrates at the code level, not the contract level. In one engagement, a CPT-level audit recovered more than $170,000 in a single review cycle. The codes were billed correctly. The claims were not denied. The rates were simply below where they should have been, and no one had compared them against market benchmarks until that point.
The same practice can be underpaid by one payer and a top performer with another. A behavioral health group reviewed at the roundtable was the lowest-paid Aetna provider in its market and simultaneously 7 to 13 percent above all Cigna competitors — same city, same year. Inamdar recognized a version of this in his own organization: “One year we may have some gold preferred star from one insurer, and then with the same provider base the next year, we don’t have it, and then it comes back. We don’t know how they’re making those determinations — and those potentially could factor into reimbursements.” Two completely different reimbursement outcomes from the same practice, requiring two completely different strategies.
Signing the contract is not the finish line. Post-contract revenue loss is a distinct and underappreciated problem. Inamdar described a recurring issue his group encounters: “Sometimes they have this loophole where a subsidiary plan, which they didn’t tell you about, needs charts submitted for all the claims — otherwise they’re going to deny all of them. And to fix it, that’s going to take five months.” Denials, missing CPT codes, and subsidiary plan loopholes are where revenue gets lost after the negotiation ends. Understanding how denials interact with contracted rates is part of protecting what was won at the table.
The roundtable also surfaced a case study that illustrates what CPT-level benchmarking can recover in concrete terms. An orthopedic surgery group operating under a UnitedHealthcare contract was 18 percent below market on its top 20 billed codes. The codes were accurate. The claims were processing. The rates had simply never been challenged. After benchmarking and renegotiation, the group added $280,000 in annual revenue — without seeing a single additional patient.
How Transparency in Coverage Data Changed the Negotiating Table
For most of the history of payer contracting, providers negotiated in the dark. Payers maintained detailed databases of what every provider in their network was paid for every code — and providers had no equivalent visibility into what anyone else was receiving. That asymmetry is what made “your rates are competitive” a claim providers could not easily challenge.
The federal Transparency in Coverage rule, finalized in 2020 and enforced from July 2022, fundamentally shifted that dynamic. Under the rule, most commercial health plans are required to publish machine-readable files disclosing their in-network negotiated rates by CPT code and by provider, updated monthly. For the first time, a provider can look up what a payer is reimbursing a competitor in the same market for the same service — in actual dollar terms.
CMS strengthened these requirements further for 2026, replacing estimated allowed amounts with actual median allowed amounts, along with 10th and 90th percentile figures, making rate comparisons more precise and actionable than they were in earlier iterations of the rule. CMS has also proposed additional updates that would reduce redundant file sizes and improve the reliability of the underlying data — moving the TiC dataset closer to something that can be used directly in contract preparation without significant normalization work.
In practice, what this means for a provider entering a contract negotiation is concrete: when a payer representative states that your reimbursement rates are in line with the market, you can now respond with specific data showing what that payer reimburses comparable providers in your specialty and geography for the same CPT codes. That is not a general objection — it is a documented, verifiable counterpoint.
The Helix roundtable identified TiC benchmarking as one of the tools providers with improving contract outcomes consistently used to prepare for renewal. The practices that are closing the rate gap are the ones treating TiC data not as a regulatory disclosure to be acknowledged, but as a negotiating asset to be analyzed before every renewal cycle.

There are practical limitations worth noting. The machine-readable files are large, technically complex, and require normalization to make meaningful comparisons across providers and geographies. Extracting the relevant subset — your specialty, your CPT codes, your payer, your market — typically requires either a benchmarking platform or a partner with the tools to parse the data correctly. Raw TiC files are not a plug-and-play negotiation tool. But the information they contain, once structured, is the most direct evidence available of what a payer is actually paying the market and it is information payers have always had and providers have historically lacked.
What to Negotiate Beyond the Rate
The Helix roundtable identified three contract terms that practices consistently underlook when they do reach the negotiating table.
Sustainability means ensuring reimbursement keeps pace with real cost inflation, not just CPI averages. A contract with a 3 percent annual escalator when operating costs are rising at 6 to 8 percent is a contract that loses value by design.
Network alignment means understanding that provider defection is leverage. Marc Genson, a behavioral health executive at Serene Health with 16 years in the field, put it directly at the roundtable: “They have the upper hand. It doesn’t mean they have the only hand. There are going to be providers who aren’t going to contract as much with select payers, regardless of how large they are — if they’ve had a bad experience and something just doesn’t go their way, they’re going to look elsewhere.” When a practice represents a meaningful share of a payer’s network coverage in a specialty or geography, that leverage exists whether or not it is explicitly used. But it has to be acknowledged in the negotiation to have any effect.
Predictability means negotiating the coverage terms, not just the rate. Telehealth carve-outs, session limits, and authorization thresholds are not in the fee schedule. They are in the contract language, and they determine how much of the negotiated rate a practice actually collects. Genson also emphasized building a value case that goes beyond rates: “The more information you can provide to make your practice seem strong and dedicated and loyal to providing those services, the better it can be for everyone — it makes them look at us as a reliable, dedicated informational source that they want their members to go to.” For a detailed look at how to evaluate what is inside a contract before and during negotiation, Neolytix’s guide to payer contracting for providers covers the key components of in-network agreements.
Where to Start in Your Own Contracts
A full benchmarking analysis does not have to start with every payer and every code. The roundtable finding that revenue loss concentrates in specific codes points toward a practical entry point: identify the 20 CPT codes that generate the most revenue across your payer mix, then calculate your percentage of Medicare reimbursement per code, per payer.
That calculation produces a comparison table that shows exactly where each payer sits relative to the federal baseline for the services you perform most. If your highest-volume code is reimbursing at 110 percent of Medicare from your largest commercial payer while the market average for that specialty and region sits at 145 percent, you have a quantifiable, defensible basis for a rate review request. Genson’s framing from the roundtable captures the approach well: “You’re not going to ask for the sun, the moon, and the stars — you’re going to ask for something that’s realistic based on aggregated data.”
Timing matters as much as the data. Inamdar recommended preparing “at a minimum, 3 to 6 months in advance — just getting the presentations ready, materials ready, and what’s the rate request that we’re going to have.” Most payer contracts require 60 to 90 days notice to avoid automatic renewal, so starting 120 days out provides adequate time to build the analysis, prepare the value case, and approach renewal from a position of preparation rather than urgency.
For a step-by-step framework on building that case, including how to use Transparency in Coverage data and MGMA benchmarks alongside CPT-level analysis, Neolytix’s guide to how to negotiate payer contracts using market rate data covers the full process.
Where Payer Reimbursement Rates Are Heading
The Helix roundtable also surfaced a clear directional shift in how payer contract negotiations are evolving, and what practices building their evidence base now stand to gain.
Annual rate reviews are beginning to replace the standard three-year lock-in model, at least for practices with sufficient leverage and data to drive that conversation. Transparency in Coverage benchmarks are becoming standard negotiating tools rather than technical resources available only to sophisticated health systems. And outcome-linked reimbursement — tying rates to metrics like PHQ-9 scores, GAD-7 assessments, and session completion rates — is increasingly on the horizon, particularly in behavioral health.
That last shift carries an important implication. Practices that are already tracking and documenting outcome data have a material advantage at every renewal from 2026 onward. Those that are not have a narrowing window before outcome metrics become a standard component of what payers expect providers to bring to the table.
Providers are also beginning to exit payer relationships that cannot be brought to sustainable terms, gradually shifting network leverage back toward practices with strong quality profiles and concentrated geographic coverage. That shift does not happen overnight, but it is directional — and it favors practices that understand their position in each payer’s network before they sit down to negotiate.
Conclusion
The payer reimbursement rate gap is not primarily a negotiation problem. It is an information problem. Practices that close the gap do so by knowing where they stand relative to the market before they arrive at the table — by code, by payer, by geography — and by treating each renewal cycle as the only opportunity to correct years of accumulated drift.

Frequently Asked Questions
What is a good reimbursement rate from insurance?
There is no universal answer, but the benchmark most commonly used in commercial negotiations is percentage of Medicare. National commercial reimbursement for professional services averages approximately 148 percent of Medicare fee-for-service rates, according to Milliman benchmarking data. What counts as a good rate depends on specialty, geography, and payer — which is why CPT-level benchmarking against local market data is more useful than any single benchmark figure.
Why do payer reimbursement rates vary between providers?
Rate variation between providers billing the same CPT codes to the same payer in the same market is driven primarily by negotiating history. Payers track which practices challenge their rates and which accept initial offers. Providers who have consistently negotiated from market data tend to hold higher rates over time. Practices that have auto-renewed without renegotiation typically see rates drift downward in real terms even when nominal CPI adjustments are applied.
How do I find out if my payer rates are below market?
Start by pulling your top 20 CPT codes by volume and calculating your contracted reimbursement from each payer as a percentage of the Medicare allowed amount for your geographic locality. Then compare those figures against Transparency in Coverage data and specialty benchmarks from MGMA or similar sources. That comparison identifies where the gap is largest and which payer relationships deserve priority attention at renewal.
How often should provider reimbursement rates be renegotiated?
Most payer contracts operate on three-year terms with automatic renewal provisions. The practical answer is: at every renewal cycle, with preparation beginning 3 to 6 months before the renewal date. Annual benchmarking — even in non-renewal years — provides the ongoing baseline needed to catch silent rate erosion and prepares the practice for a faster, stronger renegotiation when the window opens.
What CPT codes are most commonly underpaid by commercial payers?
Underpayment concentrates in high-volume procedure codes rather than any single specialty — the codes a practice bills most frequently are also the ones where below-market rates have the greatest cumulative impact. Evaluation and management codes, high-frequency specialty procedures, and behavioral health session codes are consistently flagged in CPT-level audits. A code-level review of your top 20 billed procedures across your major payer relationships is the most direct way to identify where the exposure is in your specific contract portfolio.
