In short: payer contracting is the work of making sure the rates and terms you signed are the ones you are paid under. We benchmark fee schedules against Medicare, test remittances against the contract, flag costly terms, and support the negotiation with data.
What does a payer contracting service do?
A payer contracting service checks what each insurer actually pays against what your contract says, then supports the talks to fix terms that cost you money. Our work is benchmarking, underpayment detection, negotiation support and contract loading. The payer decides what it will agree to, so we never promise a rate increase.
A contract is only worth what gets paid under it. We read the rates and the rules around them (filing limits, appeal windows, escalators, carve-outs) together.
How do you review a fee schedule against Medicare rates?
We compare each contracted rate with what the Medicare Physician Fee Schedule pays for the same code in your area. The Medicare Physician Fee Schedule (MPFS) is the list CMS uses to price physician and other professional services. Comparing each contracted rate with it gives you one common yardstick across payers.
CMS publishes a free PFS Look-up Tool for this. According to CMS, you can search by a single procedure code, a range of codes or a list of codes, and you can search national payment amounts or amounts for a specific MAC or MAC locality. The tool covers more than 10,000 services.
The tool has limits you should know before you build a benchmark on it. CMS states that it does not display codes priced by the Medicare Administrative Contractor (MAC) or Medicare Part B non-payable codes. For those codes the benchmark needs another source, or a different method.
CMS also publishes the PFS relative value files, a national payment amount file and a locality configuration file. We use the published files to confirm the Medicare rate for each code you bill most.
Which contract terms should you check besides the rates?
Four kinds of terms move your revenue as much as the rate does: timely filing, appeal windows, rate escalators and carve-outs. Every number in these terms comes from your own contract, so we read the signed document and each amendment rather than rely on a payer's general manual.
| Term | What it controls | What we check |
|---|---|---|
| Timely filing | How long you have to submit a claim before the payer can deny it | The number of days, what date starts the clock, and whether corrected claims restart it |
| Appeal window | How long you have to dispute a denial or an underpayment | The day count, the required format, and how many levels the contract allows |
| Rate escalator | Whether rates rise on a set schedule during the term | Whether an escalator exists, the date it applies, and whether payers load it on time |
| Carve-out | A service paid on a different basis than the main fee schedule | Which codes or revenue codes are carved out, and what rate or method applies instead |
| Term and renewal | How long the contract runs and how it renews | Notice dates for renegotiation or termination, and any automatic renewal |
For a benchmark on timely filing, Medicare's own rule is public. Under 42 CFR 424.44(a)(1), a Medicare claim must be filed no later than the close of the period ending 1 calendar year after the date of service, unless an exception applies. A commercial contract sets its own limit, so use the number in your signed agreement. Our timely filing calculator helps you work out a deadline once you know your contract's number.
Late-filing denials and missed appeal windows are revenue lost to a contract term. We pass those patterns to denial management so the problem is fixed on the billing side too.
How do we find out if we are being paid below contracted rates?
Compare the allowed amount on each remittance with the rate in your contract for the same code. An allowed amount is the most a plan will pay for a covered service. When it is lower than the contracted rate, you have an underpayment, and the gap times your volume is the money at stake.
The comparison runs on electronic remittance advice (ERA) data, the X12 835 file your payers send. Each line carries the amounts and adjustments for a claim. A contractual adjustment is the part you write off because of the contract, and it is where an incorrect fee schedule hides: the payer takes a bigger write-off than the contract allows.
We cover the method in more depth in our guide on how to find payer underpayments against your contract. The finished disputes feed into A/R recovery.
A contract says code 99285 pays a set amount. The remittances for one month show the payer allowed less on 40 claims. The difference is the same on every line, which points to a fee schedule loaded wrong, not to 40 separate errors. One correction request covers all 40.
What data do you need to benchmark our rates?
We need your signed contracts and fee schedules, plus 12 or more months of claims and remittance data if you have it. The contract tells us what should have been paid and the remittances tell us what was paid. Without both, a benchmark is only a guess.
- Signed contracts, all amendments and every fee schedule exhibit
- Claims by payer, code, date of service and billed amount
- ERA or remittance data showing allowed and paid amounts
- A list of the payers you are in network with, and the effective date for each
- Your top codes by volume, if your system can produce them
We keep it under the Business Associate Agreement we sign with every client.
How does payer contracting interact with out-of-network pricing power under the NSA?
The No Surprises Act links out-of-network payment to in-network contract rates through the qualifying payment amount (QPA). The QPA is generally the plan's median contracted rate for the same or similar service in your geographic region. So what the plan pays other providers like you in your region feeds the benchmark it points to in a dispute with you.
The rule sits in 45 CFR 149.140. It defines the median contracted rate by arranging the contracted rates in order from least to greatest and selecting the middle number. The rates counted are those for the same or similar item or service, from a provider in the same or similar specialty or facility type, in the same insurance market and geographic region. A single case agreement or letter of agreement does not count as a contract for this purpose.
In federal IDR, 45 CFR 149.510 requires the certified IDR entity to consider the QPA. It also requires the entity to consider information from the parties, including good faith efforts to enter network agreements and, where relevant, the contracted rates between the parties during the previous 4 plan years. The entity must not consider usual and customary charges, or the rates public payors such as Medicare pay.
That makes the history of your contracts relevant to a dispute. We do not repeat the rules here. The QPA page explains how it is calculated and disclosed, and the federal IDR process page covers the steps. For the dispute work itself, see out-of-network billing and IDR.
For groups choosing between in-network and out-of-network status with a payer, our guide on out-of-network strategy for ER groups sets out the trade-offs. We put numbers behind the decision; the choice is yours.
When should a hospital or group renegotiate a payer contract?
Renegotiate when the data shows a payer pays well below your other payers for the same codes, or when your contract's notice dates open a window to do so. Both signals come from the same review. The notice date in your contract decides when you can ask, so we put that date on the calendar.
- A benchmark shows one payer far below your other payers on your highest-volume codes
- The contract is near its renewal or notice date
- You add a location, a service line or a freestanding emergency department
- Underpayment variances keep repeating after correction
The decision to stay in network, go out of network or end a contract belongs to you. Leaving a network changes how claims are paid and what disputes you face, so we model the effect with your own claims data before you decide. We do not rank payers or predict an outcome.
For a new location, we coordinate the contract request with our credentialing and enrollment team, so the contract request and the enrollment move together.
How we handle payer contracting at Nucleus Align
We work from your contracts and your remittances, and we report in plain tables. You get the benchmark, the list of terms we recommend raising, and the underpayments we found. We support the negotiation by preparing the data and the written case. No payer is bound to agree to anything we raise.
The work is built for hospitals, emergency departments and freestanding ERs, urgent care networks and large groups. It sits next to revenue cycle management, so what we learn in contracting goes straight to claim submission and denial work. Pricing for our billing services is on the pricing page.
To see whether a contract review makes sense for your organization, book a call. Bring one contract and a month of remittances, and we will tell you what we would check first.

Who we do this for
Common questions
Straight answers from the team that does the work.
Ask a billing lead directly. A 20-minute call, Monday to Friday, 9am to 5pm Eastern.
01What does a payer contracting service do?
It checks what a payer pays against your contract and supports talks to fix costly terms. At Nucleus Align that means benchmarking rates, finding underpayments, preparing negotiation support and loading fee schedules. The payer decides whether to agree to any change, so we never promise rate increases.
02When should a hospital or group renegotiate a payer contract?
Renegotiate when your data shows a payer paying well below your other payers on the same codes, when a renewal or notice date opens a window, or when you add a location or service line. The notice date in your own contract decides when you can ask, so we calendar it.
03How do we find out if we are being paid below contracted rates?
Compare the allowed amount on each remittance line with the contracted rate for the same code. A difference means an underpayment. We load your fee schedule into a reference table, test every ERA line against it, group the variances and dispute them with the contract page attached.
04How does payer contracting interact with out-of-network pricing power under the NSA?
Under 45 CFR 149.140, the QPA is built from a plan's median contracted rates for similar services in your region. In IDR, 45 CFR 149.510 requires the entity to consider the QPA and, where relevant, contracted rates between the parties over the previous 4 plan years.
05What data do you need to benchmark our rates?
We need signed contracts, amendments and fee schedule exhibits, plus claims and remittance data by payer, code and date of service. Twelve or more months is best. We also want your list of in-network payers with effective dates, so we know which contract applies to each claim.
06How do we negotiate annual escalators and timely filing terms?
First read what the signed contract already says, because the escalator and the filing limit are specific to each agreement. Then we show the payer the cost of the current term with your own claims data. We support the request with that evidence; the payer decides whether to change it.
07Do you handle contract loading and fee schedule verification?
Yes. We enter each fee schedule by code and effective date, then test remittances against it so a wrong load shows up as a pattern. Verification means comparing what the payer paid with the contract rate, line by line, and flagging variances for correction or dispute.
08Can you negotiate for a new freestanding ER or urgent care location?
We can prepare the data and written request for a new location and support the talks. The payer decides whether and when to add it, and we work alongside our credentialing team so the contract request and enrollment move together.
09What contract terms cause the most denials?
We cannot rank terms across all payers. In a contract review we check the terms that most often decide whether a claim is paid: timely filing limits, appeal windows, authorization requirements and carve-outs for specific services. Each is specific to your agreement, so we read the signed text.
10Is payer contracting priced separately from billing?
Billing pricing and credentialing pricing are on our pricing page. For contract review work, scope depends on the number of payers and contracts involved, so we confirm it on a call before any work starts. Use the book a call link to start that conversation.
