What Usual, Customary, and Reasonable Means for Medical Bills

UCR means usual, customary, and reasonable: the typical amount charged for a medical service in a geographic area, based on what providers there usually charge for the same or similar service. Health plans use UCR to decide how much of a bill they’ll cover. Personal injury firms use it to show that a client’s medical bills are reasonable and to negotiate liens down to a fair amount. (In trucking and crime statistics, UCR stands for other things. This guide covers medical billing.)

A UCR analysis is one step in calculating economic damages, because it tests the medical expense line before an adjuster or a jury does. EvenUp gathers the inputs for that test, from itemized bills to payments and adjustments, so the analysis starts from a complete record.

UCR at a Glance

1. UCR is the typical charge for a medical service in a geographic area.
2. UCR amounts are set per CPT or HCPCS code and per area, usually as a percentile of charges.
3. FAIR Health’s free consumer tool, its licensed benchmarks and the Medicare fee schedule are the main ways to find rates.
4. Whether a PI claimant can recover billed charges or only paid amounts depends on state law.
5. A line-by-line UCR analysis supports the demand and gives the firm leverage to reduce liens.

What Does Usual, Customary, and Reasonable Mean for Medical Bills?

For medical bills, usual, customary, and reasonable means the amount that’s typical for a service where it was performed. HealthCare.gov defines UCR as the amount paid for a medical service in a geographic area, based on what providers in the area usually charge, and notes that insurers sometimes use it to set the allowed amount.

Each word does a job:

1. Usual: what this provider normally charges for the service.
2. Customary: the range other providers in the same area charge for it.
3. Reasonable: a charge that fits both, or that unusual circumstances in the case justify.

A medical bill can show three different numbers for the same service. Keep them apart, because each plays a different role:

Number	What It Is	Where It Shows Up
Billed charge	The provider’s full price	Itemized bills and lien statements
Paid or allowed amount	What a health plan or payer actually paid or agreed to pay	Explanation of benefits (EOB) and payment ledgers
UCR amount	The typical charge or payment for that code in that area	Benchmark databases and plan documents

When a provider is out of network, a plan may pay only up to its UCR amount, and the patient can be billed for the difference.

How Are Usual and Customary Charges Set for CPT Codes?

Usual and customary charges are set code by code. Each service on a bill carries a CPT or HCPCS code, and the UCR amount for that code depends on where the service was performed.

Benchmark databases collect billed charges for each code in each area and sort them into percentiles. A plan then picks the percentile it’ll treat as usual and customary, which is why two plans can set different UCR amounts for the same CPT code in the same city.

A widely used independent source is FAIR Health, a nonprofit created in 2009 under a settlement of a New York State investigation into conflicts of interest in how health insurance claims were priced. Its database holds billions of privately billed medical and dental claims, arrayed into percentiles for each procedure code and geographic area, which it calls a geozip. It publishes charge benchmarks, built from non-discounted billed charges, and allowed benchmarks, built from negotiated in-network amounts.

Medicare works differently. It pays from a fixed Physician Fee Schedule by code and locality, and those rates serve as a common reference point in UCR comparisons.

How to Find Usual and Customary Rates

There are five practical ways to find usual and customary rates for a medical service:

1. FAIR Health Consumer. The free cost lookup tool shows in-network and out-of-network cost estimates for medical and dental procedures by area. It’s the quickest check for a single service, though it doesn’t apply to Medicare, Medicaid or Tricare.
2. FAIR Health licensed benchmarks. Firms, billing experts and plans license the full percentile data by CPT code and geozip. Use these when the numbers need to hold up in a dispute.
3. The Medicare fee schedule. The CMS Physician Fee Schedule Look-up Tool shows Medicare payment amounts by code, nationally or by locality.
4. The explanation of benefits and plan documents. The EOB shows the allowed amount the plan applied, and the plan documents say how it sets UCR for out-of-network care.
5. State rules. Some states set the measure by statute. Florida, for example, ties some medical damages evidence to multiples of Medicare and Medicaid rates.

Whatever the source, match the code, the area and the year the service was performed.

Why Does UCR Matter in Personal Injury Cases?

UCR does three jobs in a PI case:

1. Defending specials. When the defense argues the bills are inflated, a line-by-line comparison to area benchmarks shows which charges are typical and which need support.
2. Knowing what the demand can claim. States set different rules on whether a claimant recovers billed charges or only paid amounts, and some set their own formula.
3. Negotiating liens and reimbursement. Providers treating under a letter of protection and health plans seeking reimbursement start from their own numbers. A UCR analysis shows where those numbers sit against the market.

The rules on billed versus paid amounts vary widely, so the analysis has to fit the venue. Three examples show the range:

1. California: In Howell v. Hamilton Meats & Provisions (2011), the California Supreme Court held that a privately insured plaintiff can recover past medical expenses only up to the amounts paid or still owed. The unpaid balance of the billed charges isn’t recoverable.
2. Texas: Civil Practice and Remedies Code § 41.0105 limits recovery to amounts “actually paid or incurred,” and in Haygood v. De Escabedo (2011) the Texas Supreme Court held that only evidence of recoverable expenses is admissible.
3. Florida: Section 768.0427, added in 2023, limits evidence to amounts paid for paid bills. For claimants with no coverage, it allows evidence of 120% of the Medicare rate, or 170% of the state Medicaid rate when no Medicare rate applies. Treatment under a letter of protection also requires itemized bills coded by CPT, ICD or similar code sets.

How to Conduct a UCR Analysis on PI Medical Bills

Work line by line. A total-to-total comparison hides the charges that matter.

1. Get itemized bills. Request bills that show each service by CPT or HCPCS code, date of service and charge, such as CMS-1500 and UB-04 forms. Summary balances can’t be benchmarked.
2. Match each line to a diagnosis and a date. Pair every CPT line with the ICD-10 diagnosis it treated and the date of service.
3. Choose the benchmark that fits the venue. Use charge benchmarks where billed amounts are admissible, paid or allowed benchmarks where they aren’t and any statutory formula the state sets.
4. Pull the usual and customary rate for each CPT code. Look up each code for the provider’s geozip or Medicare locality, using data from the year the service was performed.
5. Compare and flag outliers. Record the billed amount, the benchmark and the ratio between them for each line. Flag lines well above the percentile you chose.
6. Document the method. Note the source, percentile, geography and data year for every line. An analysis the other side can’t trace is easy to attack, and an expert may need to stand behind it.
7. Apply it to the case. Adjust the specials to what the jurisdiction allows, and carry the flagged lines into lien and reimbursement negotiations.

How Do You Use UCR to Negotiate Liens and Reimbursement?

The analysis that defends the specials also gives the firm leverage on the back end.

1. Provider liens and letters of protection. When a provider’s lien sits well above the area benchmark for the same codes, the comparison supports a request to reduce it. Bring the line-by-line table so the requested reduction has a basis.
2. Health-plan reimbursement claims. Plans usually paid an allowed amount below the billed charge. Confirm the plan’s claim matches what it actually paid, line by line, before negotiating the reduction its plan terms allow.
3. Government payers. Medicare and Medicaid recovery claims follow federal and state rules, so a UCR argument carries less weight there. Check the payer’s own process for reductions and waivers.

Lien resolution is where the work ends, and where clients feel the result in their net recovery. EvenUp’s Pre-Litigation as a Service (PLAAS) includes lien resolution and negotiation as a stage of the case.

Common UCR Mistakes

1. Benchmarking a summary bill. Without codes and dates, there’s nothing to compare.
2. Using the wrong geography. A national average undercuts a charge that’s normal in a high-cost metro area.
3. Using the wrong year. Price each service against data from the year it was performed.
4. Picking a benchmark the venue won’t accept. A Medicare comparison may help in Florida and hurt the claim elsewhere.
5. Skipping the documentation. A conclusion without the source, percentile and data year behind it won’t survive a challenge.

Where EvenUp Fits

A UCR analysis is only as good as the bills under it. EvenUp gathers and organizes those inputs so the analysis starts from a complete record.

Medical Management keeps a care timeline for every case that shows total treatment costs and upcoming medical expenses against policy limits, and it flags missing bills and records while there’s still time to request them.

EvenUp’s balance verification agent calls providers for total charges, payments and adjustments, collections, liens and reductions, and it requests an updated statement. Those are the numbers a UCR comparison and a lien negotiation depend on. The lien balance verification agent confirms current lien balances and flags pending or disputed amounts.

When the specials are set, Express Demands, part of AI Drafts, presents them in the demand with each figure traced to the bills in the file. The demand amount is always the firm’s decision. For the full drafting process, see how to write a personal injury demand letter.

Price Every Line Before the Adjuster Does

Adjusters and defense counsel test medical bills one line at a time. A firm that has already priced each line against the usual and customary rate for its area, under the rules of its venue, walks into that conversation with the answer. The same work then cuts liens down to size, so more of the recovery reaches the client.
