How Does The Insurance Company Determine What’s Covered Under ‘reasonable’ Or ‘customary’ Costs?

Have you ever wondered how your insurance company determines what expenses are considered ‘reasonable’ or ‘customary’? It seems like every time you receive a medical bill, there’s always some sort of discrepancy between what the doctor charges and what your insurance is willing to cover. It can be frustrating and confusing, but understanding how these decisions are made can help alleviate some of the stress. In this article, we’ll dive into the world of insurance and explore how they determine what’s covered under ‘reasonable’ or ‘customary’ costs. By the end, you’ll have a better understanding of the process and be able to navigate your insurance coverage more effectively. So let’s get started!

Insurance companies often rely on a database called the ‘Usual, Customary, and Reasonable’ (UCR) fees to determine what they consider an appropriate amount to pay for medical services. This database is constantly updated and provides a range of fees that are accepted as fair and reasonable in a specific area. The insurance company will compare the cost of the service you received to this range and determine whether it falls within the ‘reasonable’ or ‘customary’ range. If it does, they will typically cover a certain percentage of the cost, leaving you responsible for the remainder.

But what about those times when the cost of your medical service exceeds the ‘reasonable’ or ‘customary’ range? Well, that’s where things can get a bit tricky. In some cases, the insurance company may still provide coverage, but at a reduced percentage, leaving you with a higher out-of-pocket expense. In other cases, they may deny coverage altogether. It’s important to remember that insurance companies are businesses, and they are often trying to strike a balance between providing coverage and managing costs.

In conclusion, understanding how insurance companies determine what’s covered under ‘reasonable’ or ‘customary’ costs can help you navigate the complexities of your coverage. By relying on the UCR fees database and considering various factors such as location and provider, insurance companies make decisions about what they will and will not cover. While it may not always seem fair, being knowledgeable about this process can empower you to advocate for yourself and make informed decisions about your healthcare. So the next time you receive a medical bill, take a closer look at the details and remember that there is a method behind the insurance company’s madness.

How Does The Insurance Company Determine Whats Covered Under reasonable Or customary Costs?

Understanding Insurance Coverage Determinations

When it comes to health insurance, understanding what is covered and what is not can often feel like navigating a maze. Insurance companies use various factors to determine coverage, including what they deem as ‘reasonable’ or ‘customary’ costs. In this article, we will delve into the definition of these terms, the factors considered by insurance companies, and the role of insurance policy in determining coverage.

Defining ‘Reasonable’ and ‘Customary’ Costs

Meaning of ‘reasonable’ costs

‘Reasonable’ costs refer to the amount that an average person would pay for a particular service or treatment under normal circumstances. Insurance companies consider the prevailing market rates for similar services in a specific geographic area when determining what is reasonable. This ensures that you are not being charged excessively for a covered service.

Interpreting ‘customary’ costs

‘Customary’ costs, on the other hand, represent the range of charges for a specific service within a given geographic area. Insurance companies determine these costs by analyzing the charges submitted by healthcare providers and identifying the range where the majority of charges fall. This ensures that the cost of a service is within the acceptable range, avoiding overcharging or undercharging.

How ‘reasonable’ and ‘customary’ are determined

To determine ‘reasonable’ and ‘customary’ costs, insurance companies collect data on the charges submitted by healthcare providers during a specific time period. By analyzing this data, they establish the average and range of charges for different services in a particular area. It is important to note that ‘reasonable’ and ‘customary’ costs may vary depending on your geographic location and the specific provider you choose.

Factors Considered by Insurance Companies

When determining coverage, insurance companies take various factors into account. These factors can greatly influence what services and treatments are considered ‘reasonable’ or ‘customary’ under your policy. Let’s explore some of these factors.

Geographic location

The cost of healthcare services can vary significantly based on your geographic location. Some areas may have higher costs of living or limited provider options, which can impact the ‘reasonable’ or ‘customary’ costs. Insurance companies consider this geographic influence to ensure that their coverage aligns with the prevailing market rates in a specific area.

Provider networks

Insurance companies often have contracts with specific networks of healthcare providers. The rates negotiated with these in-network providers are generally lower than those with out-of-network providers. As a result, the ‘reasonable’ and ‘customary’ costs are often determined based on the charges of in-network providers. Seeking treatment from an out-of-network provider may result in higher out-of-pocket expenses or limited coverage.

Services and treatments

Insurance companies evaluate the types of services and treatments being requested to determine if they are covered under your policy. Some policies may have specific exclusions or limitations on certain services, such as elective cosmetic procedures or experimental treatments. Insurance companies base their coverage decisions on medical necessity, evidence-based treatments, and the terms outlined in your policy.

Medical codes and billing practices

To facilitate streamlined billing and accurate reimbursement, healthcare providers use standardized medical codes for reporting services and procedures. Insurance companies rely on these coding systems to assess the ‘reasonable’ and ‘customary’ costs associated with different medical services. They also establish billing guidelines and reimbursement rates based on these codes.

Geographic Influence on Costs

The geographic location plays a pivotal role in determining healthcare costs and consequently affects what insurance companies consider ‘reasonable’ or ‘customary.’ Let’s explore some aspects of geographic influence on costs.

Regional cost variations

Different regions have varying costs associated with healthcare services and treatments. Factors such as the cost of living, local market dynamics, and supply and demand for providers contribute to these cost variations. Insurance companies take into account these regional differences to ensure their coverage aligns with the prevailing rates in each area.

Cost of living affecting prices

Areas with a higher cost of living often result in increased healthcare costs. Higher rents, employee wages, and operating expenses can drive up the overall cost of healthcare services in these regions. Insurance companies consider these cost of living factors when determining the ‘reasonable’ and ‘customary’ charges for services in a particular area.

Availability of providers in the area

The number of healthcare providers in a specific region can impact the cost of services. Areas with limited providers may have higher costs due to increased demand and limited competition. Conversely, regions with an abundance of providers may have lower costs as competition drives prices down. Insurance companies take into consideration the availability of providers when establishing the ‘reasonable’ and ‘customary’ costs.

Provider Networks and Coverage

Understanding how insurance companies work with provider networks is essential in comprehending coverage determinations. Let’s explore the key points related to provider networks and coverage.

In-network vs. out-of-network providers

Insurance companies often establish contracts with specific networks of healthcare providers. Seeking treatment from an in-network provider typically results in lower out-of-pocket costs, as the negotiated rates are generally lower. In contrast, using an out-of-network provider may result in higher expenses, limited coverage, or the need to meet higher deductibles or coinsurance rates.

Contracted rates with in-network providers

Insurance companies negotiate contracted rates with their in-network providers. These rates are pre-negotiated and agreed upon by both parties to ensure affordable and consistent access to healthcare. When determining coverage, insurance companies often refer to these contracted rates as the baseline for assessing ‘reasonable’ and ‘customary’ costs. The difference between the provider’s charge and the contracted rate may be patient responsibility, such as a copayment or coinsurance.

Limits on out-of-network coverage

While most insurance policies provide coverage for out-of-network providers, there are often limitations in place. These limitations can include higher deductibles, higher coinsurance rates, or coverage being limited to certain circumstances, such as emergencies or referrals from in-network providers. It is crucial to review your policy to understand the extent of coverage for out-of-network providers to avoid unexpected expenses.

Types of Services and Treatments

Insurance coverage varies depending on the types of services and treatments being sought. Understanding the distinctions between covered and non-covered services is crucial in comprehending coverage determinations.

Covered vs. non-covered services

Insurance policies typically specify the services and treatments they cover. Covered services may include routine preventive care, diagnostic tests, hospital stays, and prescription drugs, among others. Non-covered services include those considered elective, cosmetic procedures, or treatments that are not supported by evidence-based medicine. It is essential to review your policy and understand what services are included in your coverage.

Medical necessity

Insurance companies evaluate the medical necessity of services and treatments when determining coverage. Medical necessity refers to services or treatments that are required to treat a specific condition or illness. Insurance policies typically cover services that are medically necessary, while treatments deemed unnecessary may be denied coverage. Your healthcare provider often plays a role in determining medical necessity and providing documentation to support coverage determinations.

Evidence-based treatments

Insurance companies rely on evidence-based medicine when considering coverage for certain treatments. Evidence-based medicine involves using current research, clinical guidelines, and expert consensus to guide treatment decisions. Insurance companies consider the effectiveness, safety, and cost-effectiveness of treatments when evaluating their coverage. Understanding the evidence behind the treatments you seek can help you navigate coverage determinations.

Medical Codes and Billing Practices

Behind the scenes, medical codes and billing practices play a crucial role in coverage determinations. Familiarizing yourself with these aspects can help you understand how insurance companies determine ‘reasonable’ or ‘customary’ costs.

Coding systems and standards

Healthcare providers use standardized coding systems, such as Current Procedural Terminology (CPT) codes, to accurately describe the services and procedures rendered to patients. These codes assist in communication between healthcare providers, insurance companies, and other entities involved in the billing process. Insurance companies use these codes to assess and determine ‘reasonable’ or ‘customary’ charges for covered services.

Billing guidelines

Insurance companies establish billing guidelines that outline the documentation, coding, and submission requirements for service reimbursement. These guidelines ensure consistency and accuracy in billing practices, helping insurance companies determine the coverage for specific services. By adhering to billing guidelines, healthcare providers can help facilitate proper reimbursement and minimize complications in coverage determinations.

Reimbursement rates

Insurance companies determine reimbursement rates, which reflect the percentages or amounts that providers will be paid for covered services. These rates are often based on negotiated contracts between insurance companies and healthcare providers. Reimbursement rates may vary depending on the type of service, the provider’s specialty, geographic region, and whether the provider is in-network or out-of-network. Understanding these rates can help you estimate your out-of-pocket costs for covered services.

Role of Insurance Policy Terms

In addition to the factors discussed above, insurance policy terms greatly influence coverage determinations. It is important to familiarize yourself with your policy terms to understand what is covered and what is not.

Coverage limitations and exclusions

Insurance policies may have coverage limitations or exclusions that impact what services and treatments are covered. These limitations and exclusions can include specific medical conditions, non-covered services, or certain treatments that require pre-authorization. Reviewing your policy’s terms and conditions will provide insight into any limitations or exclusions that may affect your coverage.

Pre-authorization and pre-certification

Certain services or treatments may require pre-authorization or pre-certification from your insurance company. This means obtaining approval from your insurer before receiving the service or treatment. Pre-authorization ensures that the proposed service is medically necessary and meets specific criteria outlined in your policy. Failing to obtain pre-authorization when required can result in denied claims and potential out-of-pocket expenses.

Negotiated rates and fee schedules

Insurance companies negotiate rates with healthcare providers to establish the fees for covered services. These negotiated rates are often lower than the provider’s actual charge and serve as the baseline for determining ‘reasonable’ or ‘customary’ costs. Understanding the negotiated rates or fee schedules associated with your policy can help estimate your out-of-pocket expenses for covered services.

Appealing Coverage Determinations

If you believe that your insurance company has made an incorrect coverage determination, you have the right to appeal their decision. Here are some key points to keep in mind when appealing coverage determinations:

Understanding the appeals process

Each insurance company has an appeals process that outlines the steps you need to take to contest a coverage determination. Familiarize yourself with this process and ensure that you adhere to the specified timelines and requirements. Pay attention to any documentation or supporting evidence you may need to provide during the appeals process.

Submitting additional supporting documents

When appealing a coverage determination, you have the opportunity to submit additional supporting documents. These documents can include medical records, letters from healthcare providers, or any other evidence that supports your case. Make sure to gather all the necessary documents and present a clear and compelling argument for why the coverage determination should be reconsidered.

Review by independent third-party

In some cases, insurance companies may enlist the help of independent third-party reviewers to assess coverage determinations. These reviewers evaluate the medical necessity of the services or treatments in question based on established guidelines and standards. The review process ensures an impartial assessment of the coverage determination, providing you with a fair opportunity to appeal.


Understanding how insurance companies determine what is covered under ‘reasonable’ or ‘customary’ costs is crucial for navigating the complex world of health insurance. Factors such as geographic location, provider networks, services and treatments, and insurance policy terms all play a role in these determinations. By seeking clarity from your insurance provider, reviewing your policy terms, and understanding the appeals process, you can better comprehend coverage determinations and make informed decisions regarding your healthcare. Remember, being knowledgeable about your coverage can greatly impact your out-of-pocket costs and the overall value you receive from your insurance policy.
