What Is Contractual Adjustment in Medical Billing

If you have ever received a medical bill, you may have noticed a line item for “contractual adjustment.” This term can be confusing for patients who are not familiar with the medical billing process. In this article, we will explain what contractual adjustment is in medical billing and how it can impact your healthcare expenses.

What is Contractual Adjustment?

A contractual adjustment is a reduction in the amount a healthcare provider bills a patient or an insurance company. It is a negotiated amount that the provider agrees to accept as payment for their services, usually in a contract with an insurance company or government program like Medicare or Medicaid.

The amount of a contractual adjustment varies depending on the contract negotiated between the provider and the payer. For example, if a provider charges $1,000 for a procedure, but their contract with an insurance company sets the price at $700, the $300 difference is a contractual adjustment.

Who is Impacted by Contractual Adjustment?

Contractual adjustments primarily impact patients who have health insurance. Providers negotiate contracts with insurance companies or government programs like Medicare and Medicaid, agreeing to accept a certain amount of payment for their services. This negotiated rate is often lower than the amount the provider would charge an uninsured patient.

If you have health insurance, you may see contractual adjustments on your medical bills. The amount of the adjustment depends on your insurance plan, as well as the specific contract negotiated between your provider and your insurance company.

How Does Contractual Adjustment Impact Healthcare Costs?

Contractual adjustment can impact healthcare costs in several ways. First, it can lower the out-of-pocket expenses for patients who have insurance. If a provider bills $1,000 for a procedure but agrees to a contractual adjustment of $300, the insurance company will only pay $700, and the patient will only be responsible for their co-pay or deductible, which will be based on the $700 amount.

However, contractual adjustments can also lead to higher healthcare costs for uninsured or underinsured patients. Because providers negotiate lower rates with insurance companies, they often charge higher rates to patients who do not have insurance, leading to higher medical bills.

In addition, contractual adjustments can impact the overall cost of healthcare. Insurance companies negotiate lower rates with providers to keep costs down for their customers. However, this can lead to providers charging more to uninsured patients to make up for the lower rates.


Contractual adjustment is a term that patients may see on their medical bills. It is a negotiated amount that a healthcare provider agrees to accept as payment for their services. Contractual adjustments primarily impact patients who have health insurance, as providers negotiate contracts with insurance companies, government programs, or other payers. While contractual adjustments can lower healthcare costs for patients with insurance, they can lead to higher expenses for uninsured or underinsured patients and impact the overall cost of healthcare.
