What is an Entity Code in Medical Billing?

What is an entity code in medical billing? What happens if you get it wrong? If you’re a mental health or addiction treatment provider, you’ve almost certainly encountered this more than once: you complete insurance paperwork for a session, check it twice, and are confident that everything is ready to go. But, you and your client still get a letter saying the claim has been denied. As a leading revenue management company focused exclusively on the behavioral health industry, Hansei Solutions is here to help. 

Key Points: 

  • In medical billing, an entity code is necessary for accurately indicating the role of an individual or organization involved in a claim. For example, an entity code might identify the policyholder, patient, or healthcare professional. 
  • Proper entity codes are essential for directing payments and reducing denied insurance claims. If an entity code is incorrect, it can lead to payment delays and other challenges for healthcare providers. 
  • Outsourcing your medical billing needs to Hansei Solutions can help you avoid issues like incorrect entity codes, ensuring that you get paid on time while taking administrative burdens off your plate. 

What is an Entity Code in Medical Billing?

What is an entity code in medical billing? An entity code is a two-character code used to identify the role of a person or organization involved in a claim. For example, a policyholder, a patient, or the healthcare professional (e.g., a therapist or psychiatrist) who is providing a service. Getting an entity code right matters because it is critical for directing payments and reducing claim denials. When an entity code is incorrect, it can lead to challenges like payment delays for providers. As you likely know firsthand, this is a problem that providers run into all the time, and it can be incredibly stressful. Correcting it is a process that takes time: it creates more paperwork for you as a professional, which can add even more burden.

FAQs

What does it mean when a claim is rejected for an entity code?

When a claim is rejected for an entity code, it means that the insurance payer or clearinghouse can’t process a claim because the information identifying a participant (e.g., the patient, provider, or billing entity) is invalid, missing, or does not match their records. When this happens, the claim is stopped before it’s officially processed for payment. Unfortunately, this can cause a delay in payments for treatment professionals. 

What does denial ‘this code requires use of an entity code’ mean?

If you get a denial saying ‘this code requires use of an entity code,’ it means that an entity code was either missing, inaccurate, or mismatched. The result of this is that the system can’t process the claim because it does not know which entity is associated with the service. This can happen for many reasons. For example, the code you put in might have been outdated or incorrect. Or, you could have missed a specifier required to identify the type of healthcare plan.

Have insurance denials increased in recent years?

Yes. 2025 statistics indicate that insurance denials have increased in the United States in recent years. Additionally, 68 percent of providers say that submitting clean claims is more challenging than it was a year ago. This has a serious impact on behavioral health providers and those in their care, often causing a great deal of stress and extra paperwork. 

What is the most common reason for insurance denials?

Missing or inaccurate claim data is one of the most common reasons for insurance denials. For example, incorrect or missing entity codes. Outsourcing billing tasks to Hansei means that you can leave it up to our specialists. 

What is NPI in medical billing?

In medical billing, NPI stands for ‘National Provider Identifier.’

How do I fix a rejected entity code in medical billing?

To fix a rejected entity code, you must correct, update, or add the identifying details of the entity that the payer or clearing deems mismatched, invalid, or missing.
