If you’re new to medical billing or healthcare administration, understanding all the unique terms and codes can feel challenging at first. One key concept that will help you navigate the healthcare industry is the Entity Code. But what is an Entity Code in medical billing, and why is it so vital throughout the claims process?
This helpful guide breaks down Entity Codes in medical billing so you’ll know what they mean, how they work, and why they must be accurate for smooth claims submission and effective medical billing services.
What Is an Entity Code in Medical Billing?
An Entity Code in medical billing is a unique identifier—typically a two- or three-character code—that classifies the type of entity or party connected to a health insurance claim. These codes help everyone involved, from providers to insurance companies, quickly see who or what each part of the claim refers to. Accurate entity codes ensure that the data on medical claims is clear, organized, and easy to understand.
Within the medical billing process, Entity Codes are used to indicate specific roles, such as:
Patient (the individual receiving care)
Provider (the person or practice rendering services)
Insurance companies (payers managing claims and reimbursements)
Here’s a helpful example:
Entity Code "IL": Identifies the insured individual or subscriber (the person whose health insurance covers the claim)
Entity Code "DN": Refers to the referring provider (the healthcare professional who recommended the service)
Using the right codes makes claims submission much more efficient and reduces the risk of confusion or delay. In fact, understanding entity codes has become essential for anyone working in medical billing services, from professionals to those just getting started.
Why Are Entity Codes So Important in the Medical Billing Process?
While they may seem small, Entity Codes play a crucial role in ensuring claims are processed smoothly and accurately in the healthcare industry. Here’s why accurate entity codes are so important:
Reduce the Risk of Errors: Correct codes keep everyone on the same page, helping to reduce common entity code errors that could result in denied or delayed claims.
Support Claims Submission: Properly coded claims move through the claims process faster, with less back-and-forth due to unclear or missing information.
Ensure Compliance: Using the correct entity code supports compliance with industry regulations (such as HIPAA) and helps your organization avoid costly mistakes in medical billing services.
Facilitate Communication: With multiple entities involved in each healthcare claim, clear codes provide a universal language among patients, providers, payers, and others.
Streamline the Medical Billing Process: Modern billing relies on automation—unique identifiers like entity codes help systems quickly sort, match, and validate claims data.
Entities Involved in Medical Billing
It’s helpful to know the main types of entities involved in the medical billing process:
Patient or Subscriber: The person receiving care (may have a health insurance claim number, or HICN).
Dependent: Such as a child or spouse, covered under the same plan.
Billing Provider: The entity billing for services performed.
Rendering Provider: The practitioner actually providing care.
Payer (Insurance Company): Responsible for processing and reimbursing claims.
Other Providers: Entities like referring physicians or facilities.
How Are Entity Codes Used in Claims Submission?
Let’s look at how entity codes appear throughout typical medical billing services:
1. Patient Registration
When a patient first registers, their insurance details—including type of entity and their health insurance claim number (HICN)—are collected and categorized. Entity codes clarify the relationship for each individual:
IL: Insured or subscriber
19: Child dependent
01: Spouse dependent
2. Medical Claims Creation
Accurate entity codes are essential when creating a claim, so each party is clearly identified:
85: Billing provider
82: Rendering provider
3. Claims Submission
During claims submission, the right entity codes make sure that everyone’s role is clear and that the claim is filled out accurately. This is key for insurance companies to process claims promptly in the healthcare industry.
4. Claims Adjudication
Once submitted, insurance companies use these entity codes to review and adjudicate claims, determining eligibility, payment, and compliance.
Overpayments: If an insurance company pays more than owed, recoupment occurs to reclaim the overage.
Post Payment Audits: Audits may uncover discrepancies or noncompliance with proper billing practices.
Fraud Investigations: If a fraudulent or erroneous claim is discovered, recoupment processes begin.
Eligibility Adjustments: Changes or corrections in patient eligibility can prompt a recoupment.
Duplicate Claim Payments: Claims paid more than once are subject to recoupment requests.

What Happens If You Use the Wrong Entity Code in Medical Billing?
Using the wrong or inaccurate entity code in a healthcare claim can cause real issues:
Claim Denials: Incorrect codes are among the most common entity code errors leading to denied claims.
Processing Delays: Claims must be corrected and resubmitted, slowing down the entire claims process.
Lost Revenue: Frequent errors can impact income for healthcare providers and medical billing services.
Helpful Tip:
Always double-check your entity codes before claims submission to ensure your process stays on track and revenue isn’t lost.
Tips for Using Accurate Entity Codes
Understanding and using accurate entity codes is key for anyone involved in the medical billing process:
Use Medical Billing Software: Choose software that lists and updates all relevant codes in the medical billing process.
Reference Official Guidelines: Always consult current industry standards and codebooks to find and confirm the correct entity code.
Get Certified: Consider medical billing and coding certifications to build expertise in the healthcare industry.
Stay Updated: Code sets and healthcare regulations can change, so be sure to keep learning and updating your knowledge base.
Helpful Tip:
If you’re not sure which code to use, don’t guess. Review official resources or ask an experienced colleague—getting it right upfront reduces the risk of errors.
