Where Is the Entity Code on the UB-04 Form?

The UB-04 form is a standardized claim document used by institutional providers across the United States, including hospitals and clinics. It transmits detailed service information to insurance payers like Medicare, Medicaid, and commercial insurers for reimbursement. This uniform format streamlines healthcare billing and claims adjudication. Accurate completion of the UB-04 form is important for efficient financial operations and timely payment.

Locating the Entity Code on the UB-04 Form

The entity code on the UB-04 form is found within Field Locator 4 (FL 4), labeled “Type of Bill.” This field is situated near the top left portion of the form, below the provider’s billing information and above the patient details.

FL 4 consists of a three-digit alphanumeric code. The entity code is the first digit of this three-digit “Type of Bill” code. For instance, if the “Type of Bill” in FL 4 is “131,” the entity code is “1.” This initial digit identifies the type of facility submitting the claim.

Understanding the Entity Code

The entity code identifies the type of facility or entity submitting the medical claim. This single digit communicates whether the bill originates from a hospital, a skilled nursing facility, a home health agency, or another institutional provider. For example, a “1” indicates a hospital, while a “2” represents a skilled nursing facility. This categorization is important for payers to properly process claims.

The entity code informs the payer about the nature of the provider and the services being billed, which directly impacts how the claim is evaluated. It helps payers apply the correct reimbursement rules, coverage policies, and claim validation processes specific to that type of healthcare setting. An incorrect entity code can lead to claim rejections or processing delays, as the payer’s system will not recognize the provider type as matching the services claimed. This code guides the entire claims adjudication process.

Determining the Correct Entity Code

Selecting the appropriate entity code for the UB-04 form depends on the type of facility providing services. Providers must accurately identify their organizational classification for correct billing. For instance, a general acute care hospital uses “1” as its entity code. A skilled nursing facility, providing post-acute care, uses “2,” while a home health agency providing in-home care uses “3.” Other common entity codes include “4” for a Religious Nonmedical Health Care Institution, “5” for a psychiatric hospital, and “6” for an Intermediate Care Facility for Individuals with Intellectual Disabilities.

Specific criteria, such as licensing and primary services, determine which code applies. Billing professionals must consult official guidelines, such as the Medicare Claims Processing Manual from the Centers for Medicare & Medicaid Services (CMS), to verify their facility’s classification. This ensures compliance with federal regulations and payer-specific requirements.

A facility’s designation, often outlined in its operating license, dictates the correct entity code. For example, a facility licensed as an inpatient hospital always uses the hospital entity code, regardless of the specific department or service provided. Correctly identifying the entity code before submission minimizes billing errors and supports successful claim submission.

Common Issues and Ensuring Accuracy

Errors related to the entity code on the UB-04 form are common and can impede claim processing. Mistakes include using an outdated code, misidentifying the facility’s type, or data entry errors during form completion. For example, a facility might mistakenly use a code for a rehabilitation center when it is primarily licensed as an acute care hospital. Such discrepancies lead to claim rejections.

When an entity code is incorrect, the claim will be denied or returned to the provider for correction, leading to delays in reimbursement. This can impact a healthcare organization’s cash flow and increase administrative burdens. An incorrect code may also trigger additional scrutiny from payers, potentially leading to audits or further requests for information. Ensuring accuracy requires attention to detail and consistent verification.

To avoid these issues, billing departments should regularly cross-reference their facility’s classification with current official guidelines, such as those published by CMS. Implementing internal verification processes, where multiple individuals review UB-04 forms before submission, can catch errors. Using up-to-date billing software with current code sets also helps maintain accuracy and reduces manual input mistakes.
