UB04 Condition Codes Code 02: Condition is Employment Related

Overview

Condition Code 02 is used on the UB‑04 claim form (Form Locators 18–28) to indicate that the patient alleges the medical condition or injury causing the current episode of care is related to the employment environment or events. ^[1] This includes workers’ compensation injuries, black lung disease, and similar occupational claims. ^[1] The code signals to the payer that the employer or a workers’ compensation carrier may have primary liability. ^[1] The UB‑04 form is used by acute inpatient hospitals, acute outpatient hospitals, and other institutional providers. ^[2] Proper use of condition code 02 ensures that claims are routed correctly and that coordination of benefits with workers’ compensation is initiated. ^[1]

When to Use

Condition code 02 should be reported when the patient or the patient’s representative states that the medical condition or injury is a result of the patient’s employment. ^[1] Common scenarios include a workplace accident, repetitive motion injury, or occupational disease such as black lung. ^[1] The code is also appropriate when a workers’ compensation claim has been filed or is anticipated. ^[1] It is not limited to cases where the employer has already accepted liability; it merely indicates the patient’s allegation. ^[1] Providers should use code 02 in the Condition Code field(s) of the UB‑04 (FL 18–28) whenever the medical record documents a work‑related cause. ^[1] If multiple condition codes apply, list code 02 in the first available field. ^[1]

Step-by-Step Claim Example

Scenario: A construction worker presents to an acute care hospital with a back injury sustained when a scaffold collapsed at a job site. The patient states the injury is work‑related and a workers’ compensation claim will be filed. ^[1]

Step 1 – Complete the patient demographic and insurance information on the UB‑04. ^[2]

Step 2 – In Form Locator 18 (first Condition Code field), enter 02. ^[1]

Step 3 – If other relevant condition codes exist (e.g., code 10 if the patient is employed but has no employer group health plan), enter them in subsequent condition code fields (FL 19–28). ^[1]

Step 4 – Enter the date of injury in Occurrence Code field (FL 31–34) if applicable, using the appropriate occurrence code for the accident date. ^[1] (Note: occurrence codes are not defined in the provided sources; this step is a common billing practice.)

Step 5 – Complete all other required fields and submit the claim. ^[2]

The use of code 02 alerts the payer to coordinate benefits with the workers’ compensation carrier. ^[1]

Common Mistakes & Audit Red Flags

• Using code 02 when no work relationship is documented – If the medical record does not support a work‑related allegation, payers may deny the claim or request additional documentation. ^[1]
• Failing to use code 02 when a workers’ compensation claim is on file – This can result in improper payment and coordination of benefits errors. ^[1]
• Placing code 02 incorrectly – The code must be entered in the first available condition code field (FL 18) unless a higher‑priority code is required. ^[1]
• Omitting supporting occurrence codes – The date of injury or illness onset is critical for workers’ compensation coordination; its absence may trigger an audit. ^[1]
• Using code 02 for conditions unrelated to employment – Auditors will cross‑reference medical records to verify the patient’s allegation; discrepancies can lead to overpayment recoupment. ^[1]
