Who Must Use the UB-04

If you are among the following institutional healthcare providers, you must use the UB-04 form for billing:

• Hospitals: Used for inpatient stays, outpatient services, emergency room visits, facility fees, and when professional components are integral to institutional services. This includes general acute care hospitals, psychiatric hospitals, and rehabilitation hospitals.
• Home Health Services: For billing skilled nursing care, therapy services (physical, occupational, speech), and medical social services provided in a patient’s home.
• Hospice: Utilized for all services related to palliative care for terminally ill patients, including physician services, nursing care, social work, spiritual counseling, and medication management.
• Nursing Facilities: Covers services provided in skilled nursing facilities (SNFs) and intermediate care facilities (ICFs), including long-term care, rehabilitation services, and personal care.
• ICF-MR (Intermediate Care Facilities for Individuals with Intellectual Disabilities): For services provided to individuals with intellectual disabilities or related conditions, focusing on active treatment and personal care.
• Adult Family Care Homes: For services provided in a home-like setting, offering personal care and support for adults who need assistance with daily living activities.
• Assisted Living Services: Used for non-medical care and supportive services provided to individuals who need assistance with daily living, but do not require 24-hour skilled nursing care.
• Private Duty Nursing: For specialized, one-on-one nursing care provided to patients in their homes, beyond typical home health agency services.
• Private Non-Medical Institutions: For facilities that provide care and services to individuals with specific needs, often related to mental health or developmental disabilities, without being primary medical institutions.
• Cost Reimbursed Boarding Homes (Case Mix and Non-Case Mix): For residential facilities that provide lodging and services, with reimbursement based on the level of care required by residents.
• Community Residences for People with Mental Illness: For residential programs offering support, rehabilitation, and supervision for individuals with mental health conditions.
• Residential Child Care Facilities: For institutions providing care, supervision, and therapeutic services for children and adolescents in a residential setting.
• Substance Abuse Treatment Facilities: For billing services related to detoxification, rehabilitation, and counseling for individuals with substance use disorders.
• Flat Rate Boarding Homes: For residential facilities providing lodging and basic care at a fixed daily or monthly rate.
• Psychiatric Facilities: For inpatient and intensive outpatient services focused on mental health diagnosis and treatment.

UB-04 vs. CMS-1500: Which Form to Use?

While both the UB-04 and the CMS-1500 are critical healthcare billing forms, they serve distinct purposes and are used by different types of providers:

• UB-04 (Uniform Bill): This form is specifically designed for institutional providers. It’s used to bill for facility charges, inpatient and outpatient hospital services, skilled nursing facility services, hospice care, and other institutional claims. It focuses on the “facility” component of care.
• CMS-1500: This form is used by non-institutional providers, primarily physicians and other professional suppliers, to bill for professional services. It focuses on the “professional” component of care, such as doctor’s office visits, surgical fees, and diagnostic tests performed in a physician’s office.

The key differentiator is the type of service being billed: institutional (UB-04) vs. professional (CMS-1500). Sometimes, a single patient encounter might require both forms if, for example, a physician provides professional services within a hospital setting, resulting in a UB-04 for the facility and a CMS-1500 for the doctor’s professional fee.

Common UB-04 Billing Errors and Best Practices

Accurate UB-04 submission is paramount for timely reimbursement. Common errors can lead to claim denials and delays. Here are some challenges and tips for accurate submission:

• Incorrect or Missing Revenue Codes: Revenue codes describe the specific department or type of service. Ensure these codes accurately reflect the services provided.
• Mismatched Diagnosis and Procedure Codes: The diagnosis codes (ICD-10) must justify the medical necessity of the procedures (CPT/HCPCS) performed.
• Invalid Patient Information: Errors in patient demographics, insurance ID numbers, or policy details are frequent causes of denials.
• Missing or Incorrect Attending Physician Information: Accurate NPI and other identifying details for the attending physician are crucial.
• Lack of Proper Authorization: Many services require prior authorization from the payer. Ensure all necessary authorizations are obtained and documented.

Tips for Accurate Submission:

• Thorough Training: Ensure billing staff are fully trained on UB-04 requirements and updates.
• Regular Audits: Implement internal auditing processes to catch errors before submission.
• Utilize Scrubber Software: Use billing software with claim scrubbing capabilities to identify potential issues automatically.
• Stay Updated: Regularly consult official CMS guidelines and National Uniform Billing Committee (NUBC) resources for the latest changes.
• Clear Documentation: Maintain comprehensive medical records that support all billed services.

Official Resources and Guidelines

To ensure compliance and accuracy, healthcare providers should always refer to the latest official guidance regarding UB-04 billing. Key resources include:

• The official Centers for Medicare & Medicaid Services (CMS) website for institutional billing information.
• The National Uniform Billing Committee (NUBC), which develops and maintains the UB-04 data set and its specifications.

Staying informed through these authoritative sources is critical for successful institutional claim submission.
