National Uniform Billing Committee Official Data Specifications Manual
The Official UB-04 Data Specifications Manual 2019, copyrighted by the American Hospital Association, is the only official source of UB-04 billing information adopted by the National Uniform Billing Committee (NUBC). No other publication—governmental or private/commercial—can be considered authoritative. It contains updated specifications for the data elements and codes included on the UB-04 claim form, and used in the electronic HIPAA Institutional 837 Health Care Claim transaction standard.

NUBC is a voluntary committee chaired by the American Hospital Association (AHA) with representation by national provider and payer organizations.  Approval of the UB-04 form and manual design, and updates are made by the NUBC.  AHA holds the copyright to the Official UB-04 Data Specifications Manual and makes it available through Health Forum, the data and publishing subsidiary of the AHA.

Subscription to the UB-04 Manual is available through single-user and multi-user licenses. Delivered as a PDF e-book, the subscription also provides access to a searchable 19-year archive of the NUBC meeting minutes via the Subscribers Only section of the NUBC website.

Both the single-user and multi-user subscriptions grant licensees use of the UB-04 Manual within their organizations for internal business purposes only. Content cannot be shared, copied, modified or transformed into derivative works. 

To license an electronic version of the UB-04 code set for internal use or integration into products and services, contact the Licensing Department at  

All subscribers are on the same subscription cycle of 7/1 to 6/30; there are no partial or pro-rata subscriptions. The 2019 Manual e-book will be available for your use through June 30, 2019, the end of the licensing period. At that time, the e-book will expire and you will need to purchase a new license for the 2020 Manual.
