20 C.F.R. § 725.715 – How do providers submit medical bills?

(a) A provider must itemize charges on Form OWCP-1500 or CMS-1500 (for professional services, equipment or drugs dispensed in the office), Form OWCP-04 or UB-04 (for hospitals), an electronic or paper-based bill that includes required data elements (for pharmacies) or other form as designated by OWCP, and submit the form promptly to OWCP.
(b) The provider must identify each medical service performed using the Current Procedural Terminology (CPT) code, the Healthcare Common Procedure Coding System (HCPCS) code, the National Drug Code (NDC) number, or the Revenue Center Code (RCC), as appropriate to the type of service. OWCP has discretion to determine which of these codes may be utilized in the billing process. OWCP also has the authority to create and supply codes for specific services or treatments. These OWCP-created codes will be issued to providers by OWCP as appropriate and may only be used as authorized by OWCP. A provider may not use an OWCP-created code for other types of medical examinations, services or treatments.
1. (1) For professional medical services, the provider must list each diagnosed condition in order of priority and furnish the corresponding diagnostic code using the “International Classification of Disease, 10th Edition, Clinical Modification” (ICD-10-CM), or as revised.
2. (2) For prescription drugs or supplies, the provider must include the NDC assigned to the product, and such other information as OWCP may require.
3. (3) For outpatient medical services, the provider must use HCPCS codes and other coding schemes in accordance with the Outpatient Prospective Payment System.
4. (4) For inpatient medical services, the provider must include admission and discharge summaries and an itemized statement of the charges.
(c)
1. (1) By submitting a bill or accepting payment, the provider signifies that the service for which reimbursement is sought was performed as described, necessary, appropriate, and properly billed in accordance with accepted industry standards. For example, accepted industry standards preclude upcoding billed services for extended medical appointments when the miner actually had a brief routine appointment, or charging for the services of a professional when a paraprofessional or aide performed the service; industry standards prohibit unbundling services to charge separately for services that should be billed as a single charge.
2. (2) The provider agrees to comply with all regulations set forth in this subpart concerning the provision of medical services or treatments and/or the process for seeking reimbursement for medical services and treatments, including the limitation imposed on the amount to be paid.
