20 CFR § 725.714 - How do providers enroll with OWCP for authorizations and billing?
(a) All non-pharmacy providers seeking payment from the fund must enroll with OWCP or its designated bill processing agent to have access to the automated authorization system and to submit medical bills to OWCP.
(b) To enroll, the non-pharmacy provider must complete and submit a Form OWCP–1168 to the appropriate location noted on that form. By completing and submitting this form, providers certify that they satisfy all applicable Federal and State licensure and regulatory requirements that apply to their specific provider or supplier type.
(c) The non-pharmacy provider must maintain documentary evidence indicating that it satisfies those requirements.
(d) The non-pharmacy provider must also notify OWCP immediately if any information provided to OWCP in the enrollment process changes.
(e) All pharmacy providers must obtain a National Council for Prescription Drug Programs number. Upon obtaining such number, they are automatically enrolled in OWCP's pharmacy billing system.
(f) After enrollment, a provider must submit all medical bills to OWCP through its bill processing portal or to the OWCP address specified for such purpose and must include the Provider Number/ID obtained through enrollment, or its National Provider Number (NPI) or any other identifying numbers required by OWCP.
