Documentation. Physician documentation must include an attestation that supports the physician encounter (e.g. “Patient seen and examined by me”), the individual with whom the service is shared (e.g. “Agree with note by X”), their portion of the rendered service (e.g. “Pulse oximetry 94% on room air. Audible rhonchi at bilateral lung bases. Start O2 2L nasal cannula. Obtain CXR”), the date, and a legible signature. NPP documentation should include as similar reference to the physician with whom the service is being shared for better charge capture. It alerts coders, auditors, and payor representatives to consider both notes in support of the billed service and ensures that the correct notes are sent to the payor in the event of claim denial and subsequent appeal.
Although the visit level is supported by both provider services, only one claim may be submitted for a shared/split service. The rendering provider listed on the claim can be the physician (reimbursed at 100% of the Medicare allowable physician rate) or the NPP (reimbursed at 85% of the allowable physician rate).
Non-Medicare Claims
Shared/split billing policy only applies to Medicare beneficiaries, while independent billing policy applies to Medicare and Aetna. Excessive costs prevent most other non-Medicare insurers from credentialing and enrollment NPPs. Absence of payor policy does not disqualify reimbursement for shared services, but it does require additional measures to establish recognition of NPP services and a corresponding reimbursement model.
After determining payor mix, develop a reasonable guideline for those payors who do not enroll NPPs. Delineate, in writing, a predetermined time frame for guideline implementation unless the payor can provide an alternate billing option. Some experts suggest physician groups outline the following key issues when structuring a billing option5:
- Type of NPPs involved in patient care;
- Category of services provided;
- Service location(s);
- Physician involvement;
- Mechanism for reporting services; and
- Documentation requirements.
Guidelines can be developed for any of the billing options (independent, “incident-to,” shared/split). Be sure to obtain written payor response before initiating the billing process.

NPP Billing Reminders
Discharge Day Management Services
Discharge day management (99238-99239) often is delegated to qualified NPPs.3 Because this service is time-based, the final code selection is based upon the total time spent with the patient, and on the patient’s unit/floor, coordinating care prior to the patient leaving the hospital on the day of discharge. If this service is solely provided by the NPP, the NPP must report the appropriate code under his/her own name on the claim form (for eligible payors). If this service is shared with the physician, report the code representing the cumulative, documented time in both notes, provided that each note identifies the face-toface service from each provider, and his/her corresponding participation.
Admission Services
Many questions arise about NPPs performing the admission service because NPPs might not be given “admitting” privileges by the facility in which they practice. NPPs may provide and/or participate in services according to their state scope practice and facility-imposed guidelines. Billing policy supports state law and will reimburse any “independent” service permitted by the state. Facilities may limit NPP scope of practice by disallowing independent admission service but permittin a shared service with the physician. If this service is shared with the physician, report the code representing the cumulative, documented encounter, provided that each note identifies the face-to-face service from each provider, and his/her corresponding participation
Consultation Services
Prior to Medicare’s elimination of consultation services (99241-99245, 99251-99255), shared/split billing rules excluded consultations from this claim-reporting model.3 Since the elimination of consults, “consultations” are reported as initial hospital care services (99221-99223).3 Therefore, consultative services can be shared by NPPs and physicians, and reported as a cumulative initial hospital service through the shared/ split billing model. Other payors still accept consultation codes and do not have a specified shared/split model. This allows for the consultative service to be reported as a cumulative NPP/physician effort under the physician name, as long as a written contractual agreement exists allowing this billing option.
