Incident-To Billing With a New Patient
A nurse practitioner sees a new patient at a primary care clinic for a routine physical and a chronic condition follow-up. The supervising physician is on site but does not see the patient. The billing staff submits the claim under the physician's National Provider Identifier using incident-to rules and bills at 100 percent of the physician fee schedule. The payer processes the claim and later requests records as part of a routine review. The clinic's compliance officer notes that the nurse practitioner is credentialed with the payer and that the physician was in the building but in a different suite. The claim amount is $210. The clinic has a policy of billing incident-to whenever a physician is on site.
1. Evaluate whether incident-to billing is appropriate for this encounter.
Read the worked answer
Incident-to billing is not appropriate here for several reasons.
First, incident-to requires that the service be part of the physician's established plan of care for an established patient. This is a new patient, so there is no established plan of care and no established patient relationship with the physician. Incident-to cannot be used for new patients.
Second, incident-to requires direct supervision, meaning the physician must be physically present in the same office suite and immediately available to assist. Being in a different suite does not satisfy direct supervision.
Third, the service included a routine physical and chronic condition follow-up, which is a substantive service rather than an incidental follow-up to the physician's plan.
Because the nurse practitioner is credentialed with the payer, the correct approach is to bill the service under the nurse practitioner's NPI at the nurse practitioner's allowed rate, which is typically 85 percent of the physician fee schedule. The incident-to claim overpaid the practice and creates repayment exposure.
2. Recommend the corrective actions and describe the compliance risk.

The clinic should self-disclose and correct the claim. Because this is a payer review and the error is identifiable, the clinic should submit a corrected claim under the nurse practitioner's NPI and refund the difference between the physician rate and the nurse practitioner rate.
The compliance risk is significant. Billing incident-to without meeting all requirements is a false claim, and a pattern of such claims can trigger overpayment recovery, civil monetary penalties, and exclusion risk. The clinic's blanket policy of billing incident-to whenever a physician is on site is itself a red flag because it ignores the established patient, established plan of care, and direct supervision requirements.
Corrective actions:
- Revise the policy to require a documented established plan of care and same-suite physician presence before incident-to billing.
- Add a hard stop in the billing system so new patients cannot be billed incident-to.
- Audit all incident-to claims from the past 12 months and repay any overpayments.
- Train staff and providers on the distinction between incident-to and direct billing under the nurse practitioner's NPI.
- Document supervision in the record when incident-to is used.
