Understanding medicare billing rules is important for providers who desire to maximize the repayment while staying compliant. One most essential concepts many practices overlook is incident to billing. When utilized perfectly, incidents to billing permits services delivered by non physicians practiotionners (NPPs) to be repaid at 100% of the Medicare Physicians Fee Schedule instead of the usual 85%.
However, strict needs apply. Failing to meet them can result in denials, audits, recoupments, or penalties. That is the reason why many individuals rely on expert medical billing services to confirm compliance and optimize income.
What Is Incident To Billing?
Incident to billing is a Medicare billing provision that permits facilities to be billed for services provided by qualified Non-Physician Practitioners (NPPs) to be billed under a supervising physician’s national provider identifier (NPI).
NPPs include:
- Nurse Practitioners.
- Physician’s Assistant.
- Clinical Nurse Specialists.
- Certified Nurse Midwives.
- Clinical Social Workers.
When billed correctly as incident to, Medicare repays the facilities at 100% of the physician fee schedule rate rather than 85%, which may apply when NPPs bill under their own NPI.
Simple Example of Incident to Billing
A physician estimates a Medicare individual with hypertension and establishes a process plan. During a follow-up visit, the individual notices a Nurse Practitioner who measures blood pressure and adjusts medications according to the established care plan. If all incident to needs are met:
- The NP’s services are billed under the physician’s NPI.
- The practice gets 100% repayment.
If needs are not met:
- The NP must bill under their own NPI.
- The practice receives 85% repayments.
