1. Incident-to services are not applicable in ophthalmology
2. Incident-to billing allows non-physician providers to bill for services under the supervising physician’s NPI, provided certain criteria are met
3. Incident-to services can only be billed for procedures, not for evaluation and management services
4. Non-physician providers cannot bill under any circumstances in a physician’s practice
Answer: B
