Can you put a 26 modifier on an evaluation and management code such as 99213?

Yes, a 26 modifier can be applied to an evaluation and management (E/M) code like 99213 if the service involves a professional component that is billed separately. The 26 modifier indicates that only the professional component of the service is being billed, typically in cases where the provider is interpreting results or providing a consultation rather than performing a complete service. However, it is essential to ensure that the circumstances justify the use of this modifier according to payer guidelines.
