Which modifier indicates that an additional service was performed on the same date as a primary service?

The correct answer is that the modifier indicating an additional service performed on the same date as a primary service is actually not A. The appropriate modifier used for this situation is often -25. However, in the context of the options given, option A, -11, does not serve this purpose.

Modifier -25 is specifically used to indicate that a significant, separately identifiable evaluation and management service was performed on the same day as another service. This is crucial for proper billing and ensuring that the services rendered are adequately documented and reimbursed.

Modifier -54 is generally used to indicate a surgical procedure that has been terminated prior to the complete service due to special circumstances.

Modifier -76 indicates a repeat procedure or service by the same physician on the same day.

Modifier -52 is used to indicate that a service or procedure has been partially reduced.

Understanding these modifiers is essential for proper coding and billing practices, ensuring that healthcare providers are accurately compensated for the services they provide.
