Modifier 25 with Example

When another minor or major procedure is performed, a Separate identifiable Evaluation and Management service is carried out on the Same Day by the Same Physician or Other Qualified Health Care Professional.

Modifier 24 with Example

The procedure is significant and has 90 days global fee period, so all related postoperative treatment or follow-up is included in the payment for the hernia. But, on March 5, the patient returned to have a breast lump evaluated. In this case, append modifier 24 with 99213 CPT code E&M code if MDM is of low complexity.

Modifier 95 and GT

Both modifiers have almost the exact description and use. These are Synchronous Telemedicine Services provided through a Real-Time Interactive video or audio Telephonic, or telecommunication approach. Only the difference is Modifier 95 is used for Commercial insurance, and GT is used for Medicare.

Telemedicine service is a real-time interaction of a physician with the patient located far away from the physician’s office. Therefore, the information exchanged between the patient and physician or other qualified health care professionals during the telephonic communication service must be sufficient to meet the key components and requirements of the service when provided via direct face-to-face interaction. 

So modifier 95 or GT should be appended to E&M service rendered via a telecommunication system.
