HCPCS Modifier GQ
HCPCS modifier GQ is used to report services delivered via asynchronous telecommunications system.
Guidelines and Instructions
This modifier may be submitted with telehealth services. Generally, interactive audio and video communications must be used to permit real-time communication between the distant site physician/practitioner and the Medicare beneficiary. The patient must be present and participating in the telehealth visit. The only exception to the real-time communication requirement is for federal demonstration projects conducted in Alaska and Hawaii.
- Only in Alaska and Hawaii, asynchronous "store and forward technology," in single or multimedia formats, may be used as a substitute for an interactive telecommunications system
- The originating site and distant site practitioner must be included in the definition of the demonstration program
- "Store and forward" means that asynchronous transmission of medical information to be reviewed at a later time by a physician or practitioner at the distant site
- A patient's medical information may include video clips, still images, X-rays, MRIs, EKGs, EEGs, laboratory results, audio clips and text
- The physician or practitioner at the distant site reviews the case without the patient being present
- "Store and forward" substitutes for an interactive encounter with the patient present; the patient is not present in real-time
- Asynchronous communication does not include telephone calls, images transmitted via fax machines and text messages without visualization of the patient (electronic mail)
- Photographs must be specific to the patient's condition and adequate for rendering or confirming a diagnosis or a treatment plan. Dermatological photographs (e.g., photographs of a skin lesion) may be considered to meet the requirement of a single media format under this instruction.
- A medical professional is not required to present the beneficiary to the practitioner at the distant site unless medically necessary. The decision of medical necessity will be made by the physician or practitioner located at the distant site.
