It may be determined by a professional provider that it is medically necessary to repeat a procedure or service on an individual. When a procedure or service is repeated within 24 hours of the initial encounter, Modifier 76 is used to report the repeated procedure or service. The circumstances requiring that a procedure or service be repeated can include (but are not limited to); a change in a individual's physical status, services repeated for comparative purposes, follow-up after treatment or intervention, tests repeated at different intervals, etc.
Modifier 76 describes a repeated procedure or service by the same professional provider. The modifier should be utilized by a professional provider to indicate that the claim submitted is not duplicative.
