 In a freestanding sleep clinic, Charlotte Ware says, a physician practice should bill for the sleep study using the appropriate CPT code without any modifier. But in a hospital setting, you should bill for sleep studies using  modifier -TC to indicate the technical component and the -26 modifier to indicate the professional component, or the physician interpretation of the study. But many in-hospital sleep clinics are still treated as freestanding, says Michael Frye, a physician with Medical University of South Carolina in Charleston.
