What 96377 covers
This service covers applying an on-body injector, including inserting its cannula, so a prescribed medication can be delivered by timed subcutaneous injection. A common example is applying a pegfilgrastim on-body injector after chemotherapy, with delivery scheduled for later. Office clinical staff typically perform the application and provide instructions about wearing and monitoring the device.
Report the application service, not a separate injection when the device later delivers the dose. Report the medication product separately when applicable. Documentation should identify the medication and dose, the application site, and that the injector was applied and activated. Under the CMS incident-to rule, the service is billed only when performed under physician supervision.
