South Dakota's geography spans significantly different environments — the eastern agricultural plains, the Missouri River corridor, the Black Hills, and tribal reservation lands across a large portion of the state. Cellular data coverage is robust in Sioux Falls and Rapid City but can be intermittent or absent in frontier counties and on reservation lands where many home care clients live.
GPS-based mobile EVV relies on cellular data. Where the data signal is weak, check-ins may fail, generating GPS location exceptions in Therap even when the caregiver was at the correct address. Telephony-based EVV — where the caregiver calls from the client's location — creates a verifiable time and location record without GPS dependency. South Dakota's Open model permits telephony as an accepted capture method.
Regardless of capture method, exceptions in Therap must be resolved before billing. CareBravo manages the South Dakota Therap exception queue daily as part of its delivered operations, including connectivity-related exceptions common in rural and reservation service areas.
