Misdiagnosis happens often in in-person health care, but the risks increase with telehealth. Add to this the fact that there is no clear standard of care established by state legislatures, and quality may be uneven between one provider and the next. Misdiagnosis has the potential to drive up overall costs to the general healthcare system as well because misdiagnoses lead to wrong prescriptions and treatments. According to the CDC, one-third of antibiotics prescriptions are already unnecessary. Additionally, if a telehealth service cannot determine a diagnosis, the patient may be counseled to go to an ER or an urgent care service. If these visits are unnecessary, they may result in a large cost to both the patient and the system as a whole.
