Question:
Can we bill 94664 for patients who are already using devices to administer treatments at home?
Answer:
Code 94664 should not be billed for patients who routinely use the device that is being provided for treatment or if a caregiver is already providing those treatments, because then it is not considered medically necessary. However, if documentation in the medical record supports that the patient has demonstrated poor technique in using the device and requires evaluation, then billing for 94664 would likely be appropriate. Note that this code may be reported one time per date of service even if both the demonstration and evaluation components are provided.
