Question:
Do any specific criteria exist for documentation when it comes to 94644?
Answer:
First, understand that the codes within this range represent hourly charges for the delivery of therapy. The charge for the initial-hour code—94644—will include set-up time, device/supplies and medication. Documentation for billing of 94644 must demonstrate that 60 minutes of therapy time occurred. Each additional full 60 minutes of therapy is represented by CPT code +94645.
