Ultrasound Guidance with a Carpal Tunnel Injection

Question:

When performing a carpal tunnel injection (20526) using ultrasound, what do I need to document to support reporting 76942?

Answer:

In order to report ultrasonic guidance using CPT code 76942 a permanent image of the ultrasound must be maintained.  It is recommended that you document the imaging guidance in a separate paragraph in the procedure note. Don’t forget medication (J code) can be reported separately for the injection.
