We have had a provider say that code 97039 is not a valid code. What we use this code for is interseg intereseg mobil w/heat & vibrate. We have been using this code until recently with no problems. When I called the payer and asked what code we should use instead, the person I talked to told me to use 97022 which is whirlpool therapy. This is not the code I need. Can someone help me figure out what code to use. The person that held my position before said the bills went fine.
