Hi...I'm really hoping someone can help me out. I am a Clinical Social Worker providing psychotherapy services to residents of group homes/assisted living facilities, etc. The powers that be decided against hiring a billing company with part B expertise and instead are using the company that bills their part A work. We are having a hard time identifying correct codes. I thought that 90801, 90804, 90806, 90808, etc were the correct codes. Am I wrong? have they changed recently? PLEASE help. Any assistance is appreciated!
