New path and lab codes

Hello,

We had recieved a set of CPT® codes used for genetic testing for Fragile x syndrome. We don't bill them but we have to pre-certify the lab testing with the insurance carriers.

83891-83892,83893,83896,83897, 83900 83909 and 83912-have all been deleted for 2013! The replacement codes are all greek to me.

Does anyone have a good resource with a crosswalk from 2012 to 2013 codes for genetic testing?

Thank you
Louise
