I found the answer to my own question and wanted to share the info with everyone! at
www.medetrac.com they sell very helpful books and software between $120.00 to $250.00 that will let you check the CPT and ICD-9 codes that you are linking, help with billing problems that will keep you from getting denials and so much more. They even have books for specialty areas.
Hope this helps someone!
