That's what I used to do too.. I would charge an extra 1%. I mostly did mental health and pediatrics and the auths were pretty time consuming. The only thing I did not do was the clinical aspect of it of course..the OTR's were the responsibility of the client for subsequent billing, I would get the initial auth, track auth's and give reminder reports on the patients that had to have OTR's submitted for subsequent authorizations. Occasionally the provider would send me the completed OTR to file and track.
