Answer: Try 99001 (handling and/or conveyance of specimen for transfer from the patient in other than a physicians office to a laboratory [distance may be indicated]) with a letter explaining the extraordinary circumstances requiring overnight shipping, although this code is only for collecting the sample outside the office.
