There is no separate CPT code for obtaining a Pap smear specimen. It is considered to be part of another service rendered at the same visit. If the specimen is sent to an outside laboratory, CPT code 99000, "Handling and/or conveyance of specimen for transfer from the physician's office to a laboratory," can be submitted for handling the specimen but should not be used for the collection of the Pap smear. Reimbursement of this code is inconsistent.
If the patient has Medicare, you can submit Q0091, but Medicare doesn't reimburse for the preventative medicine codes.
