Answer: The diagnosis code you are referring to is probably V68.1 (Issue of repeat prescriptions). But if the only reason the patient comes in is to pick up a prescription and the physician does not see her for a documented E/M service, you cannot bill an E/M code.
Insurance carriers consider prescription writing as part of the cost of seeing most patients, much like office supplies. There is no separate CPT code for writing a prescription that carriers will reimburse.
Note: Prescription drug management supports a "moderate" level of risk, according to the table of risk found in CPT's E/M documentation guidelines. Although not a separately billable service, prescription drug management can help to support a higher service level.
You should associate a moderate risk level with a level-four established patient visit (99214) if your physician also documents multiple diagnostic/management options at this visit or orders or reviews a moderate number of tests.
