Question: Our physician did a spinal epidural catheter revision. This was a tunneled catheter. The patient was asked to come for a follow- up visit during which the patency and functioning of the catheter was checked in addition to the patient's general examination. How can we report the follow-up examination? West Virginia Subscriber Answer: Depending upon whether or not your physician did a laminectomy during the revision, you should submit code 62350 (Implantation, revision or repositioning of tunneled intrathecal or epidural catheter, for long-term medication administration via an external pump or implantable reservoir/infusion pump; without laminectomy) or 62351 (... with laminectomy) for revision of a tunneled epidural catheter. Follow-up exams are common after such catheter revisions. Code 62350 has a 10-day global period, and 62351 has a 90-day global period. If the patient returns for follow-up during the global period, submit code 99024 (Postoperative follow-up visit, normally included in the surgical package, to indicate that an evaluation and management service was performed during a postoperative period for a reason[s] related to the original procedure). Otherwise, you report the appropriate-level E/M service for an established patient based on the documentation requirements.
