According to Appendix B (Summary of Additions, Deletions, and Revisions) in CPT 1999, there are only a few changes with regard to E/M (Evaluation and Management) coding. The changes all involve separately coding for Prolonged Physician Service with and without Direct (Face to Face) Patient Contact - Codes 99354 thru 99359. These changes appear to have little relevance to Plastic Surgery.
