Excision tumor soft tisue

Per cci edit cpt 21930 is bundled with cpt complex repair 13101. However when i look the lay description of cpt 21930, that code excludes complex repair. Can some body help me understandand better this excision from the musculoskeletal section and the complex repair from the integumentary section.
Thank you and i really appreciate it
