I've scoured all CPT Assistants and I can't find any clarifications. In CPT assist 8/06 it describes undermining as wide or extensive, nothing more.
I agree 100% with you, Dr needs to document extensive or wide undermining to match CPT verbiage. With that said, closure is an integral part of that procedure and NCCI says "Most HCPCS/CPT code defined procedures include services that are integral to them". Also says "Examples of services integral to a large number of procedures include: Surgical closure and dressings". With all that, you might be fighting a loosing battle anyways.
Good Luck!
