For 27605:
"Because the code definition indicates this is a separate procedure, you should report the service only when not integral to the performance of a larger procedure that takes place at the same time.
These separate procedures by definition are usually a component of a more complex service and are not identified separately. They may be reported when performed alone or with other unrelated procedures or services. If performed alone, list the code; if performed with other unrelated procedures or services, list the code and append modifier 59, Distinct procedural service."
"Separate procedure" doesn't only discuss separate incisions, it also includes related anatomical sites. A procedure on the Achilles tendon and an amputation of the forefoot, although near each other, are not related anatomical sites, so the codes shouldn't bundle. I'd still check for edits though, just in case.
