Question: Is the site resulting from a kyphoplasty procedure considered a surgical wound when answering M1340?
Answer: A percutaneous kyphoplasty procedure that results in a pinpoint needle puncture site, doesn't qualify as a surgical wound, CMS says in the July 2012 Quarterly OASIS Q&As.
But, if the kyphoplasty procedure involves an open approach, requiring a surgical incision, the resulting wound qualifies as a surgical wound for M1340, CMS says. Answer 1 -- Yes, patient has at least one (observable) surgical wound in this case.
