What 39545 covers
Code 39545 represents an operation to revise the diaphragm itself, rather than an initial repair of an acute tear or a hernia repair. A thoracic or other surgeon may revise previously operated diaphragm tissue to correct its prior reconstruction or anatomy. The service is generally performed in an operating room; the code does not specify a particular access route or material.
Select 39545 when the operative report identifies diaphragm revision as the procedure performed. Document the condition prompting revision and the work done on the diaphragm; use a dedicated repair or resection code when that better describes the operation. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
