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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

How to choose

39501Diaphragm repair
39501 describes repair of a diaphragm laceration. Use 39545 when the operation revises the diaphragm rather than repairing a laceration.
39540Diaphragm hernia repair
39540 is for repair of a chronic traumatic diaphragmatic hernia. Choose 39545 when the documented procedure is revision of the diaphragm.
39560Diaphragm resection
39560 applies when diaphragm tissue is resected and the resulting defect receives a simple repair. 39545 describes revision without specifying resection.
39561Diaphragm resection
39561 applies to diaphragm resection with complex repair. Use 39545 when the operation is a diaphragm revision rather than resection with complex repair.

39545 billing questions

How is diaphragm revision different from repair of a traumatic laceration?

Use 39545 for revision of the diaphragm. Code 39501 describes repair of a diaphragm laceration, rather than revision.

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can modifier 50 be reported for bilateral diaphragm revision?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.

Assistant-at-surgery may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.

How does the multiple-procedure rule affect 39545?

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
