What 39499 covers
CPT 39499 represents an unlisted surgical procedure involving the mediastinum, the central compartment of the chest between the lungs. It is selected when no listed CPT code specifically describes the mediastinal service performed. It should not replace a listed code that accurately describes the procedure, such as mediastinoscopy with biopsy or mediastinoscopy with lymph node biopsy. The code identifies an unlisted service rather than a particular named operation.
Medicare assigns status C, or carrier priced: CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The contractor also sets the global period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the other procedures are subject to the standard 50% reduction. Report the code for the unlisted mediastinal procedure performed.

39499 billing questions
When should 39499 be used instead of a listed mediastinal code?
Use it when no specific CPT code describes the mediastinal procedure performed. If a listed code accurately describes the service, report that code instead.
How does 39499 differ from 39401 and 39402?
Those codes describe specific mediastinoscopy procedures with biopsy. Use 39499 only when the procedure performed is not described by a listed code.
What should documentation describe for 39499?
Describe the procedure performed, the mediastinal anatomy involved, the approach, and the work done so the unlisted service is clear.
How does Medicare price 39499?
Medicare assigns status C, so CMS publishes no national payment and the Medicare Administrative Contractor sets payment for each claim.
Who sets the global period for 39499?
The Medicare Administrative Contractor sets the global period.
What happens when 39499 is performed with another procedure in the same session?
The highest-valued procedure is paid in full, and the other procedures are subject to the standard 50% reduction.
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.
