What 67599 covers

This code identifies a procedure involving the orbit for which no dedicated CPT code describes the service. It is selected based on the procedure performed, rather than simply because care involves the eye socket. Listed orbital procedures include implant insertion, implant revision, and optic nerve decompression; those specific services should be reported with their dedicated codes when they accurately describe the work. This code is for a different orbital procedure that lacks a matching listed code.

For Medicare physician fee schedule purposes, status C means CMS publishes no national payment amount and the Medicare Administrative Contractor sets payment for each claim. The contractor also determines the global period. In a session with multiple procedures, the highest-valued procedure is paid in full and the others at 50%; a bilateral procedure reported with modifier 50 is paid at 150%.

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.

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.
