Ophthalmic surgery
About 66990: Ophthalmic endoscope use during surgery
Reports use of an ophthalmic endoscope as an adjunct to a primary eye procedure, such as when endoscopic visualization or treatment is performed.
This add-on identifies use of an ophthalmic endoscope during another eye operation, such as to visualize or deliver treatment to structures that are difficult to see directly. Ophthalmic surgeons may use it for endoscopic photocoagulation or other endoscope-assisted work during procedures involving the anterior segment or ciliary body. It describes the endoscope use, not the primary operation itself.
Report 66990 only with a qualifying primary procedure; it is not a standalone service. The operative report should identify the primary procedure and explain the endoscope’s use and the tissue or treatment target. CMS treats payment for this add-on as within the primary procedure’s global period. Do not use it to separately represent work already included in the primary procedure’s description.

66990 billing questions
Can 66990 be billed by itself?
No. It is an add-on and must be reported with a primary procedure.
What should the operative note show?
Document the primary operation, that an ophthalmic endoscope was used, and its role in visualization or treatment.
Is 66990 the cataract procedure code?
No. A cataract procedure such as 66984 or 66982 represents the primary surgery; 66990 identifies qualifying endoscope use in addition to that procedure.
How does the global period affect payment?
CMS pays 66990 within the global period of the primary procedure with which it is reported.
Is endoscopic cyclophotocoagulation always reported with 66990?
No. Choose codes based on the actual procedure performed and the applicable code description; document whether endoscope use is separately represented by the primary procedure.
