What 66940 covers
An ophthalmologist removes the crystalline lens through an incision while leaving the posterior capsule in place. This manual extracapsular approach is distinct from intracapsular removal and from cataract procedures that include placement of an intraocular lens. It is performed in an operating-room setting, commonly when the surgeon chooses a manual extraction rather than phacoemulsification. The code represents lens removal, not implantation of an IOL during the same procedure.
Select this code when the operative report supports extracapsular removal without concurrent IOL placement; document the extraction technique and lens disposition. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity, and co-surgeon payment requires supporting documentation. Team surgery is not permitted.

66940 billing questions
How is 66940 different from 66984?
66940 reports extracapsular lens removal without concurrent IOL placement. Use the applicable cataract extraction code that includes IOL insertion when a lens implant is placed during the same operation.

Does 66940 include an IOL?
No. It reports lens removal without concurrent IOL implantation. The operative note should establish whether an implant was placed and which procedure was performed.
What documentation supports 66940?
Document the manual extracapsular extraction, the operative approach, and whether an IOL was implanted. The record should support choosing this procedure rather than an intracapsular or extraction-with-IOL code.
