Ophthalmic surgery
About 66984: Standard extracapsular cataract extraction with IOL
Report 66984 for standard extracapsular cataract removal with intraocular lens implantation when complex techniques, endoscopic cyclophotocoagulation, and qualifying drainage-device insertion are absent.
Ophthalmologists typically perform this operation in ambulatory surgery centers or hospital outpatient departments. The surgeon removes the cloudy lens while retaining the capsule needed to support an intraocular lens, usually using phacoemulsification, and implants the lens in the same session. Capsulorrhexis, irrigation and aspiration, viscoelastic use, and wound construction are part of the operation. The operative report should identify the eye treated, lens implantation, and any devices or techniques used.
Report 66984 when the case does not require the devices or techniques that define complex cataract surgery under 66982. Identify a unilateral eye with RT or LT; use modifier 79 for surgery on the other eye during the first eye’s global period. The 90-day global includes the day-before preoperative visit and related postoperative care. Surgical care and transferred postoperative care can be split with modifiers 54 and 55. Same-session bilateral surgery with modifier 50 is paid at 150%. For other same-session procedures, CMS pays the highest-valued procedure in full and reduces others to 50%. Assistant surgery is statutorily unpaid; co-surgeons and team surgery are not permitted.

66984 billing questions
When should 66982 be reported instead of 66984?
Use 66982 when the operative report documents qualifying complex techniques or devices, such as an iris expansion device, capsular tension ring, sutured IOL support, or primary posterior capsulorrhexis. A dense cataract or small pupil alone does not establish that those techniques were used.
How is the second eye billed when surgery is done a few weeks after the first?
Report the second eye’s surgery with the appropriate eye modifier and modifier 79 because it is unrelated to the first eye’s postoperative care. The second eye has its own global period.
How is postoperative care shared with an optometrist?
The surgeon reports 66984 with modifier 54 for surgical care, and the comanaging optometrist reports 66984 with modifier 55 for transferred postoperative care. Both providers should document the transfer and its effective date.
Can a trabecular bypass device or ECP be billed separately with 66984?
For a qualifying internal-approach aqueous drainage device without an external reservoir, use combined code 66991 instead of adding the device insertion to 66984. For cataract surgery combined with endoscopic cyclophotocoagulation, use 66988 instead of 66984.
Can an assistant surgeon be billed for this case?
CMS does not pay an assistant at surgery for 66984 because of a statutory restriction. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
