Ophthalmology
About 66991: Cataract extraction with lens implant and ECP
Reports cataract extraction with intraocular lens implantation performed in the same session as endoscopic cyclophotocoagulation for a patient with glaucoma.
An ophthalmologist reports this combined service when removing a cataract, implanting an intraocular lens, and performing endoscopic cyclophotocoagulation (ECP) during the same operative session. ECP uses an endoscope to visualize and treat the ciliary processes; the combined approach is used for patients who have both a visually significant cataract and glaucoma. These procedures are typically performed in an ambulatory surgery center or hospital outpatient operating room.
The record should support the cataract extraction, lens implantation, and ECP, including the clinical indications and operative work performed. Choose this code when the cataract procedure includes ECP; use a cataract code without ECP when that treatment is not performed. CMS assigns 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 others at 50%; bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

66991 billing questions
How does this differ from routine cataract surgery with an intraocular lens?
This code includes ECP performed during the cataract and lens implantation session. A cataract code without ECP is used when ECP is not performed.
Does this code include the ECP treatment?
Yes. The code represents cataract extraction, lens implantation, and ECP performed together; document each part of the operative service.
When should the complex cataract variant be considered?
Use the complex variant when the operative circumstances meet the criteria for complex cataract surgery and ECP is also performed. Do not select it solely because the patient has glaucoma.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral surgery reported under the CMS rules provided?
For bilateral surgery, report modifier 50; CMS pays the bilateral procedure at 150%.
Can an assistant surgeon or co-surgeon be paid?
Assistant-at-surgery payment is restricted for this code. 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.
