About 66821: Nd:YAG laser capsulotomy for posterior capsule opacification
Laser opening of an opacified posterior lens capsule or anterior hyaloid membrane after cataract surgery, reported per eye with a 90-day global period.
This procedure treats clouding of the posterior lens capsule behind an intraocular lens after cataract extraction. An ophthalmologist uses a laser, usually an Nd:YAG laser, to create an opening that clears the visual axis. The target may include an opacified anterior hyaloid membrane. Treatment is commonly performed in an ophthalmology office or ambulatory surgery center without a surgical incision.
Select 66821 for laser discission of the secondary membrane, including one or more stages needed to complete the capsulotomy; document the affected eye, examination findings, reason for treatment, and laser procedure. Report unilateral treatment with the appropriate laterality modifier. For treatment of both eyes, Medicare pays bilateral reporting with modifier 50 at 150%. Medicare assigns a 90-day global period that includes the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures at 50%. Assistant-at-surgery payment is statutorily restricted; co-surgeons and team surgery are not permitted.

66821 billing questions
Can additional laser sessions on the same eye be billed while completing the opening?
Do not report each stage needed to complete the same capsulotomy as a separate service. The code encompasses one or more stages.
Is modifier 79 automatic if treatment occurs during the cataract surgery global period?
No. Posterior capsule opacity after cataract extraction is not automatically an unrelated condition. Determine whether a separate procedure is reportable during the original surgeon's global period before selecting a postoperative modifier.
Can an eye examination on the day of laser treatment be billed?
Routine preoperative evaluation is included. A separately documented examination that results in the decision to perform this major procedure may be reported with modifier 57.
How is treatment of both eyes reported?
Use RT or LT for one eye. When both eyes are treated, Medicare's bilateral rule provides for modifier 50 and payment at 150%.
Is a surgical assistant payable for this procedure?
No. Medicare has a statutory restriction on assistant-at-surgery payment for 66821; co-surgeons and team surgery are not permitted.
