Summary & Overview
CPT 66840: Removal of Residual Lens Material by Continuous Aspiration
CPT code 66840 denotes a surgical procedure to remove floating lens material from the vitreous cavity by continuous aspiration during or following artificial intraocular lens implantation. This is a specialized ophthalmic vitreoretinal intervention that addresses retained lens fragments that can cause inflammation, elevated intraocular pressure, and vision impairment if not removed. Nationally, appropriate coding for this procedure affects surgical quality metrics, reimbursement for ophthalmic practices, and access to timely vitreoretinal care.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for retained lens material management, typical sites of service, and common billing considerations. The publication summarizes benchmarks and coverage patterns where available, highlights relevant coding practice points for CPT code 66840, and outlines policy and documentation areas that influence payment and utilization. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 66840 describes the removal of floating lens material remaining in the vitreous cavity during artificial lens implantation using continuous aspiration. The procedure may be performed in a single stage or in multiple stages as clinically indicated.
-
Service type: Surgical vitreoretinal procedure involving aspiration of residual lens material during or after intraocular lens implantation.
-
Typical site of service: Operating room or ambulatory surgical center for ophthalmic surgery; may be performed in settings equipped for intraocular procedures.
Clinical & Coding Specifications
Clinical Context
A 72-year-old pseudophakic patient presents on postoperative day 1 after cataract extraction with posterior capsule rupture and residual nuclear fragments that have migrated into the vitreous cavity during intraocular lens implantation. The patient reports decreased vision, pain is minimal, and exam shows vitreous opacities with mobile lens material and risk for prolonged intraocular inflammation. After informed consent, the ophthalmic surgeon schedules a pars plana approach under monitored anesthesia care or general anesthesia for removal of the floating lens fragments by continuous aspiration (often combined with vitrectomy). The clinical workflow includes preoperative medical clearance, perioperative antibiotics, anesthesia evaluation, operative vitrectomy with instrumentation to aspirate the lens material (66840 describes continuous aspiration of lens material left in the vitreous during IOL implantation), intraoperative assessment of retinal status, possible placement of an intraocular tamponade if needed, and postoperative follow-up to monitor for elevated intraocular pressure, retinal tears/detachments, or endophthalmitis. Typical site of service is an ambulatory surgery center or hospital operating room. The procedure may be performed in one stage at the time of the original cataract surgery if recognized intraoperatively, or in a staged fashion as a subsequent procedure when fragments are identified postoperatively.
