Summary & Overview
CPT 66850: Cataract Extraction with Fragmentation and Aspiration
CPT code 66850 denotes surgical cataract extraction performed by mechanically or ultrasonically fragmenting the lens and aspirating the material. This microsurgical procedure is a common ophthalmic operation addressing vision‑obscuring lens opacities and is central to outpatient eye surgery volumes nationwide. The code is relevant to surgeons, ambulatory surgery centers, hospital outpatient departments, and payer medical policy teams because it captures a routine yet resource‑intensive procedure that affects utilization, device supply, and reimbursement workflows.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical description and typical site‑of‑service context, plus an overview of common modifiers and coding considerations provided in the supporting sections. The publication summarizes national benchmarks and payer coverage patterns where available, clarifies coding intent and relationships to related ophthalmic procedures, and highlights policy updates and documentation elements that commonly affect claim adjudication. The material is written for clinicians, billing specialists, and policy analysts looking for a clear reference on how CPT code 66850 is used and interpreted across settings.

Clinical & Coding Specifications
Clinical Context
A 72-year-old patient presents with progressive, visually significant cataract in the right eye causing glare, decreased visual acuity, and difficulty with daily activities. Preoperative assessment includes history, medication review (anticoagulants), ocular exam with slit lamp and dilated fundus exam, biometry for intraocular lens power, and informed consent. On the day of surgery the patient undergoes topical and intracameral anesthesia or monitored anesthesia care depending on comorbidities. The surgeon performs 66850 (phacoemulsification with aspiration) using mechanical or ultrasonic energy to fragment and aspirate the opacified lens nucleus and cortex; an intraocular lens is implanted in the capsular bag as part of the same operative session. Postoperative workflow includes immediate recovery monitoring, topical antibiotic and steroid drops, and follow-up visits on postoperative day one, week one, and one month to assess visual recovery and detect complications such as infection or posterior capsule opacification.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When billing separately for the professional interpretation portion of a diagnostic test related to the procedure |
50 | Bilateral procedure | When both eyes are operated on during the same operative session and payer allows bilateral reporting for cataract surgery
