Cataract Surgery CPT Codes in 2025: Everything You Need to Know

Introduction

Cataract surgery remains one of the most commonly performed procedures in the United States, with millions of Americans undergoing this vision-restoring operation each year. For healthcare providers and billing professionals, accurate use of CPT (Current Procedural Terminology) codes for cataract surgery is critical to ensure proper reimbursement and compliance with payer policies. As we enter 2025, understanding the commonly used cataract surgery CPT codes, their documentation requirements, and associated billing nuances is more important than ever.

In this guide, we’ll cover the most relevant CPT codes for cataract surgery, including phacoemulsification procedures, complex cases, and services that may be bundled or billed separately. Whether you’re an ophthalmologist, billing specialist, or administrator, this post will help you navigate the billing process more effectively.

What is Cataract Surgery?

Cataracts occur when the lens of the eye becomes cloudy, often due to aging, trauma, or other medical conditions like diabetes. Cataract surgery involves removing the cloudy lens and replacing it with an intraocular lens (IOL), restoring clear vision for the patient.

The most common technique today is phacoemulsification, where ultrasonic energy is used to break up the lens before it is suctioned out. This technique allows for a smaller incision, faster recovery, and fewer complications.

Commonly Used CPT Codes for Cataract Surgery in 2025

Here are the key CPT codes associated with cataract surgery procedures:

1. CPT Code 66984

Description: Extracapsular cataract removal with insertion of intraocular lens, manual or mechanical technique (e.g., irrigation and aspiration or phacoemulsification).
Use Case: This is the most frequently used code for routine cataract surgeries using phacoemulsification with IOL insertion.
Notes: Ensure proper documentation to reflect the routine nature of the surgery.

2. CPT Code 66982

Description: Extracapsular cataract removal with insertion of intraocular lens, complex, requiring devices or techniques not generally used in routine surgery.
Use Case: Use this code for complex cases, such as surgeries involving patients with small pupils, pseudoexfoliation syndrome, or the need for special instruments like iris expansion devices.
Documentation Tip: Must specify the complexity and the necessity for additional techniques or tools.

3. CPT Code 66983

Description: Intracapsular cataract extraction with or without IOL.
Use Case: Rarely used today. Reserved for older techniques where the lens and the capsule are removed entirely.
Relevance: Not commonly billed unless a unique surgical situation arises.

4. CPT Code 66991 (Add-on Code)

Description: Insertion of intraocular lens prosthesis using an intraoperative aberrometer.
Use Case: Add-on code used when intraoperative wavefront aberrometry is utilized for precise lens positioning.
Billing Tip: Must be billed alongside a primary cataract surgery CPT code.

Key Billing Tips for Cataract Surgery in 2025

• Use of Modifiers: Depending on whether the surgery is bilateral, staged, or post-complication, modifiers such as -50, -RT, -LT, -79, or -78 may apply.
• Global Period: Cataract surgeries typically carry a 90-day global period. During this time, postoperative care is bundled with the initial surgery fee.
• Documentation Matters: Complex cases must include detailed operative reports to justify the use of CPT 66982. Failing to do so may result in down-coding or denial.
• Bundled Services: Be cautious about services included in the global package. Routine post-op visits and most follow-ups are not separately billable.

Common Payers’ Considerations

Medicare and most private payers require supporting documentation for higher-level codes. Payers may also have different policies for coverage of premium intraocular lenses or refractive error corrections. Always check payer-specific guidelines and pre-authorization requirements.

Stay Updated with CPT Code Changes

Each year, the AMA may update CPT codes or guidelines. While 2025 has retained most of the core cataract surgery CPT codes, any small updates in billing instructions or modifier usage can impact reimbursement. Staying informed is crucial for maintaining compliance and optimizing revenue.

Final Thoughts

Accurate use of CPT codes for cataract surgery is essential for ensuring timely and full reimbursement. While routine surgeries are relatively straightforward to bill, complex cases require careful attention to documentation, modifier use, and payer rules.

For healthcare providers and billing professionals looking to stay compliant and maximize efficiency, partnering with a trusted medical billing company can make a significant difference.
