How To Use CPT Code 0671T

CPT 0671T describes the insertion of an anterior segment aqueous drainage device into the trabecular meshwork of the eye, without an external reservoir and without concomitant cataract removal. This article will cover the description, official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples.

1. What is CPT Code 0671T?

CPT 0671T can be used to describe the procedure of inserting an anterior segment aqueous drainage device into the trabecular meshwork of the eye. This code specifically applies to cases where there is no external reservoir and no concomitant cataract removal performed. The purpose of this procedure is to help reduce pressure in the eye, particularly in patients with glaucoma.

2. Official Description

The official description of CPT code 0671T is: ‘Insertion of anterior segment aqueous drainage device into the trabecular meshwork, without external reservoir, and without concomitant cataract removal, one or more.’ It is important to note that this code should not be reported in conjunction with codes 66989 and 66991, which are specific to cataract removal with insertion of an anterior segment aqueous drainage device. Additionally, for complex extracapsular cataract removal with intraocular lens implant without concomitant aqueous drainage device, use code 66982. For extracapsular cataract removal with intraocular lens implant without concomitant aqueous drainage device, use code 66984. If the insertion of the drainage device is into the subconjunctival space, use code 0449T.

3. Procedure

1. When the patient is appropriately prepped and anesthetized, the provider begins the procedure.
2. A small incision is made or the needle of a delivery device is inserted through the cornea, which is the clear covering in the front of the eye.
3. The provider then inserts the small drainage device into the trabecular meshwork, which is the tissue responsible for draining aqueous fluid from the eye.
4. The aqueous fluid flows into Schlemm’s canal, a circular drainage canal in the eye.
5. During the session, the provider may place one or more drainage devices as needed.
6. Once the procedure is complete, the instruments are removed.

4. Qualifying circumstances

CPT 0671T is applicable to patients who require the insertion of an anterior segment aqueous drainage device into the trabecular meshwork of the eye. This procedure is commonly performed in patients with glaucoma or other conditions that result in increased intraocular pressure. It is important to note that this code should not be reported with codes 66989 and 66991, which are specific to cataract removal with insertion of an anterior segment aqueous drainage device.

5. When to use CPT code 0671T

CPT code 0671T should be used when the provider performs the insertion of an anterior segment aqueous drainage device into the trabecular meshwork of the eye, without an external reservoir and without concomitant cataract removal. This code is not appropriate for cases involving cataract removal or when an external reservoir is used. It is important to review the documentation and ensure that the procedure meets the specific criteria outlined in the code description.

6. Documentation requirements

To support a claim for CPT code 0671T, the provider must document the following information:

• Patient’s diagnosis and the need for the insertion of an anterior segment aqueous drainage device
• Details of the procedure, including the specific device used and the number of devices inserted
• Date of the procedure
• Any additional relevant information, such as the patient’s response to the procedure
• Signature of the provider performing the procedure

7. Billing guidelines

When billing for CPT code 0671T, it is important to ensure that the procedure meets the specific criteria outlined in the code description. This code should not be reported with codes 66989 and 66991, which are specific to cataract removal with insertion of an anterior segment aqueous drainage device. Providers should also be aware of any additional guidelines or requirements set forth by the payer. It is recommended to review the payer’s policies and guidelines to ensure accurate and appropriate billing.

8. Historical information

CPT code 0671T was added to the Current Procedural Terminology system on January 1, 2022. As of now, there have been no updates or changes to the code since its addition.

9. Examples

1. A provider inserts an anterior segment aqueous drainage device into the trabecular meshwork of the eye to help reduce pressure in a patient with glaucoma.
2. During the procedure, the provider places multiple drainage devices into the trabecular meshwork of the eye to effectively manage intraocular pressure in a patient with advanced glaucoma.
3. In a patient with a history of elevated intraocular pressure, the provider inserts an anterior segment aqueous drainage device into the trabecular meshwork of the eye to improve drainage and reduce pressure.
4. For a patient with refractory glaucoma, the provider performs the insertion of an anterior segment aqueous drainage device into the trabecular meshwork to alleviate symptoms and manage intraocular pressure.
5. A provider inserts an anterior segment aqueous drainage device into the trabecular meshwork of the eye to help manage intraocular pressure in a patient with secondary glaucoma.
6. In a patient with primary open-angle glaucoma, the provider performs the insertion of an anterior segment aqueous drainage device into the trabecular meshwork to improve drainage and reduce intraocular pressure.
7. To address persistent elevated intraocular pressure, the provider inserts an anterior segment aqueous drainage device into the trabecular meshwork of the eye in a patient with glaucoma.
8. For a patient with angle-closure glaucoma, the provider performs the insertion of an anterior segment aqueous drainage device into the trabecular meshwork to alleviate symptoms and manage intraocular pressure.
9. In a patient with neovascular glaucoma, the provider inserts an anterior segment aqueous drainage device into the trabecular meshwork of the eye to improve drainage and reduce intraocular pressure.
10. A provider performs the insertion of an anterior segment aqueous drainage device into the trabecular meshwork of the eye to manage intraocular pressure in a patient with uveitic glaucoma.
