How To Use CPT Code 0621T

CPT 0621T describes a procedure called trabeculostomy ab interno by laser, which is a type of microinvasive glaucoma surgery (MIGS). 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 0621T?

CPT 0621T is a code used to describe the trabeculostomy ab interno procedure performed by a healthcare provider using a laser. This procedure is a type of microinvasive glaucoma surgery (MIGS) that involves creating holes in the eye’s trabecular meshwork to improve the drainage of aqueous humor and reduce intraocular pressure in glaucoma patients.

2. Official Description

The official description of CPT code 0621T is: ‘Trabeculostomy ab interno by laser.’

3. Procedure

1. The healthcare provider begins by making a small incision in the cornea, which is the clear outer layer of the eye.
2. They then insert a probe through the incision into the anterior chamber of the eye, which is the space between the cornea and the iris.
3. The probe is used to make direct contact with the trabecular meshwork, which is a translucent tissue that filters aqueous humor.
4. The provider applies laser energy through the probe to create microchannels or tiny holes in the trabecular meshwork.
5. The number of microchannels created may vary, but a typical case may involve around 10 microchannels.
6. After creating the microchannels, the instruments are removed, and the procedure is completed.

4. Qualifying circumstances

CPT 0621T is used for patients with glaucoma who require a trabeculostomy ab interno procedure using a laser. The procedure is performed by a healthcare provider and involves creating microchannels in the trabecular meshwork to improve the drainage of aqueous humor and reduce intraocular pressure.

5. When to use CPT code 0621T

CPT code 0621T should be used when a healthcare provider performs a trabeculostomy ab interno procedure using a laser. It is important to ensure that the procedure meets the specific criteria outlined in the code description.

6. Documentation requirements

To support a claim for CPT 0621T, the healthcare provider must document the following information:

• Patient’s diagnosis of glaucoma and the need for the trabeculostomy ab interno procedure
• Details of the procedure, including the use of a laser and the creation of microchannels in the trabecular meshwork
• Date of the procedure
• Any complications or additional procedures performed
• Signature of the healthcare provider

7. Billing guidelines

When billing for CPT 0621T, ensure that the procedure meets the specific criteria outlined in the code description. It is important to follow the guidelines provided by the payer and accurately report the procedure performed. Additionally, consider any additional codes or modifiers that may be required for proper billing and reimbursement.

8. Historical information

CPT code 0621T was added to the Current Procedural Terminology system on July 1, 2022. There have been no updates to the code since its addition.

9. Examples

1. A healthcare provider performs a trabeculostomy ab interno procedure using a laser to create microchannels in the trabecular meshwork of a glaucoma patient.
2. During a microinvasive glaucoma surgery, a healthcare provider uses a laser to perform a trabeculostomy ab interno procedure, improving the drainage of aqueous humor in a patient with glaucoma.
3. A glaucoma patient undergoes a trabeculostomy ab interno procedure using a laser, which helps reduce intraocular pressure and improve their condition.
