How To Use CPT Code 66184

CPT 66184 describes the revision of an aqueous shunt without graft to an extraocular equatorial plate reservoir. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information and billing examples.

1. What is CPT Code 66184?

CPT 66184 can be used to describe the revision of an aqueous shunt without graft to an extraocular equatorial plate reservoir. This code is used when the previously placed aqueous shunt needs to be adjusted or replaced due to the patient’s failure to respond or stop responding to the initial surgery.

2. Official Description

The official description of CPT code 66184 is: ‘Revision of aqueous shunt to extraocular equatorial plate reservoir; without graft.’

3. Procedure

1. The provider prepares the patient and administers anesthesia.
2. An ocular speculum is placed in the affected eye to keep it open.
3. The previous incision in the conjunctiva is opened.
4. The provider replaces or moves the tube or plate reservoir on the eye’s equator, which is the imaginary circle running vertically around the eye.
5. The conjunctiva is expanded over the shunt and then closed.
6. The site is flushed with sterile saline and closed with sutures in layers.

4. Qualifying circumstances

Patients eligible for CPT 66184 are those who have previously undergone an aqueous shunt procedure and require revision due to a lack of response or cessation of response to the initial surgery. The revision involves adjusting or replacing the shunt without the use of a graft. The procedure is performed by a qualified provider.

5. When to use CPT code 66184

CPT code 66184 should be used when a revision of an aqueous shunt without graft to an extraocular equatorial plate reservoir is performed. It is important to note that this code should not be used for shunt placement without revision or for shunt placement with graft.

6. Documentation requirements

To support a claim for CPT 66184, the provider must document the following information:

• Patient’s previous aqueous shunt procedure and the need for revision
• Details of the revision procedure, including the replacement or movement of the tube or plate reservoir
• Date and time of the procedure
• Any complications or additional procedures performed
• Signature of the provider performing the revision

7. Billing guidelines

When billing for CPT 66184, ensure that the procedure involves the revision of an aqueous shunt without graft to an extraocular equatorial plate reservoir. It is important to follow the specific documentation requirements and guidelines for accurate billing. Additionally, be aware of the appropriate use of modifiers and any bundling or unbundling rules that may apply.

8. Historical information

CPT 66184 was added to the Current Procedural Terminology system on January 1, 2015. There have been no updates to the code since its addition.

9. Examples

1. A patient who previously had an aqueous shunt placed undergoes a revision procedure to adjust the shunt without graft.
2. A provider performs a revision of an aqueous shunt without graft for a patient who has stopped responding to the initial surgery.
3. An ocular speculum is placed in the affected eye, and the provider opens the previous incision in the conjunctiva to revise the aqueous shunt without graft.
4. The provider replaces the tube or plate reservoir on the eye’s equator during the revision procedure for an aqueous shunt without graft.
5. After expanding the conjunctiva over the shunt, the provider closes the conjunctiva and flushes the site with sterile saline.
6. The revision procedure for an aqueous shunt without graft is performed by a qualified provider.
7. A patient undergoes a revision of an aqueous shunt without graft to an extraocular equatorial plate reservoir due to a lack of response to the initial surgery.
8. The provider documents the details of the revision procedure, including the replacement or movement of the tube or plate reservoir.
9. The revision procedure for an aqueous shunt without graft to an extraocular equatorial plate reservoir is performed on a specific date and time.
10. The provider’s signature is included in the documentation for the revision of an aqueous shunt without graft.
