How To Use CPT Code 0483T

CPT 0483T describes a transcatheter mitral valve implantation or replacement procedure using a percutaneous approach. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples of CPT code 0483T.

1. What is CPT Code 0483T?

CPT 0483T is a code used to describe a minimally invasive procedure for implanting or replacing a prosthetic mitral valve. The procedure is performed using a catheter that is inserted through a small incision in the skin and threaded through a vessel to the heart. The provider may puncture the wall between the ventricle and atrium to place the valve if necessary. This procedure is typically performed to treat mitral valve prolapse or malfunction.

2. Official Description

The official description of CPT code 0483T is: ‘Transcatheter mitral valve implantation/replacement (TMVI) with prosthetic valve; percutaneous approach, including transseptal puncture, when performed.’

3. Procedure

1. The provider makes a small incision through the skin and dissects down to the selected vessel for access.
2. A catheter with the prosthetic valve compressed within its lumen is inserted through the vessel and threaded to the left ventricle of the heart.
3. If necessary, the provider punctures the septum (wall) between the ventricle and atrium to place the prosthetic valve.
4. The provider may modify the existing valve opening to ensure proper placement of the implant.
5. The artificial valve is implanted between the left ventricle and atrium.
6. The provider ensures a return to normal heart function in the patient.
7. The catheter is withdrawn, and pressure is applied over the artery to control any bleeding.
8. The small incision is closed.

4. Qualifying circumstances

CPT 0483T is performed on patients with mitral valve prolapse or malfunction. The procedure is typically reserved for cases where other treatment options have been exhausted or are not suitable. The provider must use a percutaneous approach, and the procedure may include transseptal puncture if necessary. Vascular access, catheterization, balloon valvuloplasty, deploying the valve, repositioning the valve, temporary pacemaker insertion, and access site closure are included in this code.

5. When to use CPT code 0483T

CPT code 0483T should be used when a provider performs a transcatheter mitral valve implantation or replacement using a percutaneous approach. It is important to note that this code should not be used for transcatheter mitral valve repair or other procedures that have their own specific codes. It is essential to review the documentation and guidelines to ensure accurate coding.

6. Documentation requirements

To support a claim for CPT code 0483T, the provider must document the following information:

• Patient’s diagnosis of mitral valve prolapse or malfunction
• Details of the procedure, including the use of a percutaneous approach and any transseptal puncture
• Date of the procedure
• Specific steps taken during the procedure, such as catheter insertion, valve placement, and any modifications made
• Confirmation of normal heart function after the procedure
• Any additional procedures or interventions performed during the same session
• Signature of the provider

7. Billing guidelines

When billing for CPT code 0483T, it is important to ensure that the procedure meets the specific criteria outlined in the code description. The procedure should be performed using a percutaneous approach, and transseptal puncture should be included if necessary. It is also important to review the documentation to determine if any additional procedures or interventions were performed during the same session. Proper coding and documentation will help ensure accurate billing and reimbursement.

8. Historical information

CPT code 0483T was added to the Current Procedural Terminology system on January 1, 2018. There have been no updates or changes to the code since its addition. It is important to stay updated on any future changes or revisions to ensure accurate coding and billing.

9. Examples

1. A provider performs a transcatheter mitral valve implantation using a percutaneous approach on a patient with mitral valve prolapse.
2. A patient with mitral valve malfunction undergoes a transcatheter mitral valve replacement procedure using a percutaneous approach.
3. A provider performs a transcatheter mitral valve implantation with transseptal puncture on a patient with severe mitral valve regurgitation.
4. A patient with mitral valve prolapse undergoes a transcatheter mitral valve replacement procedure using a percutaneous approach and requires temporary pacemaker insertion.
5. A provider performs a transcatheter mitral valve implantation on a patient with mitral valve stenosis using a percutaneous approach and includes left ventriculography to assess valve positioning.
6. A patient with mitral valve prolapse undergoes a transcatheter mitral valve replacement procedure using a percutaneous approach and requires access site closure.
7. A provider performs a transcatheter mitral valve implantation with transseptal puncture on a patient with mitral valve regurgitation and includes angiography for guidance of the procedure.
8. A patient with mitral valve malfunction undergoes a transcatheter mitral valve replacement procedure using a percutaneous approach and requires repositioning of the valve during the procedure.
9. A provider performs a transcatheter mitral valve implantation on a patient with mitral valve prolapse using a percutaneous approach and includes balloon valvuloplasty to prepare the valve site.
10. A patient with severe mitral valve regurgitation undergoes a transcatheter mitral valve replacement procedure using a percutaneous approach and requires diagnostic coronary angiography during the same session.
