Narrowing of the aortic valve or aortic stenosis blocks the flow of blood in the body, forcing the heart to work harder. Typical symptoms of the conditions include chest pain and shortness of breath. Transcatheter aortic valve replacement, also known as TAVR or transcatheter aortic valve implantation (TAVI), is a procedure that treats aortic stenosis. This minimally invasive procedure improves the blood flow in the heart by replacing a narrowed aortic valve with a prosthetic valve.
As TAVR is a high-cost, high-risk procedure, precise documentation and coding is crucial. However, TAVR procedure coding can be challenging because it involves complex procedures, evolving guidelines, and multiple coding layers that must align precisely with documentation. Errors can lead to denials, delayed reimbursement, or compliance issues. Professional cardiology coding services ensure providers are paid accurately and promptly while maintaining regulatory compliance.

This post discusses what transcatheter implantation of the aortic valve involves and how to code the TAVR procedure. It also highlights how AI-powered medical coding streamlines coding and improves claims submission accuracy and compliance for aortic stenosis treatment.
What is TAVR?
TAVR (Transcatheter Aortic Valve Replacement) or transcatheter aortic valve implantation (TAVI) is defined as a minimally invasive procedure used to replace a narrowed aortic valve in patients with severe aortic stenosis. The prosthetic valve is made of metal and animal tissue. While traditional valve replacement requires open-heart surgery, TAVR is performed through very small incisions that leave the chest bones intact.
There are two main approaches to TAVR.
- The transfemoral approach: This is the most common method, which involves accessing the heart through the femoral artery in the groin and does not require a surgical incision in the chest.
- The transapical approach: This option is a minimally invasive surgical technique in which a small incision is made in the chest, allowing access through the apex (tip) of the left ventricle.
In certain cases, physicians may use other alternative access routes to reach the heart.
Once the surgeon establishes the best and safest way to access the site, a catheter is inserted and guided to the heart using advanced imaging techniques till it reaches the native aortic valve. The prosthetic valve is positioned inside the aortic valve, and depending on the valve system used, it may self-expand or be expanded by balloon inflation to anchor it securely within the native aortic valve. After confirming proper valve placement and function, the catheter is removed, completing the procedure.
Who is a Candidate for TAVR?
Transcatheter Aortic Valve Replacement (TAVR) is generally suitable for individuals who have:
- Severe aortic stenosis
- Symptomatic aortic valve disease
The procedure is highly beneficial for both high-risk and low-risk patients who are not good candidates for open-chest surgery due to age or underlying health conditions (e.g., lung or kidney disease, frailty).
However, not everyone with aortic stenosis is a good candidate for TAVR. Patients will undergo a comprehensive evaluation to determine their specific risk, anatomy, and comorbidities to determine their suitability for this complex procedure and to guide treatment planning.
Advanced imaging studies play a critical role in ensuring the patient is an appropriate candidate and to minimize procedural risks. These include:
- Transthoracic and transesophageal echocardiography
- Computed tomography angiography (CTA)
- Coronary angiography, and
- Electrocardiography, chest radiography, and laboratory tests
A multidisciplinary team of cardiologists and surgeons performs this surgical pre-assessment.
How to Code the TAVR Procedure
Accurate coding of the TAVR procedure requires careful review of the clinical documentation, including the indication for the procedure, the access route used, and any associated services or complications. TAVR coding involves assigning the appropriate ICD-10 diagnosis codes to capture the underlying valve disease and procedure CPT codes to describe the valve replacement technique. Correct code selection is essential for compliant reporting, appropriate reimbursement, and accurate quality and outcomes tracking.
ICD-10 Diagnosis Codes Associated with TAVR
The key ICD-10 codes associated with Transcatheter Aortic Valve Replacement (TAVR) include:
Primary ICD Codes for TAVR
- Z95.2 Presence of prosthetic heart valve – used post-TAVR to indicate the patient has a prosthetic aortic valve in place.
- I35.0 Nonrheumatic aortic (valve) stenosis – common underlying diagnosis leading to TAVR; documented via echocardiogram and symptoms.
- T82.03XA Leakage of heart valve prosthesis, initial encounter – used when complications such as paravalvular leak occur after TAVR.
Other relevant ICD-10 codes
- I35.1 – Nonrheumatic aortic insufficiency (if regurgitation is the indication for TAVR).
- I06.0 – Rheumatic aortic stenosis (if valve disease is rheumatic in origin).
- T82.0–T82.9 – Complications of cardiac and vascular prosthetic devices (infection, thrombosis, mechanical failure).
- Z95.4 – Presence of other heart-valve replacement (if xenogenic or other valve type is used).
ICD-10-PCS codes for TAVR
- 02RF37H Replacement of aortic valve with autologous tissue substitute, transapical, percutaneous approach
- 02RF37Z Replacement of aortic valve with autologous tissue substitute, percutaneous approach
- 02RF38H Replacement of aortic valve with zooplastic tissue, transapical, percutaneous approach
- 02RF38Z Replacement of aortic valve with zooplastic tissue, percutaneous approach
- 02RF3JH Replacement of aortic valve with synthetic substitute, transapical, percutaneous approach
- 02RF3JZ Replacement of aortic valve with synthetic substitute, percutaneous approach
- 02RF3KH Replacement of aortic valve with nonautologous tissue substitute, transapical, percutaneous approach
- 02RF3KZ Replacement of aortic valve with nonautologous tissue substitute, percutaneous approach
CPT Codes for TAVR
The 33361–33369 CPT code set is used for billing physician services for TAVR with prosthetic valve:
- 33361 Percutaneous femoral artery approach
- 33362 Open femoral artery approach
- 33363 Open axillary artery approach
- 33364 Open iliac artery approach
- 33365 Transaortic approach (sternotomy/mediastinotomy)
- 33366 Transapical exposure
- 33367 Cardiopulmonary bypass support, percutaneous cannulation
- 33368 Cardiopulmonary bypass support, open peripheral cannulation
- 33369 Cardiopulmonary bypass support, central cannulation
Clear and detailed documentation is essential for accurate TAVR coding.
Documentation Requirements for TAVR
To ensure accurate cardiac surgery coding for TAVR, the surgical documentation should include the following:
- Severity of aortic stenosis: Documentation should clearly specify the severity and type of aortic valve disease requiring TAVR
- Access route used: The procedural approach, such as transfemoral or transapical access, should be accurately documented.
- Valve type and device: Records should identify the specific prosthetic valve and delivery system used during the procedure
- Imaging guidance: Notes should include imaging modalities used for procedural planning and valve deployment, such as echocardiography or fluoroscopy.
- Associated conditions and complications: Comorbidities, concomitant procedures, and any intraoperative or postoperative complications should be documented to support complete coding and reimbursement.
Why TAVR Billing and Coding Is Complex
TAVR billing and coding can be challenging because of complex procedures, evolving guidelines, and multiple coding layers that must align precisely with documentation. Ancillary services (imaging, anesthesia, cardiac catheterization) may be bundled or separately billable depending on payer rules. Misclassification risks underpayment or compliance issues.
Medicare and private insurers require precise documentation of severe aortic stenosis, surgical risk assessment, and multidisciplinary team involvement. Failure to document these can invalidate claims. Post-procedure complications (paravalvular leak, stroke, vascular injury) must be coded accurately to reflect patient risk and justify extended care. Errors in billing and coding can lead to denials, compliance risks, and lost reimbursement.
TAVR coding guidelines evolve as technology advances. Coders must stay current with annual ICD-10 and CPT updates, as well as payer-specific rules.
CMS is reviewing the National Coverage Determination (NCD) for TAVR to reflect expanding indications and advances in care. As TAVR indications continue to expand, updates to Medicare coverage policies may affect patient eligibility and procedural requirements.
