Have you ever had your angiography claims denied or not result in the reimbursements you expected? CPT code 93454 claims are frequently misunderstood by billers, leading to rejections. This often indicates a failure to follow proper billing guidelines.
That’s why we have created this detailed guide on code 93454. We hope that with the help of this guide, you will be able to file this vital angiography code without mistakes. So, let’s start.
CPT Code 93454 – Description
CPT code 93454 is defined as:
“Catheter placement in coronary artery(s) for coronary angiography, including intraprocedural injection(s) for coronary angiography, imaging supervision, and interpretation.”
The definition is a bit hard to process, so let’s break this down into simple words.
Simply put, code 93454 is used to bill an angiography procedure. During the procedure, the healthcare provider inserts a catheter (thin tube) into the coronary artery/arteries. It also includes the administration of intraprocedural injections (contrast dye) that aid in angiographic imaging. Additionally, CPT code 93454 is comprehensive and includes both the imaging supervision and interpretation of these images by a trained provider.
An important point to note here is that this code is specific to coronary angiography procedures performed without left or right heart catheterization. This means that the catheter is placed only in the arteries and does not penetrate the left or right heart chambers.
Another point worth mentioning is that this code encompasses several components that are bundled. According to the Centers for Medicare and Medicaid Services (CMS) and Society for Cardiovascular Angiography & Interventions (SCAI), the following services should not be billed separately:
- Sedation and local anesthesia
- Administration of medicine during catheterization for treatment purposes
- Introduction, positioning, and repositioning of the catheter
- Recording of intracardiac and/or intravascular pressures
- Roadmapping angiography to guide catheter placement
- Catheter removal and access closure
- Imaging supervision, interpretation, report, and recommendations
The primary goal of this procedure is to identify blockages in the arteries that supply blood to the heart. This aids in diagnosing and treating heart conditions, such as coronary artery disease.
Scenarios Where CPT Code 93454 is Applicable
Still confused about billing 93454? To help clarify the concept, here are a couple of real-world scenarios in which this code is applicable:
Unstable Angina
Suppose a 60-year-old man comes to the emergency room. He complains of severe chest pain to the attending physician. He mentions that the pain started suddenly while he was resting at home watching television. The pain feels like heavy pressure on his chest and radiates to his left arm and jaw. The physician also notices heavy sweating and shortness of breath.
Given the unpredictable nature of his symptoms and the fact that the pain occurs even at rest, the physician suspects unstable angina. To check for blockages in the heart’s blood vessels, a coronary angiography is performed along with other tests. The results reveal significant narrowing in multiple coronary arteries that require immediate intervention. In this case, the angiography can be billed using CPT code 93454.
Myocardial Infarction Type 2
Suppose a 60-year-old patient arrives at the emergency room with chest pain and shortness of breath due to severe anemia. The physician diagnoses a type 2 myocardial infarction caused by reduced oxygen to the heart. A coronary angiography is performed to assess the arteries.
The procedure shows no blockages and confirms the diagnosis by ruling out type 1 myocardial infarction (blocked coronary artery). The medical billing department codes and submits the claim for reimbursement. In this case, CPT code 93454 can be employed to bill the imaging.
Applicable Modifiers for CPT Code 93454
To ensure proper reimbursement, you must append the appropriate modifiers to your claims to explain the circumstances of the procedure. Frequently used modifiers with CPT code 93454 include:
| Modifier | Description | When To Use It |
|---|---|---|
| 26 | Professional Component | Used when billing only for the physician’s interpretation and report of the angiography. |
| 59/ X{EPSU) | Distinct Procedural Service | Indicates that the procedure was distinct or independent from other services performed on the same day. |
| TC | Technical Component | Used when billing only for the technical aspects of the procedure (equipment, technician, supplies). |
Apart from these, CMS encourages healthcare providers to append the specific coronary artery modifiers to cardiac catheterization and coronary angiography procedures. The following table provides a summary of these modifiers:
| Coronary Artery Modifier | Description |
|---|---|
| LC | Left circumflex coronary artery |
| LD | Left anterior descending coronary artery |
| LM | Left main coronary artery |
| RC | Right coronary artery |
| RI | Ramus intermedius |
CPT Code 93454 – Billing & Reimbursement Guidelines
Want to bill CPT code 93454 properly? Follow these simple billing and reimbursement guidelines:
Provide Comprehensive Documentation
According to CMS, the patient’s medical record must contain documentation that fully supports the medical necessity for cardiac catheterization and coronary angiography. Required documentation includes:
- Clinical history and physical examination findings
- Results of non-invasive testing, when applicable
- Specific indications for the procedure
- Detailed procedural report including assessment and interpretation
- Any complications or adverse events
Justify Medical Necessity
Justifying the medical necessity for the performed procedure is the most crucial part of filing claims. The CMS clearly states that any cardiac catheterization/ angiography claim submitted without a valid ICD-10 diagnosis code will be rejected. Therefore, always ensure to append a relevant diagnosis code.
The following are some ICD-10 codes that justify the medical necessity of CPT code 93454:
- I20.0: Unstable angina
- I20.1: Angina pectoris with documented spasm
- I20.81: Angina pectoris with coronary microvascular dysfunction
- I21.4: Non-ST elevation (NSTEMI) myocardial infarction
- I21.9: Acute myocardial infarction, unspecified
- I21.A1: Myocardial infarction type 2
You can check the complete list of valid ICD-10 codes via CMS’s guide on cardiac catheterization and coronary angiography.
Check the Medicare Reimbursement Rate
The national average reimbursement amount for 93454 is $835.83 in non-facility settings. For facility settings, exact price data is not available.
The following is a more detailed breakdown of the cost structure:

Wrapping Up
Let’s wrap up this guide. CPT code 93454 is used to bill catheter placement in the coronary artery(s) for coronary angiography. Many services, such as anesthesia and report creation, are already bundled with this code. Avoid billing them separately. Always provide comprehensive documentation with your claims for proper reimbursement.
