CPT code 93458 is used for a procedure involving imaging of the left heart artery and ventricle to assess blood flow and heart function.
CPT code 93458 is used to describe a medical procedure known as a left heart catheterization with coronary angiography. This procedure involves the insertion of a catheter into the left side of the heart to examine the coronary arteries and the left ventricle. It is typically performed to assess the presence of coronary artery disease, evaluate heart function, and guide treatment decisions. The procedure provides detailed images of the heart's blood vessels and chambers, helping healthcare providers diagnose and manage cardiac conditions effectively.
For CPT code 93458, which involves left heart catheterization with coronary angiography, the following modifiers may be applicable:
1. Modifier 26 - Professional Component: This modifier is used when the physician performs only the professional component of the procedure, such as the interpretation of the angiography, without providing the technical component.
2. Modifier TC - Technical Component: This modifier is applied when only the technical component of the procedure is provided, such as the use of equipment and supplies, without the professional interpretation.
3. Modifier 59 - Distinct Procedural Service: This modifier is used to indicate that a procedure or service was distinct or independent from other services performed on the same day. It is applicable when multiple procedures are performed and need to be reported separately.
4. Modifier 76 - Repeat Procedure by Same Physician: This modifier is used when the same procedure is repeated by the same physician on the same day. It indicates that the repeat procedure was necessary.
5. Modifier 77 - Repeat Procedure by Another Physician: This modifier is used when the same procedure is repeated by a different physician on the same day. It indicates that the repeat procedure was necessary.
6. Modifier 78 - Unplanned Return to the Operating/Procedure Room by the Same Physician Following Initial Procedure for a Related Procedure During the Postoperative Period: This modifier is used when the patient returns to the operating room for a related procedure during the postoperative period.
7. Modifier 79 - Unrelated Procedure or Service by the Same Physician During the Postoperative Period: This modifier is used when a procedure is performed during the postoperative period of another procedure, but it is unrelated to the original procedure.
8. Modifier 91 - Repeat Clinical Diagnostic Laboratory Test: Although not typically used with angiography, this modifier is used when a laboratory test is repeated on the same day to obtain subsequent test results.
These modifiers help clarify the specific circumstances under which the procedure was performed, ensuring accurate billing and reimbursement. It is important to review payer-specific guidelines as they may have additional requirements or restrictions regarding the use of modifiers.
The CPT code 93458 is reimbursed by Medicare, provided that it meets the necessary coverage criteria and is deemed medically necessary. Reimbursement for this code is determined by the Medicare Physician Fee Schedule (MPFS), which outlines the payment rates for services covered under Medicare Part B. The MPFS is updated annually and takes into account various factors, including geographic location and practice expenses.
Additionally, Medicare Administrative Contractors (MACs) play a crucial role in the reimbursement process. MACs are responsible for processing Medicare claims and ensuring that services billed are in compliance with Medicare policies. They may have specific local coverage determinations (LCDs) that further define the conditions under which CPT code 93458 is reimbursable. Therefore, healthcare providers should consult both the MPFS and their respective MAC's guidelines to ensure proper billing and reimbursement for this code.
