What is CPT Code 78458

CPT code 78458 is used for a diagnostic procedure that involves imaging to assess venous thrombosis, or blood clots, in both legs (bilateral). This code specifically refers to the use of imaging techniques, such as ultrasound or other radiological methods, to visualize and evaluate the presence of thrombosis in the veins of both legs. This procedure is crucial for healthcare providers to diagnose and manage conditions related to blood clots, which can lead to serious complications if not properly treated.

Does CPT 78458 Need a Modifier?

When considering the use of CPT codes 78457 and 78458 for venous thrombosis imaging, it's important to determine if any modifiers are necessary to accurately represent the service provided. Here is a list of potential modifiers that could be applicable:

1. Modifier 26 - Professional Component: This modifier is used when only the professional component of the imaging service is being billed. It indicates that the provider is billing for the interpretation of the imaging study, not the technical component.

2. Modifier TC - Technical Component: This modifier is used when only the technical component of the imaging service is being billed. It indicates that the provider is billing for the equipment, supplies, and technical staff involved in the imaging study.

3. Modifier 50 - Bilateral Procedure: This modifier is used when a procedure is performed on both sides of the body. For CPT code 78458, which specifies bilateral imaging, this modifier may not be necessary unless the payer requires it for billing purposes.

4. 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 may be necessary if multiple imaging studies are performed and need to be billed separately.

5. Modifier 76 - Repeat Procedure by Same Physician: This modifier is used when a procedure is repeated by the same physician. It may be applicable if the imaging study needs to be repeated on the same day due to clinical necessity.

6. Modifier 77 - Repeat Procedure by Another Physician: This modifier is used when a procedure is repeated by a different physician. It may be applicable if the imaging study is repeated on the same day by another provider.

7. Modifier 91 - Repeat Clinical Diagnostic Laboratory Test: Although primarily used for laboratory tests, this modifier can sometimes be applicable if the imaging study is repeated for clinical reasons, separate from the initial test.

8. Modifier LT - Left Side: This modifier is used to specify that the procedure was performed on the left side of the body. It may be necessary if the imaging is unilateral and needs specification.

9. Modifier RT - Right Side: This modifier is used to specify that the procedure was performed on the right side of the body. It may be necessary if the imaging is unilateral and needs specification.

It's important to verify with specific payer guidelines and the clinical scenario to determine the appropriate use of modifiers for these CPT codes.

CPT Code 78458 Medicare Reimbursement

To determine if the CPT code 78458 is reimbursed by Medicare, one must refer to the Medicare Physician Fee Schedule (MPFS) and consult with the relevant Medicare Administrative Contractor (MAC) for the specific jurisdiction.

The MPFS provides a comprehensive list of services and procedures covered by Medicare, along with their respective reimbursement rates. Each MAC is responsible for interpreting national Medicare policies and setting local coverage determinations, which can influence whether a particular CPT code is reimbursed in a specific region.

For CPT code 78458, you would need to verify its inclusion in the MPFS and check with your local MAC to confirm coverage and reimbursement specifics. This ensures that the service aligns with Medicare's guidelines and any regional variations in policy.

It is advisable to regularly review updates from both the MPFS and your MAC, as coverage policies can change over time.
