X181 – Non-selective angiogram using film changer, cine or multiformat camera
OHIP Laboratory Code — DIAGNOSTIC RADIOLOGY · Schedule of Benefits
This code represents an unspecified procedure. The fee schedule allows for payment to both a surgical assistant (suffix B) and an anaesthetist (suffix C), indicating it is a service of a nature that may require these additional personnel. Specific details regarding the nature of the procedure are not provided in the available context.
When to Use
- Use X181 when performing a non-selective angiogram where the contrast is injected into the aorta or a major vessel rather than a specific branch vessel.
- Use this code as the primary procedure identifier when the imaging requires a film changer, cine, or multiformat camera setup.
Common Pitfalls
- Applying after-hours premiums like E409 or E410 to X181 is a common error; because the base fee is $0.00, these percentage-based premiums will result in $0.00 payment.
- Billing X181 alongside selective angiography codes (e.g., X182) without clear documentation of separate anatomical sites or distinct procedural intent often leads to claim rejection for unbundling.
Billing Tips
- Ensure the documentation explicitly notes the use of a film changer, cine, or multiformat camera to justify the use of X181 over other diagnostic radiology codes.
- If a surgical assistant or anaesthetist is required, bill their services using the appropriate suffixes (B or C) to ensure they receive their respective units, even though the base X181 fee is $0.00.
