R775 – Cannulation for infusion chemotherapy - superficial temporal artery
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
This cardiovascular surgical procedure involves the cannulation of the superficial temporal artery, performed for the purpose of infusion chemotherapy. Payment for the surgeon, assistant, and anaesthetist are specified. The fees for the surgical assistant and anaesthesiologist are calculated based on a combination of basic units and time units, as detailed in the General Preamble of the Schedule of Benefits (see - for assistants and - for anaesthesiologists).
When to Use
- Use R775 specifically for the surgical cannulation of the superficial temporal artery to establish access for regional infusion chemotherapy.
- Select this code when the procedure is performed as a distinct surgical intervention for chemotherapy delivery, rather than as part of a larger vascular reconstruction or bypass procedure.
Common Pitfalls
- Billing R775 in conjunction with Z402 is prohibited; ensure the claim does not include both codes as they are mutually exclusive.
- Failure to document the specific intent of the cannulation (chemotherapy infusion) can lead to audit scrutiny, as the code is strictly tied to this therapeutic purpose.
Billing Tips
- Ensure that appropriate age-based premiums are applied if the patient is under 16 years of age, as these are eligible additions to the base fee of $109.10.
