R700 – Cardiovascular procedures with hypothermia and without bypass
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
A service providing the basic anaesthesia units for cardiovascular procedures performed with hypothermia but without bypass. Per the Schedule, R700 replaces the procedural basic code when hypothermia is used where the basic anaesthesia value is less than 25 units. The anaesthesia fee is calculated using these basic units plus applicable time units.
When to Use
- Use R700 when performing cardiovascular procedures involving active hypothermia without cardiopulmonary bypass where the standard procedural anaesthesia unit value is less than 25.
- Select this code to ensure appropriate unit valuation when the clinical requirement for hypothermia elevates the complexity of the anaesthetic management beyond the standard procedural code.
Common Pitfalls
- Do not bill R700 if the standard procedural anaesthesia code already provides 25 or more units, as R700 is only intended to replace lower-value base units.
- Avoid billing G268 or G269 separately, as the Schedule dictates these are included in the base units for major cardiovascular procedures.
Billing Tips
- Ensure the anaesthesia record clearly documents the use of hypothermia to justify the use of R700 over the standard procedural base code.
- Remember that R700 serves as the base unit value; you must still add the appropriate time units and any eligible modifiers (e.g., ASA status or age-based add-ons) to the claim.
