C018
C018 – Subsequent visit by consultant anaesthetist (hospital/institution)
OHIP Surgical Procedures Code — CONSULTATIONS AND VISITS · Schedule of Benefits
Concurrent care is any routine assessment rendered in hospital by the consultant following the consultant’s first major assessment of the patient when the family physician remains the most responsible physician but the latter requests continued directive care by the consultant.
When to Use
- Use C018 when providing ongoing anaesthesia-related consultation or management for a patient admitted to hospital under a different MRP, such as managing a complex pain block or post-operative respiratory support.
- Use C018 for routine follow-up assessments after the initial consultation (C010) has been completed and the patient remains under the care of the primary attending physician.
Common Pitfalls
- Billing C018 when you are the MRP; this code is strictly for consultant care and will be rejected if the patient is admitted under your service.
- Exceeding the weekly frequency limits of 4 claims in the first week and 2 claims thereafter, which will trigger automatic rejections or audit flags.
- Attempting to bill E083 or E084 premiums with C018, as these premiums are restricted to the MRP and are incompatible with consultant-level billing.
Billing Tips
- Ensure the medical record clearly reflects the request for continued directive care from the MRP to justify the necessity of the concurrent assessment.
- If the patient develops a new, unrelated acute condition requiring a separate assessment, bill C121 instead of C018 to avoid the concurrent care frequency restrictions.
