C600 – Comprehensive cardiology consultation
OHIP Surgical Procedures Code — CONSULTATIONS AND VISITS · Schedule of Benefits
A comprehensive cardiology consultation for a non-emergency hospital in-patient, subject to the same conditions as A600. As a consultation, this service requires a written request from a referring practitioner for the consultant's opinion on a case that is complex, serious, or obscure. The service includes a full assessment of the patient, a review of all relevant data, and the preparation of a written report to the referring source. This service is intended for non-emergency in-patient scenarios within an acute care hospital.
When to Use
- Use C600 for a formal, requested cardiology consultation for a non-emergency hospital in-patient where a comprehensive assessment and written report are required.
- Choose C600 over A600 when the patient is currently admitted to an acute care hospital, as C600 is specifically designated for in-patient settings.
Common Pitfalls
- Billing C600 without a documented, formal written request from the referring practitioner will result in a downgrade to a lesser assessment fee upon audit.
- Attempting to add special visit premiums (e.g., after-hours) to C600 is prohibited; use the appropriate 'A' prefix code if special visit premiums are required for non-elective care.
- Submitting C600 for a consultation requested by a medical trainee or student will trigger a payment adjustment to a lower assessment fee.
Billing Tips
- Ensure the diagnostic code 428 is included on the claim, as it is specifically required for this code to process correctly.
- If you are seeing the patient in an ICU or CCU, you may add the C101 premium to the C600 claim to capture the additional intensity of the setting.
