C682 – Extended Special Neurology Consultation
OHIP Surgical Procedures Code — Neurology (18) · Schedule of Benefits
An extended special neurology consultation provided to a non-emergency hospital in-patient. This service is subject to the same conditions as A682. As a 'C' prefix code, this service is for acute care hospital – non-emergency in-patient services as described in the General Preamble (). A consultation is an assessment rendered following a written request from a referring practitioner, requiring the opinion of a specialist due to the complexity, seriousness, or obscurity of the case. The consultant must perform an appropriate assessment and provide a written report to the referring practitioner ().
When to Use
- Use C682 for a complex, in-depth neurological assessment of a hospitalized patient where the complexity of the case requires a formal written request from the attending physician.
- Use C682 when the patient requires a comprehensive review of neurological status that exceeds the scope of a standard subsequent visit (C683) due to diagnostic obscurity or severity.
Common Pitfalls
- Billing C682 without a documented, written referral request from the attending physician or nurse practitioner in the patient's chart, which leads to automatic downgrades to a lower assessment fee during audits.
- Attempting to bill C682 for routine follow-up visits; once the initial consultation is complete, subsequent visits must be billed as C683, not as repeat consultations.
- Failing to provide a formal, written report back to the referring practitioner, which is a mandatory requirement for the 'Consultation' designation under GP16.
Billing Tips
- Ensure the referral request specifically identifies the consultant by name and includes the referring practitioner's billing number to satisfy the strict documentation requirements of GP16.
- If the patient is located in an ICU or CCU, remember to append the C101 premium to the C682 claim to capture the additional institutional setting fee.
