1What Is the C046 OHIP Code?
The C046 billing code is designated for repeat consultations within the field of neurological surgery. It is applied to additional consultations rendered by the same neurosurgeon regarding the same presenting problem. This often occurs when a neurosurgeon reassesses an admitted patient previously consulted, with renewed insights following further examination by other healthcare providers. Common scenarios include the reassessment of a traumatic hemorrhage after updated imaging or revisiting a spinal problem once the condition progresses.
Clinically, the use of C046 is crucial when accurate diagnosis and subsequent patient management depend on a new evaluation following care provided by another physician. Due diligence in documentation, reflecting a new written request from a referring provider, ensures compliance with OHIP's requirements.
Failure to secure the appropriate referral could lead to downgrading of the claim to a lower-paying assessment code. This makes the clear documentation of a new written request essential to justify the repeat consultation billing.

3Eligibility Requirements
To be eligible for billing under the C046 code, several requirements must be met:
- The repeat consultation must take place in a non-emergency hospital in-patient setting.
- A new, valid written request from a referring physician, nurse practitioner, or dental surgeon is mandatory.
- A repeat consultation addresses the same presenting problem initially assessed, following subsequent care by another physician between the initial and repeat consultations.
- If these requirements are unmet, the claim may be adjusted to a general or specific assessment instead of a consultation fee. The written referral should be documented in the consulting neurosurgeon's medical records unless the consultation occurs in a facility with shared medical records.
4What Your Clinical Note Must Show
The consultation must be requested in writing by the referring provider.
- Retain a copy of the written request in your medical records unless shared facility records exist.
Ensure the repeat consultation addresses the same presenting problem.
- Document any further assessments or treatments performed by other physicians in the interim period.
5Weak vs. Strong Note Examples
The strong note succeeds in denoting a valid referral and specifying the presenting problem's continuity, essential for billing C046. The weak note lacks documentation of key referral details.
Patient was seen again. No new referral noted.
Received a referral from Dr. Smith for reassessment of the patient's evolving spinal deficit. Conducted a repeat consultation and updated imaging was reviewed.
- Referral documented in patient's file
- Consultation notes reflect reassessment of presenting issue
