1What Is the C210 OHIP Code?

What is the C210 OHIP Billing Code?

The C210 code under Ontario's OHIP billing system is designated for a special anaesthetic consultation, primarily within a hospital in-patient context. This service is typically rendered by an anesthesiology specialist when an in-depth evaluation is required, either preceding complex or urgent surgery or related to a significant anaesthetic issue such as a difficult airway or chronic pain management involving the patient.

An anaesthetic consultation of this nature involves at least 50 minutes of direct contact time with the patient. It is crucial for managing cases that demand a higher level of expertise and attention due to the complexity, seriousness, or urgency involved.

Physicians might miss billing this code due to confusion with standard evaluation codes or forgetting to document the start and stop times, both of which are critical components for accurate billing.

3Eligibility Requirements

Eligibility Requirements for C210

The C210 service can be billed under the following conditions:

  • Direct Patient Contact: At least 50 minutes of direct patient contact must be involved in the consultation, exclusive of any other billable services.
  • Written Request: Must be initiated by a written request from a referring physician, nurse practitioner, or dental surgeon, specifying the necessary services and identifying both the consultant and patient.
  • Recording Requirements: The start and stop time of the service must be recorded in the patient's permanent medical record.
  • Billing Frequency: Generally, one service per two consecutive 12-month periods for the same patient, physician, and diagnosis. Exceptions allow for a second service within the same period for in-patients or those in the Emergency Department, if more than 12 but less than 24 months after the first service.
  • Virtual Care: This code is eligible for virtual delivery via video (C210A), but not by telephone.

4What Your Clinical Note Must Show

1Documentation Requirements

Ensure the following are documented for C210 services:

  • Written consultation request from a referring provider, signed and specifying necessary details such as consultant name, specialty, and patient identification.
  • The start and stop times of the consultation recorded in the patient's medical record.
  • A comprehensive written report provided to the referring provider summarizing findings, opinions, and recommendations.

5Weak vs. Strong Note Examples

The strong note clearly documents the duration, context, and specifics of the consultation, alongside the referral request, whereas the weak note lacks critical details and timing, making it insufficient for C210 billing.

Weak Note

Consultation performed on patient admitted for surgery. Discussed anaesthetic plan.

Strong Note

Performed a special anaesthetic consultation on Patient Doe, as per Dr. Smith's request, due to a complex airway. Consultation started at 09:00 and ended at 09:55. Assessed past medical history, current condition, and recommended a tailored anaesthetic strategy involving XYZ approach. Detailed findings and plan have been documented and shared with Dr. Smith.

  • Specific patient details and context
  • Precise timing of the consultation
  • Clear reference to the consultation request and outcomes

6Common Reasons This Code Is Missed

1
Failure to Document Exact Timing
Not properly recording start and end times can lead to non-payment for the code.
2
Inadequate Time with Patient
Not meeting the required 50 minutes of direct patient contact may cause billing issues.
3
Missing Written Request
Without a penned request from a referring provider, the consultation may be billed at a lesser rate.
