1What Is the C016 OHIP Code?

The C016 billing code applies to repeat consultations in an anesthesiology context for non-emergency hospital in-patient services in Ontario. It is utilized when an anesthesiologist sees a patient again within the same hospital stay due to a change in the patient's condition, such as a reassessment of a pain management regimen or an airway management assessment in advance of a subsequent procedure. These consultations require a new written referral from a physician, nurse practitioner, or dental surgeon. This can often be overlooked if proper documentation is not maintained, leading to a downgrading of the amount payable.

3Eligibility Requirements

To be eligible for billing under C016, the consultation must be a repeat service for a patient already seen by another physician in the interval since the initial consultation. The following conditions must be met:

  1. A new written consultation request from a referring physician, nurse practitioner, or dental surgeon is required.
  2. The request must be kept in the patient’s medical record unless the service is provided in a setting where common medical records are maintained, such as a hospital.
  3. The service must be conducted for in-patient services, not suitable for emergency settings according to the Anaesthesia listing.
  4. C016 can be billed for virtual services if delivered via video.

4What Your Clinical Note Must Show

1Written Request

A written request for the repeat consultation must be documented.

  • Signed by the referring physician, nurse practitioner, or dental surgeon.
  • Stored in the patient's medical record unless in a common record-keeping setting.
2Consultation Documentation

Detailed record-keeping of the consultation is necessary.

  • Detail the reason for repeat consultation.
  • Notes on the patient's current condition and changes since the last consultation.

5Weak vs. Strong Note Examples

The strong note includes specific referral documentation and comprehensive clinical details, ensuring compliance with billing requirements. The weak note lacks specific information and documentation, risking a downgrade to an assessment fee.

Weak Note

Patient seen for follow-up. No detailed notes recorded. No new referral documented.

Strong Note

Patient presented for repeat consultation due to persistent pain post-surgery.

New referral received from Dr. Smith, indicating reassessment of current pain management regimen.

Thorough evaluation conducted; new analgesia plan documented.

  • Contains new referral documentation.
  • Includes detailed clinical findings and updated treatment plan.

6Common Reasons This Code Is Missed

1
Lack of New Referral
Failing to obtain or document a new written referral before the repeat consultation.
2
Inadequate Documentation
Insufficient detail in the consultation notes to support the repeat service provided.
3
Consultation for a New Problem
Billing a repeat consultation for a new problem rather than the initial one.
4
Inappropriate Setting
Attempting to bill C016 for an emergency setting instead of a non-emergency in-patient service.
5
Virtual Service Billing Error
Billing for a virtual consultation via telephone rather than video, which is not eligible.
