1What Is the A210 OHIP Code?

What is A210?

The A210 code is for a Special Anesthetic Consultation provided by an anesthesia specialist. This consultation involves a minimum of 50 minutes of direct patient contact and is used for complex cases that require detailed assessment beyond routine pre-anesthetic evaluations.

Clinicians frequently use this when a patient presents with significant cardiac, respiratory, or airway risks that necessitate detailed pre-surgical planning. It is critical to differentiate this service from the standard pre-anesthetic evaluations, which are included in the anesthetic service itself.

Common reasons this consultation code is missed include incorrect categorization of the consultation as a routine exam or failure to document the necessary elements such as time spent with the patient and focusing on unrelated diagnoses.

4What Your Clinical Note Must Show

1Essential Documentation for A210

Physicians must maintain accurate documentation in the patient's medical records.

  • Written referral request from a physician, nurse practitioner, or dental surgeon.
  • Clearly documented start and stop time of the consultation.
  • Detailed reporting including findings, opinions, and recommendations to the referring party.

5Weak vs. Strong Note Examples

The strong note succeeds because it meets all documentation requirements, including start/stop times and a comprehensive referral request, while the weak note lacks specificity and time documentation.

Weak Note

  • Start time: 10:00AM
  • End time: 10:50AM
  • Diagnosis and management plan documented
