1What Is the A416 OHIP Code?

A repeat consultation, billed under OHIP code A416, is designed for gastroenterologists to reassess a patient for the same issue they've previously consulted on. This occurs when a patient's condition resurfaces after interim treatment by another physician, as in cases of inflammatory bowel disease relapses. Billing for a repeat consultation requires a new written referral from the patient's healthcare provider.

In gastroenterology, repeat consultations serve crucial roles in managing ongoing conditions and ensuring patient well-being through continuity of care. Code A416 allows specialists to reevaluate symptoms that persist or recur, providing deeper insights and updated treatment plans.

Mistakes can happen if administrative and referral requirements are overlooked. The necessity of a fresh referral and documentation can be areas where billing for repeat consultations is often misunderstood or misapplied.

3Eligibility Requirements

To bill OHIP for code A416, specific eligibility criteria must be met:

  • A new written referral must be obtained for each repeat consultation, signed by a referring physician, nurse practitioner, or dental surgeon.
  • A copy of this referral must be retained in the consulting physician's medical records unless the consultation is within an institution with shared medical records.
  • Repeat consultations are excluded from the typical frequency limits, provided all other conditions are met.
  • The service may be conducted virtually but only through video, and it should be billed as A416A.
  • If these requirements are not met, the payable amount may be reduced to a general or specific assessment fee.

4What Your Clinical Note Must Show

1Documentation for Billing A416

Ensure you secure and file necessary documentation for a valid A416 billing.

  • Maintain a written request signed by the referring physician, nurse practitioner or dental surgeon.
  • File the referral within the patient's medical record, except in shared record environments.
  • Confirm the written request aligns with the clinical onset and history.

5Weak vs. Strong Note Examples

The strong note provides a complete clinical picture, updates on symptoms, and explicitly mentions the new referral, ensuring clear documentation supporting the repeat consultation billing.

Weak Note

Patient seen today for management of previously known condition. Follow-up required due to symptom recurrence.

Strong Note

Repeat consultation conducted for relapsed inflammatory bowel symptoms after initial consultation and family physician care. Patient previously treated successfully but presents with increased abdominal pain and altered bowel habits. New referral obtained from primary care provider.

  • Detailed patient history updates
  • Specific mention of symptom changes
  • Reference to new referral and prior care
