1What Is the A384 OHIP Code?

The A384 billing code applies to neurologists conducting a comprehensive consultation and management for patients with suspected acute cerebral vascular syndrome (ACVS). Typically, this involves evaluating patients presenting with symptoms of an acute stroke or transient ischemic attack. Physicians will not only assess the patient but will also make critical treatment decisions regarding thrombolysis and oversee post-treatment monitoring, allowing for a more streamlined and integrated approach to care.

This code is often overlooked due to the administrative complexity involved in meeting documentation requirements, such as the precise recording of start and stop times and a detailed consultation request from a referring physician. Missteps in eligibility criteria and the requirement for in-hospital settings with specific imaging facilities might also contribute to missed billing opportunities.

3Eligibility Requirements

To be eligible for billing the A384 code, specific criteria must be met:

  • Timeframe and Conditions: Patients must be seen within the timeframe for eligibility for intravenous thrombolysis therapy as dictated by the Canadian Stroke Best Practices.
  • Facility Requirements: The consultation must occur in a hospital equipped with CT or MRI facilities on-site.
  • Specialist Criteria: Only specialists in Neurology (specialty code 18) are eligible to bill this code.
  • Physician Attendance: The physician must remain in constant attendance with the patient during the service.

Additionally, the service is restricted to one per two consecutive 12-month periods unless certain criteria for a second service are met.

4What Your Clinical Note Must Show

1Consultation Documentation

Accurate and comprehensive documentation is required to bill A384 successfully. Ensure the following:

  • Record the start and stop times of the service.
  • Note the time of onset of symptoms in the patient's permanent medical record.
  • Include a written consultation request from the referring physician, nurse practitioner, or dental surgeon.

5Weak vs. Strong Note Examples

The strong note clearly documents critical times and actions taken, ensuring compliance with billing requirements, whereas the weak note lacks specificity and completeness.

Weak Note

Patient presented with stroke symptoms. Treated accordingly, typical recovery. Consultation lasted about an hour.

Strong Note

Patient presented to ER with acute stroke symptoms witnessed at 14:00. Consultation initiated at 14:15 and concluded at 15:45. Administered intravenous thrombolysis at 14:50, and post-treatment monitoring continued for 30 minutes. CT confirmed thrombolytic candidacy. Constant attendance noted throughout.

  • Documented start: 14:15, end: 15:45.
  • Thrombolysis given at 14:50 post-CT confirmation.

6Common Reasons This Code Is Missed

1
Lack of Detailed Documentation
Failure to record the start and stop times or onset of symptoms can render the service non-billable.
2
Incorrect Facility Type
Billing occurs without the proper hospital facilities available for CT or MRI.
3
Specialist Misclassification
Only Neurologists (specialty code 18) may bill this code; other specialists attempting will face denial.
4
Frequency Limits Exceeded
Overlooking billing limits per the defined periods or misinterpreting patient eligibility can cause claims to be rejected.
